I. Additions to the list of Geodephagous Coleoptera of 
Japan, with synonymic and other remarks. By 


H. W. Bates, F.L.S. 
[Read 5th January, 1876.] 


SINCE the publication of my paper on the Geodephagous 
Coleoptera of Japan, in the Transactions of the Society 
for 1873, Part III., a number of genera and species 
belonging to the group treated of have been added to our 
knowledge of the Fauna. In drawing up a list of these 
I have availed myself of the opportunity of making 
various corrections and synonymical remarks. The ac- 
companying Plate refers to some of the more important 
new species described in the former paper. 


Notiophilus impressifrons (Mor.), Putz. Ann. Soc. Ent. 
Belg. t. xvi. p. 10. 
North of Nipon. The name impressifrons is pre- 
occupied by Chaudoir, 1842. 


Carabus DeHaanii (Chaud.) Thomson, in his Opus- 
cula Entomologica, Fascic. vil. p. 728, describes a C. 
japonicus (Mots.), which appears to be the same as this 
species, judging from the words, “ subceruleus, elytris 
catenis 4; . . . tibiis anticis simplicibus.” But how this 
learned entomologist arrives at the conclusion that his 


TRANS. ENT. SOC. 1876.—PART I. (MAY.) B 


a 
2 Mr. H. W. Bates’ Additions to the 


species is the C. japonicus of Motschulsky he does not 
say. Nothing that Motschulsky says in the two descrip- 
tions he published can be strained to harmonize with 
Thomson’s diagnosis. 


C. maiyasanus (Bates). Thomson has erred, also, in 
his determination of this species. I find it difficult to 
understand how an entomologist, in a group like the 
present, can suppose a description like this—* Supra 
cerulescenti-niger, elytris strius impunctatis” (without 
mention of red tibize)—can apply to a species of which the 
original and only description says, “ zeneo-cupreus, elytris 
conspicue crenato-striatis, tibiis et tarsis piceo-rufis ;” these 
characters being constant in all the numerous examples 
taken. 


Carabus Kempferi, Thomson, |. c. p. 729. 


Thomson’s diagnosis fits very well C. insulicola (Chaud.) 
He has made, besides, an unfortunate choice of a name, 
C. Kempferi being the original, although MS. name of 
C. DeHaanii. 

Among the numerous minor characters discovered by 
Thomson, with his well known originality, in the Carabz 
and allied genera, is the dilatation in many of the Japanese 
species of the inner under-edge of the male fore tibize, about 
the middle. This character exists in different degrees in 
the various species allied to C. DeHaanii. In DeHaanti 
(as in the Chinese C. prodigus, fiduciarius, &c.) the tibize 
aresimple. In C. Albrechtii (and its numerous varieties of 
colour and form) the dilatation is very slight, gradual and 
rounded; in C. jaconinus, C. insulicola and C. maiya- 
sanus it is distinctly angular, but with modifications 
according to the species. 


Carabus Van Volzemi, Putzeys, Ann. Soc. Ent. Belg. 
t. xvii. (1875) p. 2. 


IT am indebted to M. Putzeys for a specimen of this 
species, which is very distinct from all those brought home 


by Mr. Lewis.

I failed to see any difference between the Japanese 
insect and an authentic example of C. lata, but the greater 
experience of M. Putzeys has decided that it is not that 
species. 

Tachycellus falsus. 
Harpalus levicollis, Bates, 1. c. p. 261 (nec Dufts.) 


Harpalo levicolli Dufts. simillima; paulo convexior, 
piceus, antennis totis pedibusque fulvis; capitis foveis 
frontalibus sulciformibus utrinque usque ad oculi mar- 
ginem extensis. 

This species, which Morawitz, apparently, as well as 
myself, mistook, on account of its great similarity, for the 
H. levicollis of Europe, I find on closer examination to 
be quite distinct and not to belong to the genus. It has, 
in fact, the oblique frontal sulci or sharply impressed lines 
of Bradycellus and the allied genera, and agrees in all 
essential points with Tachycellus. The basal ventral 
seoment of the ¢ has not the pubescent fovea of the males 
of Tachycellus, but it has a rudimentary impression in 
the same position. 

I do not adopt the name rugicollis, Motsch., for the 
species, as Von Harold, in his notes on Japanese 
Coleoptera (Abhandl. Nat. Ver. Bremen, iv. 1875, p. 285), 
assures us it belongs to H. japonicus, Moraw. 


Oxycentrus Argutoroides, Harpalus id., Bates, |. c. p. 261. 
(Plate I. fig. 3.) 


This curious species belongs to the genus Oxycentrus, 
Chaud. (Bull. Mose. 1854, ii. p. 345), of which the only 
described species, O. parallelus, from Northern India, is 
very distinct from the Japanese one. I have two others, 
from Rangoon and Borneo ;* the genus, therefore, appears

M. Putzeys, having recently expounded the almost

that the species with a central tooth to the mentum, hitherto 
referred to T'rechichus, are more proptrly Perigone.

color (Sturm). 


Amara chalcites, Zimm. 


Mr. Lewis has lately seen, in the collection of 
M. Putzeys, Japanese specimens of this species, no doubt 
authentically named, which he found at once to be quite 
distinct from the Amara taken by him and recorded in 
my former paper as A. chalcites. All his specimens are 
referable to the following :—

II. On a new and remarkable species of Attacus. 
By W. H. Miskin. 


[Read 5th January, 1876.] 


THE following description of what, I believe, to be a 
unique and extraordinary form of this genus of moths will 
probably be read with interest. 


Attacus Hercules, n. sp. 


Ferruginous. 

Male.— Antenne tawny, nearly a fourth as long again as 
thorax, exceedingly deeply and perfectly bipectinate, the 
branches in pairs of equal length. Thorax and abdomen 
same colour as wings, the latter with white band at base. 

Fore wing.—Costa considerably convex apically, fal- 
cate, nearly square at apical angle ; outer margin concave ; 
posterior angle rounded ; semi-hyaline narrow discal band, 
bordered inwardly with black, nearly straight, but arched 
when touching the costa; vitreous triangular discal spot 
attenuated, base rounded, point not touching the band, 
lined round narrowly with white, and again surrounded by 
a narrow band of black, which, on the side parallel with 
the base, is broad and crescent-shaped; some distance 
beyond this, towards the base of the wing, is a cor- 
responding arch of white; a narrow basal transverse band 
of white runs angularly towards the base from median 
vein to abdominal margin ; a rosy patch in apical angle. 

Hind wing.—Long tail; abdominal margin perfectly 
straight, from a little below extremity of abdomen to about 
three-fourths the length of tail, where it slightly dilates, 
then abruptly diverging at an obtuse angle, until it meets 
extremity of outer margin (which is somewhat curved 
from a little above the elbow), forms a long, acutely- 
pointed angle; main branch of median nervure not con- 
tinued down the tail (as in Tropea), but terminating on 
outer margin a little before the tail; there are consequently 
but three nervures contained therein: the submedian 
reaching a little below the elbow, the second median 
branch only reaching to the extreme point, the third in- 
termediate ; basal part of abdominal margin excavated ; 


TRANS. ENT. SOC. 1876.—PART I. (MAY.) 


al 


8 Mr. W. H. Miskin on a new and 


apical angle not rounded ; discal band as in fore wing, but 
quite straight to within short distance of abdominal 
margin, when it curves and touches the margin a little 
way down the tail; vitreous spot as in fore wing, but 
smaller, less attenuated, and less rounded at base ; short 
white transverse band as in fore wings, about equidistant 
between spot and base of wing. 

Underside much lighter in colour and hoary; all the 
dark markings obsolete or indistinct; a white patch at 
base of hind wings. 

Margins of both wings entire. 

Length of body 1’ 7”; expanse of wings 7’ 4”; length 
of abdominal margin to point of tail 4’ 7”; of tail 2’ 3”; 
breadth of tail 4”. 

Female. — Antenne, arising from strongly-developed 
sockets, lightly bipectinate. Thorax and abdomen same 
colour as wings, broad white band at base of latter, and a 
narrow one near apex of same. 

Fore wing rounded towards apex, outer margin 
slightly concave, posterior angles rounded; markings as 
in ¢, except that the discal band is widely bordered 
outwardly by a band of rosy grey, radiated on its outer 
edge; dark rosy patch at extremity of apical angle, bor- 
dered inwardly with white; a short line of rosy pink near 
patch ; vitreous spot much larger in proportion than in ¢, 
nearly touching discal band ; otherwise same as in ¢. 

Hiind wing with short very broad tail, which is nearly 
square, but rather broader than long; abdominal margin 
nearly straight to inner angle of tail, where it is rounded ; 
outer angle of tail rather acute; from a little above com- 
mencement of tail on outer side is a white submarginal 
line continued along bottom of tail (where it is crenated) 
to the inner angle; rosy-grey discal band, not radiated ; 
base of vitreous spot arched, otherwise same as in 4, as 
also other markings. Discal area of both wings a shade 
darker than other parts. 

Underside pale, the dark markings indistinct; the 
white submarginal line in tail as on upper side. 

Length of body 2’ 1”; expanse of wings 9’; length of 
hind wing to inner angle of tail 3’ 7”; of tail, outer edge, 
10°; breadth of tail 1’. 

Hab.—Cape York, Queensland. 

Both specimens are contained in the Collection of the 
Queensland Museum, and are remarkably fine examples. 
They are, as far as I can learn, the only individuals that 


remarkable species of Attacus. 9 


have ever been collected, and were captured at Cape York 
and presented to the Museum ; the ¢ by the late C. D’Oyley 
Aplin, Esq., and the ¢ by F. Jardine, Esq. 

The novel feature in A. Hercules is, of course, the 
tailed hind wings. In every other respect (including the 
neuration of the wings) it agrees with the characters of 
the genus, as given by Walker in the B. M. Catalogues. 
Whether this peculiarity should be considered of sufficient 
importance to justify the creation of a new genus for this 
moth is doubtful. But for the additions to the wings, our 
insect bears a striking resemblance to A. Atlas.

In general form this species somewhat resembles C. splen- 
didula, but is relatively much broader. The eyes are 
larger, and approach nearer to the neck. The thorax is 
broader, and has the sides in front and the anterior angles 
more rounded; the posterior angles are slightly more 
divergent. The elytra are relatively broader and slightly 
more parallel, and the external angle of the apical trun- 
cature is distinct, almost acute. The depth of the striz 
and the convexity of the interstices are as in C. splen- 
didula. 


Hab.— Borneo, Sarawak. Brit. Mus. 


NECROPHAGA. 
SILPHID&. 


NopyNnvs, gen. nov. 


General form elongate, quadrangular, depressed. Men- 
tum trapezoidal; labial palpi short; maxillary palpi 
well developed, the apical joint a little longer than the 
previous joint, subcylindrical. Antenne 11-jointed and 
formed as in Necrophilus. Thorax ample, slightly nar- 
rowed in front, lateral margins thickened and reflexed. 
Elytra quadrangular, truncate at the apex, leaving the 
two apical segments of the abdomen uncovered. Legs 
rather slender; tarsi rather short, the basal joimt ex- 
tremely short, scarcely visible; 2nd, 3rd and 4th joints 
nearly equal, a little elongate, with strong bristles below, 
claw-jomt a little longer than the previous joints taken 
together. 

I think that there can be no doubt that this genus 
should be placed between Necrophilus and Apatetica ; it 
has the antennz of the former combined with the general 
form of Apatetica. It differs from this last, besides the 
antenne, in having the thorax more ample, the elytra a 
little longer, and the proportions of the tarsal joints are 
different, and the 4th joint is not bilobed.

DIAGRYPNODES, gen. nov. 


Elongate, narrow, flat. Head ovate; mandibles very 
stout, prominent: antenne filiform, reaching to the apex 
of the elytra, the basal joint long, club-shaped, very slender 
at its base; the second joint very small, scarcely longer 
than broad, narrowed at the base; the 3rd the same form, 
but } longer ; the 4th to 10th nearly equal, somewhat 
Slemder- the 11th a little longer than the 10th, very 
slender and fusiform. Eyes very small, not prominent. 
Thorax scarcely as broad as the head and about the same 
length, narrowed somewhat suddenly behind the middle. 
Elytra abbreviated, narrow, about the length of the head 
and thorax together. Abdomen long, flat, with five seg- 
ments visible above, rounded at the apex. Femora stout, 
the basal joint to the four anterior tarsi slightly elongate ; 
the 2nd and 3rd subequal and a little shorter than the Ist ; 
the 4th joint shorter, small; 5th jomt as long as the four 
previous joints taken together ; posterior tarsi with only 
four joints, of which the 1st is somewhat ppngee the 2nd 
rather shorter, the 3rd very short. 

This genus ‘should be placed next to Ino.

Hab. —New Zealand. Brit. Mus. 

A single specimen of this beautiful species was sent by 
Mr. C. M. Wakefield in an interesting series of small 
Coleoptera, among which were many examples of the most 
elegant little Longicorn, Zorion guttigerum, Westw. 
(Zorion Batesi, Sharp, Ent. Mo. Mag. 1875). 


Note.—F rom description, Luryplatus lateralis, Motsch., 
Et. Ent. 1859, is certainly Prognatha decisa of Walker, 
Ann. and Mag. N. H. 1858 ( Staphylinide). Motschulsky 
is perfectly correct in placing the genus in the Cucujide. 
Prognotha tenuis, W kr; G. e; 1859, p- 52), is Isomalus 
indicus, Kz., Wiegm. Arch. 1859. Cucujus incommodus, 
Wkr., belongs either to Psammecus or a closely allied 
genus. 


ByRRHID”, 
Nosodendron testudinum, sp. nov. 


Statura omnino NV. fascicularis, at minor; nigrum, vix

Long. 1} lin.; lat. 1 lin. 


The very fine and close punctuation of the head, thorax 
and elytra is only visible with a very strong magnifying 
power. ‘The striz of the ely tra are slightly zig-zag, and 
the transverse striz of the interstices, occurring at regular 
intervals, divide the surface into squares, or, on account 
of the zig-zag longitudinal striz, into hexagons; each 
square or “hexagon js marked in the middle with a some- 
what strong puncture; all the striz, when examined with 
a microscope, are seen to be composed of minute punc-

tures. The prosternum is elongate, triangular, less narrow 
than in NV. fasciculare. The metasternum is only visibly 
punctured in the middle when examined with a powerful 
magnifier, but the sides are very strongly punctured, as 
are also the legs (especially the femora). The abdomen 
is not visibly punctured. 

The mentum has two longitudinal deep grooves, which 
make it appear divided into three parts; this gives it a 
curious appearance, but I think it is not of generic im- 
portance. 


Hab.—Paraé (H. H. Smith). Brit. Mus. 


BYRRHID& v. CRYPTOCEPHALIDA. 
Inclica solida, Walker. 


The type of this insect has just come under my notice. 
It does not belong to the Byrrhide as placed by Walker, 
but is one of the Cryptocephalide, close to (if not congeneric 
with) Monachus. Motschulsky (Bull. Mosc. 1866, i. p. 
412) describes five species of Monachus from Ceylon; and, 
judging from his descriptions, I think it probable that all 
his so-called species are only colour varieties of one, and 
that Inclica solida, W., is only another variety. 

It may be convenient to retain the name Inclica as 
distinct from the American Monachus, as a close exami- 
nation is very likely to bring to light generic differences 
in insects from opposite quarters of the globe. 

Inclica solida, W., 1859 =? Monachus flaveolus, basa- 
lis, suturalis, nigrolimbatus, and acutangulus, Mots. 1866. 


PSEPHENID. 
Tychepsephus, gen. nov. 


General form that of Psephenus, but convex. Head 
formed nearly as in that genus, but less free, owing to the 
prominent angles of the thorax; the mouth is almost 
entirely hidden by the prosternum being produced ante- 
riorly; clypeus very narrow, and rounded in front. 
Thorax transverse, narrowed in front, front margin 
slightly lobed in the middle, the anterior angles some- 
what prominent, base broadly bisinuate. Scutellum 
cordiform. Elytra ample, a little longer than broad, 
convex, a little broader than the thorax at the base, but 
much wider posteriorly, and then gradually narrowed to 
-the apex. Prosternum very slightly produced posteriorly 


al 


16 Mr. C. O. Waterhouse on various 


over a slight triangular impression in the front of the 
mesosternum. Abdomen composed of five segments, the 
apical one not emarginate, the sutures straight. The legs 
are very slender, the four anterior cox are approximate ; 
the tarsi are very long and slender; the Ist joint is very 
long, the 2nd, 3rd and 4th become shorter, the 4th being 
one-half the length of the 1st; the 5th is scarcely longer 
than the 1st. Body above covered with fine scale-like 
pubescence ; underside clothed with silky pubescence. 
The antenne are unfortunately wanting in the Museum 
specimen, but I am enabled, by the kindness of Mr. Jan- 
son, to give the following from a specimen in his collection. 
Antennz reaching to the back of the thorax; basal joint 
elongate, reaching to the middle of the eye, the 2nd joint 
very short, the 3rd nearly as long as the Ist; the following 
joints scarcely shorter than the 3rd, subequal, nearly 
cylindrical, but a little narrowed at their bases. 


Tychepsephus felix, sp. nov. 

Ovatus, convexus, nitidus, obscure piceus, xnescens, 
subtiliter brevissime griseo-pubescens. Capite flavescens, 
sat lato, inter antennas angustato, oculis prominulis, an- 
tennis basi testaceis. Thorace vix convexiusculo, creber- 
rime subtiliter punctulato, longitudine duplo latiori, antice 
subito angustato ; margine antico medio paulo lobato, 
utrinque sinuato; angulis anticis prominulis acutiusculis ; 
lateribus post medium leviter rotundatis, angulis posticis 
fere rectis; marginibus angustissime flavis. Scutello fla- 
vescenti, apice acuto. LElytris basi thorace paululo lati- 
oribus, postice ampliatis, ad apicem arcuatim angustatis, 
convexis, creberrime subtiliter punctatis; dorso depressius- 
culo; humeris obtusis, cum marginibus angustissime flaves- 
centibus. Corpore subtus dense griseo-pubescenti; pedibus 
piceo-flavis. 

Long. 2? lin.; lat. 2 lin. 

Hab.—Chili. Brit. Mus. 

The thorax is at the base nearly straight next to the 
scutellum, but is broadly sinuate on each side, so that at 
first sight it appears only bisinuate. LEpipleural fold of 
the elytra is broad at the base, gradually narrowing to the 
apex, channelled posteriorly. 


MATZ0PSEPHUS, gen. noy. 


General form that of Psephenus : depressed, short, broad. 
Mouth inferior ; mentum trapeziform, small, narrowed in 


new genera and species of Coleoptera. 17 


front ; maxillary palpi long, the apical joint ovoid; labial 
palpi very small, the apical joint small, subulate. Head 
free, broad; clypeus transverse, horizontal, deflexed and 
transversely channelled in front; eyes prominent; an- 
tenn 11-jointed, the 1st jomt elongate, slightly bent ; 
the 2nd globular; the 3rd longer than broad; the 4th 
to 10th scarcely longer than broad, narrowed at their 
bases. Thorax transverse, narrowed in front, bisinuate 
at the base. Elytra oblong, bluntly rounded at the apex. 
Legs slender, the last joint as long as the four preceding 
taken together. Prosternum truncate in front, slightly 
produced behind, and received into a longitudinal impres- 
sion in the mesosternum. Abdomen composed of six 
segments, of which the 4th is very short, the 5th emargi- 
nate, the 6th very small. 

From this description it will be seen that the present 
_insect_ only differs from Psephenus in the form of the 
_clypeus, which is well developed, distinctly separated from 
_the head. I at first took this part for the labrum, but 

I believe I am correct in calling it the clypeus; the 
labrum is very small and transverse, and is hidden by the 
clypeus. The antennz appear more loose in the joints 
than in Psephenus ; they are not in good condition in the 
specimen described. 

In this, as in Psephenus, there are only five well-deve- 
loped segments to the abdomen; it is possible, however, 
that the abdomen may have seven segments in this genus

This species differs chiefly from Psephenus Lecontet in 
being smaller, relatively shorter, the thorax less narrowed 
in front; the elytra relatively shorter and more rounded 
at the apex, and not pubescent. Head free, rather broad, 
eyes prominent, clypeus pitchy. Thorax nearly twice as 
broad as long, gently convex, velvety, slightly lobed over 
the head, narrowed in front (the sides gently arcuate), 
broadest at the posterior angles, which are blunted; the 
base is broadly bisinuate; towards the front margin there 
are indications of two dull red spots. Scutellum small,

This species is evidently closely allied to P. orientalis, 
Coquerel, but (judging from the figure of the thorax, and 
the description ) it differs in having the sides of the thorax 
much less flexuous, indeed they are nearly straight; the 
posterior angles (which are impressed above) are s sarcely 
acute and the extreme point is blunt, and they are not 
directed backwards. ‘The elytra are scarcely broader than 
the thorax at the base, whereas in P. orientalis they are 
said to be much broader.

joint produced and reflexed anteriorly. Eyes hairy. 
Mesosternum not broad, triangularly notched in front to 
receive the prosternum. 

This genus is established by Erichson for some un-

Long. 23 lin.; lat. 1 lin. 

The general form is that of Parnus prolifericornis, but 
it is much more elongate and narrower, and it is not densely 
clothed with pubescence. The head is a little broader, 
the forehead convex with a shallow impression on the 
vertex; the pubescence on the eyes is longer than in that 
species. The thorax is rather narrower, a little more 
convex, the sides are gently arcuate, the anterior angles 
are acute, the posterior angles acute and very slightly 
divaricate and are impressed above. The striz of the 
elytra are deep and the punctures large; the interstices 
are somewhat narrow and gently convex, with scarcely a 
trace of punctuation. The 2nd joint of the antennz is 
large, produced and recurved anteriorly, Of the branches 
emitted by the 3rd to 10th joints that of the 4th is the 
longest; those of the following joimts gradually become 
shorter, the 11th joint is conical.

This species is extremely close to P. Hardwichi. It 
differs in being rather more elongate, in having the thorax 
slightly narrowed posteriorly, so that the greatest breadth 
is just before the angles, whereas in P. Hardwichi the 
thorax gradually becomes broader to the posterior angles. 
The elytra are relatively longer, and the striz are very 
obsolete ; in P. Hardwichi the strix are quite distinct.

large, not very close together, not so close as in S. West- 
woodtt (which the species most nearly resembles), but 
more impressed. ‘The elytra are broader than in S, West- 
wooditi, and less attenuated posteriorly, very convex; the 
punctures forming the striz are not large, and are only 
lightly impressed near the suture; they become larger

The punctures on the thorax are distinct but not very 
strong nor close together, except near the sides; there is 
a very shallow impression near each posterior angle. The 
elytra are very nearly three times as long as the thorax, 
parallel for two-thirds their length and then gradually 
attenuated to the apex; the punctures forming the rows 
are somewhat delicate next the suture; they become deep

a distinct longitudinal impression on the anterior part of 
the disk, and on each side an impression extending from 
the dorsal impression to each posterior angle. The sides 
are very slightly rounded; the anterior angles are acute 
and very porrect. The ely tra are very slightly narrowed 
below the shoulders and then again become more ample, 
not much attenuated towards the apex; the punctures of 
the striz are deep and large and close together ; hence it 
happens that the interstices are very narrow and somewhat

IV. Contributions to an Insect Fauna of the Amazon 
Valiey. Coleoptera—Staphylinide, By D. Sarr, 
M.B. 

[Read 2nd February, 1876. ] 


THERE is probably no part of the world outside of the 
temperate zones of whose insect fauna we know so much 
as we do of that of the valley of the Amazon. During a 
long residence in this interesting region Mr. Bates formed 
rich collections of its Jnsecta, and since his return to 
Kurope has published numerous important memoirs de- 
scriptive of these stores. 

Mr. Bates naturally selected for study those groups 
which are best known, and about which therefore most 
interest is felt by entomologists ; and some few years ago 
he made over to me the whole of the specimens in his 
possession of Amazonian Staphylinide, with the hope 
that I should be able to examine and describe them. 
While I was engaged in this task, Dr. J. W. H. Trail, of 
Aberdeen, made a journey to the Amazon valley in the 
interests of natural history, and on his return handed 
over to me, in the most disinterested manner, the Staphy- 
linide (and some other Coleoptera) collected by him, and, 
as the result, I found myself in possession of an important 
supplement to Mr. Bates’ collection. I have also received 
through Mr. Janson a few species of the family collected 
at Para by Mr. H. H. Smith three or four years ago, and 
one or two interesting species from the upper portion of 
the valley, collected by Mr. Hauxwell, have reached me. 

I am thus enabled to enumerate a considerable number 
of species of the family as inhabiting the valley of the 
Amazon; a large proportion of these species are small, 
obscure and unattractive to the general collector, but 
perhaps on this account their importance just now to the 
genuine student of nature is all the greater; for there 
is prevalent a generally entertained, but I believe quite 
erroneous, opinion as to the existence of minute and 
obscure species of insects in the tropics. It appears to be 
generally supposed that small and unattractive species of 
insects which we all know to be so numerous in temperate 


TRANS. ENT. SOC. 1876.—PART I. (MAY.) 


28 Mr. D. Sharp’s Contributions to the 


regions, are comparatively less frequent in the tropics and 
are there replaced by the brilliant and magnificent forms 
which at present represent the insects of the tropics in 
our collections. I am myself, however, of opinion that 
obscure and minute species of insects are quite as abun- 
dant in the tropics as they are in temperate regions, and 
that the real difference that exists between the tropical 
and cooler regions of the world in this respect is, that in 
the tropics these minute insects are accompanied by a 
large number of brilliant and massive forms, which dis- 
appear gradually as the cold regions are approached. The 
following quotation will show that the removal of such 
misconceptions is of importance. In Lyell’s ‘‘ Students’ 
Elements of Geology,” that very careful author, in alluding 
to the remains of numerous species of insects found in the 
limestone of the Lias, in Gloucestershire, says (p. 342):— 
“The size of the species is usually small, and such as 
taken alone would imply a temperate climate, but many 
of the associated organic remains of other classes must 
lead to a different conclusion.” 

If my estimate of the abundance of obscure forms in 
the tropics be correct, the discrepancy alluded to by Sir 
Charles Lyell, in the passage just quoted, between the 
evidence from insect and that from other classes, would 
be considerably reduced, if not entirely removed. I need 
not, however, insist on this point, for now that we have 
obtained a considerable knowledge of the more striking 
insect forms of the tropics, we are constantly having 
revealed to us glimpses of the enormous number of minute 
species which probably exist there; I may, however, indi- 
cate Mr. Wollaston’s important work on the Cossonide 
recently published by the Society, as illustrative of the 
correctness of my estimate. 

Turning now to the number of species from the 
Amazons, it will be seen that the number here enumerated 
is 487, of which 463 are described as new. The propor- 
tion of new species to those previously described is there- 
fore about as 19:1. This very large proportion of new 
species suggests forcibly how nearly complete is our want 
of knowledge of the Staphylinide of tropical America ; 
nevertheless a good number of Mexican species have been 
described by Fauvel and Solsky, and latterly several 
species from Peru have been made known by the latter of 
these savants; the most important contribution to a know- 


Staphylinide of the Amazon Valley. 29 


ledge of the South American Staphylinide hitherto ob- 
tained, however, is the descriptions contained in Erichson’s 
** Genera et Species Staphylinorum,” of species collected 
by Moritz in Columbia, and by Beske and others in Brazil. 
From these and from some other sources, we have had 
altogether just about 600 species of South American 
Staphylinide previously described, and, as will be seen 
from this paper, I have been able to identify very few 
of these described species with my Amazonian material. 
There is from this fact reason to suppose that, as a rule, 
the individual species of Staphylinide have not a wide 
range in South America, and this opinion is confirmed by 
all the other facts I am acquainted with. It is an inte- 
resting point, however, that the group Piestini seems to 
contain a much larger proportion of widely-distributed 
species than does any other group of the family, the pro- 
portion of new to previously-described species being in it 
only as 34:1. 

This number of 487 species of Staphylinide inhabiting 
the Amazon valley, though it may at first appear by no 
means inconsiderable, is yet, I feel convinced, only a small 
fraction of the species of the group to be found in this 
prolific region. Mr. Bates informs me he only collected 
the species of this family when more important and 
valuable insects of other families were not to be met with; 
while out of the seventy-seven species of Staphylinide 
brought back by Dr. Trail, no less than fifty-five proved 
to be new, and not previously found by Mr. Bates. 
Taking all I know about these insects into consideration, 
I am unable to estimate the number of species of Staphy- 
linide at present existing in Amazonia at less than four 
or five thousand species. 

This paper, therefore, lengthy as it is, is but a preli- 
minary contribution to a knowledge of the Amazonian 
Staphylinide, and in executing my task I have had con- 
stantly to bear in mind that I am only accomplishing a 
very imperfect work. This has been a great discourage- 
ment to me, for recognizing, as I do most thoroughly, 
how difficult is the task of determining obscure and small 
species by means of descriptions, however well drawn up, 
I have been often in doubt as to whether my labour would 
not be wasted, or, at any rate, rewarded only by very 
inadequate benefits to the cause of science. The certain 
discrimination of species by means of descriptions has 


- 


50 Mr. D. Sharp’s Contributions to the 


proved as yet unattainable, and this must, in my opinion, 
continue to be the case until all or ne arly all the actually 
existing species are known to us, and until descriptive 
terms are used with much more precision and definition 
than is at present the case. Hence it happens that a large 
part of the time of those occupied with descriptive ento- 
mology is spent in trying to ascertain the value of the 
names used by their predecessors; and it by no means un- 
frequently happens that the efforts of those predecessors 
have considerably increased instead of diminishing the 
work to be accomplished by their successors. The } prac- 
tical result of these difficulties is, that an increasing im- 
portance is attached to type specimens. This, in my 
opinion, is a perfectly natural and satisfactory result. 
Science teaches us to deal with facts as directly as 
possible, and the actual specimens described by an author 
afford a certainty as to the species he intended which can 
be attainable by no other method. 

The permanent preservation of valuable and fragile 
specimens and the associating of them in an inalienable 
manner with the name given to them, is, however, no easy 
task. But, in order to accomplish it in the case of the 
fragile insects here described, I have devised a method 
of covering and hermetically sealing the type specimens, 
which will, I believe, accomplish their complete protection 
from all destroy: ing agencies except fire and rude physical 
catastrophes. Nearly all the smaller species here de- 
scribed, as well as a considerable proportion of the larger 
species, I have preserved by this method ; and, rendered 
bold by the valuable results it promises, I have ventured 
to describe even minute species where I had but a single 
example of it from which to draw up my description. I 
have taken some steps to test the efficacy of this mode 
of preservation, and hope soon to be able to publish a 
description of the method. 

As regards the terms * South America ” and “ tropical 
America,” constantly used in this paper, I should explain 
that I mean all the parts of the New World south of the 
United States of North America, including the West 
India Islands, but excluding Chili and Patagonia. The 
fauna of Chili is known to he very different from that of 
the countries on the eastern side of the Andes, and of the 
Staphylinide of Patagonia I know absolutely nothing. 

The 487 species here enumerated are divided among

It would be premature for me to attempt to draw any 
important generalizations as to the geographical distribu- 
tion of the different groups, for our knowledge of tropical 
Staphylinide is yet far too meagre to justify this ; but on 
comparing the number of species contained in each sub- 
family with the number of species representing the same 
sub-family in the European fauna, one or two contrasts 
are so striking that they may be mentioned; they are 
the great comparative predominance of 2 inophilint and 
Piestint in the Amazons, and, on the other hand, the 
diminished number of species of Aleocharint and Omalini. 
This latter fact cannot, however, be accepted as more than 
a negative temporary conclusion; and all I think we can 
at present say as the result of a comparison of this sort is 
that the groups Piestiné and Pinophilin?, which are barely 
oe by two or three species in Europe, are richly 

represented in the Amazons. In this respect the fauna 
of the Amazons will, I believe, be found to be similar to 
that of the other warmer parts of the world. 

As regards genera, I have referred the Amazonian 
insects here dealt with to eighty different genera, of which 
I have established twelve as new, but of this part of my 
work I am unable to speak with any feeling of satisfaction. 
My main object in commencing this work was to describe 
the species of Amazonian Staphylinide, and I have only 
concerned myself with genera, because questions of 
nomenclature compelled me so to do. When a man 
describes a new species, the best thing he can do for the 
assistance of others is to mention what ‘previously described 
species it is most nearly allied to. The system at present 
in vogue permits him, however, to avoid doing this by 


all

mentioning a genus to which he supposes it to belong ; and 
thus it happens that when dealing with such an enormous 
mass of species as exist in the Insecta, the very greatest 
confusion arises. We are not only practically at extreme 
variance with our predecessors as to what constitutes a 
genus, but the very greatest discrepancies of opinion 
prevail among presently a active students on this point. 
I should therefore have preferred in this paper never to 
have used the word genus at all, and not to have con- 
cerned myself with the question of genera, for I am quite 
convinced that when dealing with a limited geographical 
fauna the student is not in a position to decide as to 
questions of genera; and this, I hold, would still be the 
case, even if an agreement as to what constitutes a genus 
prevailed among naturalists. The system at present in 
vogue, however, has not allowed me to do this; and in 
accordance with the usual custom of naturalists I have 
had to constantly use the word genus, and to make use of 
the generic system as the basis of my dealing with species. 
I have therefore adopted the plan of making as few new 
generic names as possible. Some farther observations on 
this point will be found among the remarks prefixed to 
the descriptions of the species of Sunius in this paper. 

In examining these insects for description I have paid 
a good deal of attention to the sexual characters, and have 
ascertained in a great number of species not only what are 
the secondary sexual characters of the males, but also 
what is the actual structure of the edeagus. It has long 
been known that the secondary male characters afford 
a most valuable aid to the distinction of the species of 
insects of various orders, and it has also been ascertained 
in several groups of Coleoptera that the edeagus itself 
exhibits very remarkable differences of structure even 
in the case of closely allied species. After making an 
examination of the aedeagus in a large number of the 
species here described, I am led to think that the in- 
vestigation of the structure and variations of this organ 
in the Coleoptera (and no doubt in other insects), would 
lead to highly important biological conclusions. I am 
able to state that in one group of the Staphylinide, viz., 
the Piestini, the edeagus is excessively small, and varies 
but little from species to: species; while in other groups it 
becomes a large complex structure, varying greatly from 
species to species. ‘This is the case in many Pederini, 
Aleocharini and Pinophilinit. The variations of this 


Staphylinide of the Amazon Valley, 33 


structure in certain groups are, however, so creat, that 
they must be examined in a very careful manner, from 
species to species, before any trustworthy generalizations 
can be established. Mr. Darwin, in his work on natural 
selection, has attempted to explain the meaning and im- 
portance of the extraordinary secondary sexual characters 
which are so striking in some species of insects 5 but I am 
strongly of opinion that an inquiry into the importance of 
secondary sexual characters must be preceded by a thorough 
investigation of the primary sexual characters, and after 
that is gained I think it probable we shall be better 
able to deal with the secondary characters. In the case of 
the vegetable kingdom, Mr. Darwin has himself shown, in 
a manner that has delighted all naturalists, how important 
and radical is the connection between the actual organs 
of reproduction and the accessory parts of the inflorescence ; 
and I think it highly probable that a similar course of 
inquiry, if carried out with insects, would make us ac- 
quainted with a direct connection between the primary 
and accessory sexual peculiarities. The difficulties in 
making the observations and dissections necessary in the 
prosecution of such researches is, however, very great in 
the case of organisms so small in size, and so complicated 
“n structure as are the great majority of the Insecta. 

Besides the enumeration and description of species with 
which this paper is chiefly occupied, there will be found 
prefixed to each genus some slight observations on dis- 
tribution, and on structural points, and a few critical 
remarks.

This genus was established by Fauvel (Notices Ento- 
mologiques, 4me part. p. 8), for a small beetle from Chili: 
and at the same time this savant established another 
genus (op. cit. p. 10) with the name Ophioglossa, for a 
closely allied insect from the same country. Some dif- 
ferences in the trophi (of which the most important is 
stated to be the labial palpi bi-articulate in Hudera, tri- 
articulate in Ophioglossa), and a slightly longer basal 
joint of the hind tarsus in Ophioglossa, are the only 
characteristics given to distinguish the two genera; more- 
over the hind tarsi are figured by the author, and on 
measuring with compasses the length of the basal joint in 
the two figures, I find it to be exactly the same: the 
distinction between the two genera rests therefore entirely 
on the trophi; and very unsatisfactory such a distinc- 
tion is in the case of two such minute insects. I feel 
considerable doubt, after examining a specimen of the 
insect L here describe under the name of Hudera cava, as 
to whether its labial palpi are bi-, or tri-articulate ; but 
as the Eudera sculptilis is known to me, and I am able to 
say that FZ. cava is certainly closely allied thereto, while I 
do not know the genus Ophioglossa, I have chosen the 
former name for the generic appellation of my new species. 
The species I here describe is very remarkable by reason 
of the extremely large and deep transverse impressions on 
the basal segments of the hind body; this character dis-

tinguishes it readily from its allies, viz., L. seulptilis and 
the species of Falagria and Autalia. 

It may not be amiss to remark here, that although 
M. Rey, in the recently published parts of the “ Histoire 
Naturelle des Coleoptéres de France,” has placed the two 
genera Autalia and Falagria in different primary divisions 
of the Aleocharide, still the two genera are really allied, 
as the Ludera sculptilis and cava ‘undoubtedly indicate. 


1. Eudera cava,n.sp. Rufescens, antennis basi excepto, 
capite, elytris, pectoreque obscurioribus; thorace elytris- 
que dense subtilissime punctatis, abdomine fere e impunctato, 
segmentis 2—4 basi profunde transversim impressis; 
thorace fortiter transverso, anterius obsolete impresso, basi 
transversim bifoveolato. Long. corp. 14 lin. 

Antenne short and stout, the basal joints reddish, the 
others obscure in colour; 3rd joint stout, a little shorter 
than 2nd; joints 4—10 similar to one another in length, 
and each distinctly broader than its predecessor, the “ath 
not so long as broad, the 10th strongly transverse; 11th 
joint pointed, as broad as, and more than twice as long as 
10th. Head nearly black, short and broad, with a narrow 
and remarkably : abrupt neck, with a transverse impression 
in front at the insertion of the antenne, the surface very 
finely, scarcely visibly, punctured. Thorax obscure red- 
dish, broader than the head, but narrower than the elytra, 
strongly transverse, the front angles rounded and de- 
pressed, the hind ones rectangular; on the middle, in 
front, is a small indistinct impression, and in the middle, 
in front of the base, is a kind of transverse impressed 
line, which is interrupted in the middle, and in certain 
lights appears to consist on each side of two or three 
very minute fovex placed extremely close to one another; 
the surface is very finely and closely punctured and 
pubescent. Elytra short and broad, longer than the 
thorax, the suture depressed at the base behind the 
scutellum ; their colour obscure castaneous, their punc- 
tuation very fine, and not so dense as that of the 
thorax. Hind body broad, above shining and flat; the 
2nd, 3rd and 4th segments each with a peculiar large deep 
transverse impression at the base; at each front angle of 
these impressions there is a kind of tubercle or projection. 
Legs rather short; middle cox widely separated. 

Para ; eight individuals taken two or three years ago; 
I notice no indications of sexual distinctions among them.

Obs.—A closely allied but distinct species occurs at 
Rio de Janeiro. 


FALAGRIA. 


The species of this widely distributed genus appear to 
be more numerous in tropical America than elsewhere ; 
23 species of the genus were described by Erichson, and 
of this number no less than 14 were from the quarter 
of the globe above mentioned. I here describe three new 
species, but I have no doubt numerous others are to be 
found in the Amazon valley. These three species are very 
dissimilar énter se; the F. Pare appears to be rather closely 
allied to the Eastern F. flavocincta, Ky., and F. fovea, 
Sharp; £. varicornis is remarkable not only from the 
great development and elegant colour of its antenne, 
but also from the point of insertion of these organs, this 
appearing to be actually nearer to the vertex than to the 
front margin of the head. #. curtipennis is a very pecu- 
liar species; its abbreviated elytra and breast, together 
with the slender and elongate limbs, give it a peculiar 
facies; and moreover the mesosternum shows no trace 
whatever of that division into distinct plates, which is so 
conspicuous in /’, obscura, and others of the genus ; it is, 
therefore, very probable that the species may ultimately 
be considered to belong to a distinct genus. 


1. Falagria Pare, n. sp. Rufescens, antennis medio 
infuscatis, basi cum pedibus testaceis, femoribus basi 
excepto fuscis, elytris abdomineque fuscis, illis humeris, 
hoc basi testaceis; capite thoraceque levis, nitidis, hoc 
profunde canaliculato ; abdomine dense subtilissime punc- 
tulato. Long. corp. 1} lin. 


Antenne rather stout, very nearly half a line in length ; 
the two or three basal joints pale reddish, the following 
ones infuscate; the 10th and 11th again reddish; 3rd 
joint shorter than 2nd; 4—10 differing very little from 
one another in length, each a little stouter than its prede- 
cessor ; the 10th about as long as broad; 11th scarcely 
broader than, but twice as long as the 10th, obtusely 
pointed. Head obscure reddish, shining, impunctate, with 
a transverse impression between the points of insertion 
of the antenne, its breadth about equal to the thorax. 
Thorax reddish, impunctate, with a deep channel along 
the middle, rather longer than broad, much narrowed 
towards the base. LElytra yellowish at the base, elsewhere 


_ 


42 Mr. D. Sharp’s Contributions to the 


infuscate, much broader than the thorax, but scarcely so 
long, with a small deep fovea behind the scutellum, ex- 
tremely finely—almost imperceptibly—punctured. Hind 
body slender, but distinctly narrowed at the base; blackish 
except at the base, which is yellowish, the segments very 
finely punctured. Legs yellow, the femora infuscate, 
except at the base ; the front ones however almost yellow. 

Para; a single indiy idual taken two or three years ago 
by Mr. Smith. 

Obs.—This species is smaller and more slenderly formed 
than our European F. suleatula, and the antenne are 
similar in structure to those of /. suleatula, but are not 
quite so much inerassate at the apex. 


2. Falagria varicornis, n. sp. Rufo-brunnea, nitida, 
fere laevis, antennis articulo ultimo, femoribus posticis basi, 
tarsis omnibus, abdomineque basi pallidis, hoe segmentis 
3—6 nigris; thorace subcordato, angulis posticis minutis, 
prominulis, late profundeque canaliculato; elytris hoc 
longioribus. Long. 14 lin. 


Of an obscure reddish colour, with the elytra rather 
darker; the hind body, with the exception of its pale base, 
nearly ‘black ; the legs and antenne variegated. The 
antenn are very long and reach beyond the “extremity of 
the elytra, they are reddish at the “base; the joints from 
the middle to the tenth get gradually darker, but the last 
joint is very pale, nearly. white; this joint is elongate and 
pointed, about the length of the three preceding together. 
The head is broader than the thorax, reddish, almost i im- 
punctate. The thorax is reddish, its length about as 
much as its greatest width. The posterior angles are very 
minute and pointed, and directed outwards ; it has a very 
broad and very deep longitudinal channel. The scutellum 
is delicately margined and furnished with two or three 
indistinct raised lines. The elytra are darker in colour 
than the head and thorax, very convex, depressed along 
the suture and round the scutellum, shining and almost 
glabrous. The hind body has the two basal seoments 
testaceous, the rest nearly black; the very extremity 
obscurely paler ; ; it is narrowed at the base, impunctate on 
the upper side, and only obscurely furnished with hairs. 
The legs are very long and slender, they are reddish-yel- 
low, the anterior with the tarsi paler, the middle ones 
have the base of the tibie darker, the apex as well as the 


Staphylinide of the Amazon Valley. 43 


tarsi pale ; the hind legs have the base of the femora pale, 
the rest as well as the tibiz pitchy ; but the extremity of 
the tibize and the tarsi are pale. 

Of this most elegant species I have seen but one speci- 
men, from Liga. 


3. Falagria curtipennis,n. sp. Flongata, rufo-testacea, 
nitida, fere levis, abdomine subdilatato, segmento quinto 
piceo. Long. 1} lin. 

This species has a peculiar aspect for this genus, owing 
to its elongate form, and its hind body being broader than 
the anterior parts. It is shining, of a yellowish colour, 
with the fifth segment of the hind body darker ; its upper 
surface is smooth, shining and impunctate; the under 
surface of the hind body is furnished towards the extre- 
mity with numerous hairs. The antenne are yellow, and 
reach quite to the extremity of the elytra; they are stout 
for this genus, and considerably thickened towards the 
apex; the 2nd, 3rd and 4th joints are slender and elon- 
gate, the 3rd a little longer than the 2nd, much longer 
than the 4th; from the 5th to the 10th each joint is a 
little broader than the preceding one, the 10th being 
about as long as broad; the 11th joint is pointed, about 
as broad as the 10th, but twice aslong. The head is quite 
smooth and shining, quite as broad as the thorax; the 
thorax is rather longer than its greatest breadth, convex, 
smooth and shining, with two or three set towards the 
sides; it 1s subcordate, with the anterior and posterior 
angles rounded; it is delicately margined at the sides 
and behind, without channel or fovea. The elytra are 
not so long as the thorax, and scarcely attain the width 
of its broadest part; they are just a little darker in colour, 
impunctate and shining, with a most delicate and spar- 
ing pubescence. The hind body is rounded at the sides; 
it is elongate and considerably broader in the middle than 
at the base and apex. ‘The legs are yellowish and elon- 
gate, the tarsi very slender. 

Several specimens from Tapajos. 

Obs.—A very closely allied species to this one occurs 
at Monte Video. 


PLACUSA. 


No species with this generic name has yet been indi- 
cated as inhabiting the New World; and the species I here 


- 
44 Mr. D. Sharp’s Contributions to the 


describe does not accord very closely in all its characters 
with our European species, as will be seen on comparing 
the observations I have made at the conclusion of the 
description of P. confinis with the generic characters of 
Placusa, as indicated by Rey (Hist. Nat. Col. Brey. 
Al. Bol. p- 103). I have not ascertained whether the 
labial palpi of this minute insect are two- or three-jointed. 


1. Placusa confinis, n. sp.  Angustula, subopaca, 
nigricans, antennarum articulo primo, pedibus elytrisque 
sordide testaceis, his basi J SPE ESS fuscis ; supra crebre 
subtiliterque punctata. Long. corp. { lin. 


Antenne short, rather slender, planet with the base 
indistinctly paler; 3rd joint small, much shorter than 
2nd; 4th and 5th smaller than those following; 6—10 
differing but little from one another, transverse; 11th small. 
Head small, a good deal narrower than the thorax, 
blackish, finely and not densely punctured. Thorax 
small, rather strongly transverse, the base rounded, and 
not perceptibly sinuate, the hind angles very indistinct, the 
sides distinctly narrowed towards the front; it is blackish 
in colour, finely and not densely punctured, so as to be a 
little shining. Elytra short but a little longer than the 
thorax, blackish at the base and sides, shading into yellow 
towards the extremity, rather finely and closely punctured. 
Hind body narrow, pointed, all the segments finely and 
closely punctured, but still slightly shming. Legs yellow. 

In the male the hind margin of the dorsal plate of the 
7th segment of the hind body projects a little on each side of 
the middle, so as to form two very short, obtuse, distant 
projections, which are not long enough to be called 
teeth. 

A pair of this species, ¢ and ?, were found at Lagos, 
on the 5th January, 1875, by Dr. Trail. 

Obs.—This species, though it has quite the facies of 
our European Placuse, is narrower than any one of them 
I am acquainted with. The middle coxe are quite conti- 
guous, and the middle portion of the front of the metaster- 
num is less acuminate than in the European species ; the 
basal joint of the 4-jointed middle tarsi is distinctly longer 
than the 2nd, but not nearly so long as the 2nd and 3rd 
together ; and the basal joint of the hind tarsus, though 
more elongate than that of the middle ones, is not so long 
as the 2nd and 3rd together. 


Staphylinide of the Amazon Valley. 45 


EPIPEDA. 


This genus has recently been established and named by 
_ Rey, to express the Aleochara plana, Gyll., and Homalota 
arcana, Er. The first of these species (the second I do 
not know) certainly cannot be associated with the Homa- 
lote, on account of the 4-jointed intermediate tarsi; and 
it appears to me probable that Rey is correct im placing 
Epipeda near Placusa. The two species of the genus 
here described, depart somewhat in their structure from the 
Aleochara plana, and apparently approximate to Diestota. 
Indeed the relationship of Diestota with Epipeda seems to 
me to be probably (for I do not know the D. Mayet?) much 
closer than is suggested by Rey, who places the two 
genera in different “rameaux,” on account of the separation 
of the middle coxe in the one (Diéestota) and their conti- 
guity in the other (Epipeda); it is precisely in this cha- 
racter that the two species, here described as Epipeda, 
depart from the European species of the genus, and appear 
to exhibit the connecting links with Diestota. I may add 
that Dr. Trail also brought back an insect which I can 
scarcely class with either of the two genera, for the middle 
coxee are widely separated, while the gene are very 
strongly margined. I have unfortunately not been able 
to describe this interesting species, as the only exponent 
of it I have received has lost its elytra. 


1. Epipeda cava, n. sp. Linearis, subdepressa, opaca, 
nigro-fusca, antennarum articulo primo pedibusque testa- 
ceis; prothorace subquadrato, medio late, profundeque 
impresso; abdomine segmentis 2—4 crebre subtiliter 
punctatis, 5 et 6 fere impunctatis. Long. 1 ln. 


Allied to Homolata plana, but smaller, and with much 
longer antenne. These are longer than head and thorax, 
pitchy in colour, with the base paler; they are moderately 
stout, and scarcely thickened towards the apex ; 3rd joint 
more slender than the 2nd, and scarcely so long ; 4—10 
differing but little from one another; 4th longer than 
broad, 10th scarcely so long as it is broad; last joint elon- 
gate, quite twice as long as the two preceding together. 
Head a little narrower than the thorax, formed as in 
H. plana, the front a little depressed; it is of a dark 
colour, quite dull, punctuation quite indistinct. Thorax 
about a third broader than long, shaped much as in H. 
plana, dull, its punctuation very dense and indistinct, of a 


i

dark fuscous colour in the middle, with a very broad and 
deep impression, occupying the whole of the middle por- 
tion of the thorax. Elytra but little longer than the 
thorax, of the same colour, and with similar punctua- 
tion. Hind body shaped much as in //. plana, segments 
2—4 rather closely and finely punctured, 5th sparingly 
punctured, 6th nearly impunctate. Legs yellowish. 

St. Paulo (Amazons); one specimen. I think it is a 
male; if so, it has no well marked peculiarity as such, un- 
less the very large impression of the thorax be characteris- 
tic of this sex, as is quite probable. 

Obs.—Though much smaller than the European Epi- 
peda plana, this species appears to be structurally closely 
allied thereto; the middle cox are however slightly more 
widely separated, so that the meso- and meta-sternal pro- 
cesses are rather less slender and acuminate in /. cava. 


2. Epipeda rufa, n. sp. Angustula, depressa, dense 
punctata, rufescens, antennis extrorsum, abdomine pec- 
toreque infuscatis, elytris pedibusque testaceis ; prothorace 
subquadrato, angulis posterioribus obtuse rectis. Long. 
corp. % lin. 

Antennz moderately long, not stout, scarcely at all 
thickened towards the extremity, the two or three basal 
joints reddish, the rest darker ; 2nd joint about as stout as 
the lst; 3rd shorter than 2nd; 4th smaller than the 
others ; 5—10 differing but little from one another; 11th 
moderately long. Head rather narrow, a good deal nar- 
rower than the thorax, distinctly narrowed behind the 
eyes, infuscate reddish, not at all shining, closely and finely 
punctured. Thorax slightly narrower than the elytra, 
almost as long as broad, somewhat straight at the sides, 
being only a little narrowed behind, and but little rounded 
near the front angles, the hind angles not at all rounded but 
distinctly obtuse ; dull reddish in colour, finely and closely 
punctured, quite dull, longitudinally depressed along the 
middle. LElytra rather elongate, a good deal longer than 
the thorax, yellow, closely and finely punctured. Hind 
body parallel, all the segments closely, finely and evenly 
punctured, infuscate reddish, with the extremity paler. 
Legs, including the coxe, clear yellow ; metasternum in- 
fuscate at the sides, reddish in the middle. 

Ega; two individuals in which I see no sexual cha- 
racters. 

Obs.—In this species the middle coxze are quite sepa-

rated, the mesosternal process is elongate, truncate at the 
extremity and meets the middle process of the metaster- 
num. The middle tarsi are 4-, the hinder 5-jointed. The 
gen are not margined. 


DIESTOTA. 


This genus has been recently established by Rey, for 
a minute beetle found at Cette, in flowers of Cistus: and 
it is moreover considered by the French author to form of 
itself a distinct rameau of his branch Bolitocharaires. I 
am not acquainted with this French insect, and I cannot 
therefore speak in an unhesitating manner as to the close 
affinity therewith of the species here described ; but so far 
as I can judge the two form really part of one genus. 
The relationship of Diestota with Epipeda seems to me to 
be closer than supposed by M. Rey; and the two species 
of the latter genus here described, indicate this affinity in 
a still more certain manner than does the European Aleo- 
chara plana (Epipeda, Rey). 

Rey describes Diestota Mayeti as possessing a “sensible” 
margin to the gene, but I cannot see any trace of such 
raised margin in D, sperata. I may also add, that trusting 
to my memory, I believe the insect described by me 
(Trans. Ent. Soc. Lond. 1869, p. 166) as Homalota cri- 
briceps, will be found to belong to this genus; and further, 
that I think it highly probable that Déestota will prove to 
be synonymous with Cenonica, Kr. 


1. Diestota sperata,n. sp. Parallela, subdepressa, fusca, 
prothorace dilutiore ; abdomine pedibusque testaceis, illo

Antenne rather slender, moderately long, only slightly 
thickened towards the apex; the three basal joints elon-

than Sth, about as long as broad; 5—10 each of about 
the same length; the 5th about as long as broad; the 10th 
distinctly transverse; 11th joint elongate, longer than the 
two preceding together ; their colour is smoky black, with 
the base a little paler. Head narrower than the thorax, 
short and broad, but much narrowed behind, closely and 
finely punctured, not shining, fuscous in colour, with the 
parts of the mouth obscure yellow. Thorax a little nar-

rower than the elytra, strongly transverse, nearly twice as 
broad as long; the sides sinuate and narrowed behind; the 
hind angles obtuse but not rounded, with a transverse 
impression at the base in the middle, infuscate red, very 
closely and very finely punctured, quite dull. LElytra a 
good deal longer than the thorax, very closely and finely 
punctured, quite dull, in colour darker than the thorax, 
but similar to the head ; their hind margin a little sinuate 
at the outer angles. Hind body parallel, obscure yellowish 
in colour; the Sth and 6th segments infuscate, the extre- 
mity not so pale as the base; the basal segments are 
closely and finely punctured, the apical ones sparingly 
punctured so that they are less opaque than the rest of the 
upper surface. Legs, including the cox, clear yellow. 

In the male the hind margin of the dorsal plate of the 
7th segment of the hind body terminates in six slender 
teeth; the four middle ones are equidistant, and each 
one of them is a little thickened at the extremity, the out- 
side one (on each side) is slightly longer than the middle 
ones, and is pointed, and is separated from the middle 
ones by a broader space than divides them from one 
another. 

Rio Purus, Amazons; six specimens found by Dr. 
Trail on the 13th October, 1874. 

Obs.—This species appears to vary somewhat in colour 
and size; and the above description is made from one of 
the largest and most brightly coloured individuals. 


BRACHIDA. 


This genus has recently been established by M. Rey, 
in the “ Histoire Naturelle des Coleoptéres de France,”* 
(Brevipennes, Aleochariens), for the European Homalota 
notha. The 4-jointed intermediate tarsi, and the struc- 
ture of the meso- and meta-sterna, fully justify this course, 
and prove that the relationship of H/. notha to other 
Homalote is only remote. I here describe two species 
which must be ascribed to Rey’s genus Brachida, and I 
have other allied South American species in my collection. 


* It is to be regretted that the volumes of this work are not numbered; 
four or five different parts each with separate pagination, and indices, bear 
the above title (Brevipennes, Aléochariens), and detailed reference to the 
work is not easy. It is true that one might use the year of publication 
for the purpose, but this is sometimes erroneously indicated on the title 
page, and sometimes more than one part has been published in the same 
year.

Allied to Homalota notha, but larger and brighter in 
colour, and even more like a Gyrophena, by its deflexed 
head, and curled-up hind body; the colouration is also very 
much that of a Gyrophena. The antenne are rather 
short, considerably thickened towards the apex; the 3rd 
joimt is more short and more slender than the 2nd ; the 
4th joint is but little stouter than the 3rd, and not quite 
so long—from this to the 10th each joint is stouter than 
the preceding one; 5th longer than broad; 10th evidently 
transverse; 11th joint rather thick, nearly twice as long 
as the 10th, and rather lighter in colour. Head deflexed, 
narrower than the thorax, pitchy, very finely and indis- 
tinctly punctured. Thorax very short, shaped like that of 
a Gyrophena, rather narrower than the elytra, more 
than twice as broad as long, all the angles much rounded ; 
of a pitchy ferruginous colour, almost impunctate. Elytra 
longer than the thorax, of a tawny colour, a little darker 
at the external angle, rather closely covered with fine 
elevated punctures, ‘vhich are not so distinct about the 
seutellum. Hind body yellowish, a little darker towards 
the apex; rather rounded at the sides, narrower at the 
extremity; shining above, and nearly impunctate, but to- 
wards the extremity the segments are furnished with some 
very fine elevated points; it is clothed on the underside 
with a dense, fine, erect pubescence. The legs are yellow. 

In the male the elytra are provided, near the outer 
corner, with an elevated tubercle, and the 6th and 7th 
segments of the hind body are furnished on the upper side 
with numerous granulations, which are coarser on the 7th 
than on the 6th segment.

Antenne slender, scarcely thickened towards the extre- 
mity, yellowish, with joints 5—10 nearly black, each joint 
longer than broad. Head infuseate, very indistinctly 
punctured, but with a distinct pubescence. Thorax ob- 
secure reddish, scarcely visibly punctured, but with a 
delicate, distinct pubescence ; the front angles depressed 
and rounded, the sides scarcely curved; the hind angles 
obtuse, the base rounded, very slightly emarginate in front 
of the scutellum. Elytra a good | deal longer, and slightly 
broader than the thorax, infuscate- red, with the shoulders 
paler, their punctuation close and fine, but more visible 
than on the other parts of the surface; the extremity only 
obsoletely sinuate near the outer angle. Hind body much 
narrowed towards the extremity, reddish, with the 4th, 
5th and 6th segments infuscate, the apex yellowish ; the 
dorsal segments very finely punctured and _ pubescent. 
Legs yellowish, rather long and slender. 

The male shows no marked external sexual characters ; 
the hind margin of the dorsal plate of the 8th segment is 
almost truncate, being only very slightly emarginate. In 
the female the hind margin of the dorsal plate of the 8th 
segment is deeply emarginate; and the same plate shows, 
at the extreme base on each side, a deep transverse fovea 
of which there is no trace in the male. 

Para; several specimens taken two or three years ago. 

Obs.—A variety occurs in the same locality; it is 
almost unicolorous reddish, except the middle of the 
antenne.

The curious insect for which I propose this generic 
name is one of the most remarkable of the Staphylinide 
found by Mr. Bates. Unfortunately I have seen but a 
single individual, so that I am able to give its characters 
in only an incomplete manner. The head is small, de- 
flexed, and much embraced by the angles of the thorax, so 
that I have been quite unable to see the parts of the 
mouth ; and although I have made a careful examination 
with the compound microscope, I do not feel quite sure 
that the front tarsi may not have a minute basal joint. I 
cannot pronounce on its exact position a confident opinion, 
but I believe it will ultimately be found allied to Dinarda, 
possibly making an approach from that genus to the won- 
derful Corotoca of Schiddte. 

Rey has recently considered the genus Dinarda as 
forming of itself one of the eight primary divisions of the 
Aleocharide ; this isolated position he assigns to it in 
consequence of the elytra being compressed and carinated 
at the sides, which is the case so far as he knows with no 
other Aleocharide. The Myrmigaster singularis shows, 
however, no trace of this peculiarity; I myself consider 
this character to be quite insufficient of itself to justify the 
prominent isolation given to the two species of Dinarda 
by the learned Frenchman, who actually makes, of the two 
species of Dinarda, the first branch (branche, Dinar- 
daires) of the Aleocharide.

Antenne formed as in the genus Dinarda, but much 
more slender, and with their exserted setz longer; the 
joints are closely packed, so that the divisions between 
them are not striking; the Ist joint stouter and longer 
than the 2nd; the 2nd and 3rd small, the 2nd being the 
longer of the two; from the 4th to the 10th each joint is 
but slightly stouter than the foregoing one; the 10th

about as long as broad; the terminal joint not broader 
than the 10th, pointed, about as long as the two sane 
ones together. The head and thorax are of a pitchy or < 
pitchy-red colour, covered, as are also the elytra, with heck, 
stout, erect sete. Thorax a little broader ‘than the elytra, 
more than twice as broad as long, much narrower in front 
than behind, its middle part a little elevated, the sides de- 
flexed, the middle of the base a little produced in front of the 
scutellum, the posterior angles acute and projecting back- 
wards. The elytra are rather lighter in colour than the 
thorax, and about one-third longer; they are narrower 
at the apex and the base; under the microscope the 
sculpture of the thorax and elytra is seen to consist of 
small round smooth spots, between which the surface is 
coriaceous. The abdomen is much narrower than the 
thorax; it is nearly impunctate, and very finely pubescent, 
but the basal segments are also furnished with sete finer 
than those of the thorax and elytra: it is very convex 
above and below, and the first visible segment is much 
narrowed all round from its apex to its base. 

Ega; a single individual, which I suspect to be a male. 


MyRMEDONIA., 


Of this widely distributed genus, nine or ten species 
have been already described from tropical America: to 
this number I now add other six species. Of these six 
species, the first five are pretty closely allied to one 
another, while the sixth (viz., Mf. nitidula) is very dis- 
tinct. Rey has recently divided the genus Myrmedonia 
into a number of different genera, distributed among two 
distinct branches, Myrmédoniates, and Myrméciates. If 
this arrangement were adopted, then MM. scabripennis, M. 
pollens, M. Batesi, M. spinifer, and M. fortunata, would 
belong to the branch Myrmédoniates, and to Rey’s genus 
Zyras, or more probably to a distinct new genus to be 
placed at the head of the branch: while M. nitidula 
would have to form a distinct branch intermediate be- 
tween the Myrmédoniates and Myrméciates. 1 do not, 
however, adopt this classification; for while I thoroughly 
appreciate the great addition M. Rey’s labours have made 
to our knowledge, I am quite convinced that the attempt 
to found new and complicated classifications on the insects 
of a single country must prove abortive; and probably 
worse than useless when applied to the insects of the 


Staphylinide of the Amazon Valley. 53 


world at large. Without therefore adopting Rey’s names, 
I prefer to point out that the first five species here de- 
scribed are allied to our Myrmedonia Haworthi, but are 
remarkable by the great development of the spurs at the 
extremities of the tibie. I. nitidula, on the other hand, 
is very distinct on account of the basal joint of the inter- 
mediate tarsus, which is only as long as the 2nd joint, 
while the basal joint of the hind tarsus is only a little 
longer than the following one; and the spurs at the 
extremity of the tibia are much less developed. It is only 
when our knowledge of these insects is much more ad- 
vanced than it is at present, that we shall be able to point 
out with something like certainty what we may hope will 
prove stable generic characters.

Antenne longer than the head and thorax; slender, 
scarcely thickened towards the apex, pitchy, paler at the 
base ; 3rd joint elongate, quite twice as long as the 2nd; 
4th shorter than 3rd, but considerably longer than the 
5th; 10th about as long as broad ; 11th pointed, twice as 
long as the 10th. Head black, shining, strongly punc- 
tured, with a narrow smooth space in the middle. Thorax 
about as long as broad, scarcely narrowed behind, the 
base rounded, the hind angles very obtuse, the front ones 
deflexed and rounded; very strongly and closely, but not 
deeply, punctured, with a transverse impression in front of 
the scutellum, and two irregular, not very distinct, smooth 
spaces on each side near the front (placed one behind the 
other); on each side it is broadly impressed at the sides 
behind. ‘The elytra are about as long as the thorax, 
and nearly twice as broad; more than twice as broad as 
the head; black, not shining, densely scabrous. Hind 
body pitchy, shining, narrowed behind ; the margins large, 
and much turned upwards; impunctate, and shining above;

very convex on the under surface, and there closely and 
distinctly punctured. The legs are pale yellow, the 
femora pitchy on their hind margin; the hind tarsi long 
and slender; their basal joint, though not quite so long as 
the other four together, is longer than the three following 
taken together. 

In the male the second segment of the hind body has 
on the upper side three long spines, reaching about to the 
extremity of the next seoment, the middle one not quite 
so long as the side ones; the third segment has its hind 
margin a little emarginate ; the sixth segment has an ele- 
vation near each side extending from the base to the 
extremity, between these it is a little impressed, and 
immediately in front of the hind margin is furnished with 
four or five small asperities; the seventh segment is 
covered above with similar asperities, and is longitudinal y 
elevated or swollen in the middle. 

Ega; one male.

The single specimen before me of this species is clearly 
immature, so that I shall not give details of its colouring 
further than to say, that it is of a pitchy colour, with the 
basal portion of the antennee and the legs (more particu- 
larly the femora) paler. Antenne with the 3rd joint 
about twice as long as the 2nd, and one and a-half times 
the length of the “4th ; 5th much shorter than the 4th, 
longer than broad; 6—10 differing but little in length; 
the 10th scarcely so long as broad; last joint pointed, 
about twice as long as the 10th. The head -is closely 
and rather coarsely punctured, with a smooth shining 
space in the middle. The thorax is about as long as 
broad, with a distinct longitudinal channel; scarcely nar- 
rowed behind; the sides nearly straight from the front 
to the hind angles ; it is moderately finely and very 
closely punctured, so that it is not at all shining. The 
elytra are about as long as the thorax and one and a-half 
times its width, their punctuation extremely close, and 
finer than that of the thorax, quite dull. The hind body 
is shining above, and obsoletely but distinctly punctured,

the punctuation being less evident on the apical segments. 
Beneath it is closely and distinctly punctured. The basal 
joint of the posterior tarsus about as long as the three 
following together. 

In the female the 6th segment above has a longitudinal 
elevation on each side; the 7th segment is covered with 
eranulations not much elevated, but with their points 
directed backwards; these granulations are larger towards 
the extremity of the segment, and the hind margin 1S 
slightly emarginate. 

Ega; one specimen, which I consider to be a female. 

Obs.—Though rather closely allied to M. scabripennis, 
M. pollens will be very readily distinguished therefrom by 
the denser and finer punctuation of the thorax and elytra, 
and by the less uneven surface of the thorax.

Antenne moderately long and slender, pitchy, paler at 
the base; 3rd joint twice as long as the 2nd ; Ath shorter 
than the 3rd, twice as long as the 5th; 5—10 each a 
little shorter and a little broader than the preceding one, 
5th about as long as broad, 10th with the breadth greater 
than the length; 11th pointed, quite twice as long as the 
10th. Head black and shining; front punctured on each 
side, smooth in the middle. Thorax black, its breadth 
one and a third times its length, scarcely narrowed behind ; 
the base rounded; the posterior angles extremely obtuse, 
the anterior rounded and deflexed; its upper surface 
strongly punctured and uneven, with an impression in 
front of the scutellum, and with an indistinct longitudinal 
channel, and a large ill-defined impression on each side, 
reaching from the posterior angles nearly to the front. 
Elytra about as long as the thorax, reddish, but all the 
hind part smoky black, densely and finely scabrous, punc- 
tate, more strongly so near the suture behind. Hind body 
pitchy, with the margins of the segments paler, narrowed 
behind, and with the basal segment a little constricted, 
smooth, shining and impunctate above, finely and closely 
punctured below ; the side margins of the segments much

tarsus about as long as the three succeeding together. 

In the female the upper side of the sixth segment has 
an indistinct longitudinal elevation (or two) on each side, 
and also some scattered fine asperities, with their points 
directed backwards; the 7th segment is covered above 
with similar, but larger and more numerous, asperities, 
and its hind margin is irregularly serrate; the teeth six or 
eight in number; the lateral margins of these two seg- 
ments are also indistinctly serrate.

Fem. abdomine simplice. 


Antenne rather long and stout, reddish-yellow, infus- 
cated towards the apex; 3rd joint quite twice as long as 
the 2nd, one and a-half times the length of the 4th; from 
5—10 each joint is a little shorter than the preceding, 
the 5th more than half the length of the 4th, much longer 
than broad, the 10th about as long as broad; the 11th 
joint pointed, quite twice as long as the 10th. Head 
black and shining, strongly punctured, but with a smooth 
space in the middle. Thorax shining, yellowish, about 
as long as broad, the sides a little dilated in front; the 
posterior angles extremely obtuse, with a fovea in front 
of the scutellum, and an indistict impression on each side 
behind, covered with large but little-impressed punctures ; 
these punctures nearly disappear in front, and are quite 
absent at the anterior angles. The elytra are about as 
long as the thorax and nearly twice as broad, reddish- 
yellow, with a black spot on the external margin behind, 
densely covered with coarse asperities or elevations. The 
hind body is yellowish, marked much with black in the

lateral margins broad and turned, outwards as well as 
upwards. The legs are yellowish; the basal joint of the 
posterior tarsus about as long asthe three following together. 
In the male the 2nd segment is armed in the middle with a 
long sharp spine, about as long as the segment itself; the 
lateral mar gins of the seoments are detached and acumi- 
nated behind, but not produced into spines (as they are in 
M. scabripennis) ; the 6th segment is furnished with a 
longitudinal plica on each side, and has two tubercles a 
little before the hind margin. The 7th segment is 
thickly covered with rather fine granulations, and has a 
larger tubercle on the middle; its hind margin is obscurely 
serrated and has a shallow notch in the middle. In the 
female the 2nd segment is simple and the tubercle of the 
7th segment is absent. 
Ega; three individuals,—two male, one female.

slightly stouter than its predecessor; 11th rather stouter 
than the 10th, but not quite so long. Head blackish, 
shining, very coarsely punctured. Thorax yellowish, about 
as long as broad, slightly narrowed behind, very coarsely 
punctured, obsoletely depressed on each side the disc. The 
elytra yellowish, infuscate about the apical angle, scarcely 
so long as the thorax but much broader, closely and mode-

In this species the sculpture of the elytra consists of 
true impressions closely packed, so that the interstices 
appear like rough irregularly waved lines.

A shining unicolorous species, with the head and thorax 
small in proportion to the hind body. Antenne mode- 
rately long, a little thickened towards the extremity, their 
pubescence well marked; 3rd joint a little longer and 
rather more slender than the 2nd; 4th joint sniall, about 
half the length of the 3rd, and rather smaller than the 
5th; 5—10 each is a little shorter and broader than its 
predecessor, each much narrowed to its base, 5th conside- 
rably longer than broad, 10th not so long as broad; 11th 
joint pointed, fully as stout as the 10th and twice as long. 
The head is but little narrower than the thorax, shining 
and impunctate. The thorax is convex, ie bro ader 
than long, not at all narrowed behind, the sides being 
straight, with the anterior and posterior angles rounded ; 
it has a few elev ated punctures, from each of which springs 
a fine short hair. ‘The elytra are about as long as, but 
much broader than the thorax, a little narrowed at the 
shoulders; sparingly punctured, the points consisting of 
very slight elevations, from each of which rises a fine 
but rather long hair. The hind body is entirely smooth, 
shining, and impunctate above; it has the margin much 
developed, and directed outwards as well as upwards ; 
beneath it is finely and sparingly punctured and very deli- 
cately pubescent. The legs are yellowish, the tibiae much 
ciliated, the basal joint of the hind tarsi not greatly longer 
than the second. 

The male has on the upper side of the 6th segment four 
slight raised lines, more distinct at their termination; a 
little before the extremity of the sezment, between these 
lines, are numerous very fine, closely packed, indistinct 
ines: ; the hind margin of the 7th segment is serrate, and 
in front of the margin are some longitudinal eranulations.

CALODERA. 


The insect to which I have given this generic name is 
one which, in relation to our Kuropean species, must be 
considered very anomalous. ‘The tarsi are all 5-jointed ; 
the head is distinctly constricted behind; the antennz are 
elongate, and the basal joint of the hind tarsi, though 
moderately elongate, is not equal to the two following 
together; the middle cox are rather widely separated, 
the suture between the meta- and meso-sterna being near 
the front of the cox, and nearly straight. The insect, 
therefore, is intermediate between Rey’s two rameaux of the 
Aléocharaires, which he names Phleoparates and Calode- 
rates. I have made use of the generic name Calodera 
rather than Phleopora, because the latter is used only in a 
restricted sense— that is, for a few species closely resem- 
bling one another—while Calodera is a very elastic and 
general term, applied to a number of insects with very 
different facies, and varying much in structure. 


1. Calodera syntheta, n. sp. Capite thoraceque fuscis, 
elytris fusco-testaceis, basi dilutiore, abdomine medio apice-

Antenne elongate, rather slender, but a little incrassate 
towards the extremity, the three or four basal joints pale 
yellow, the following ones darker, and the three or four 
apical ones strongly infuscate; 3rd joint slightly longer 
than 2nd; 4th slender and rather long; 10th about as long 
as broad ; 11th joint elongate, about as long as the three 
preceding joints together, acuminate, its apex rather paler 
in colour than its base. Head about as broad as the 
thorax, narrowed behind, with a moderately broad neck ; 
the eyes large, the gene not margined; blackish in colour, 
finely punctured, a little shining. Thorax not quite 
so long as broad, narrower than the elytra, the sides 
much rounded at the front angles, narrowed and sinuate 
towards the base, which is rounded; the lateral and basal 
margins distinct, the hind angles depressed, but a little 
prominent, and rather obtuse; the colour is deeply infus- 
cate-yellow ; the surface indistinctly and not densely punc- 
tured, without channel or fovea. Scutellum large; elytra

HoMALora. 


It would not be easy at the present moment to say what 
the above word represents: to Erichson and Kraatz it 
represented a vast number of species of minute Staphyl- 
nide ; to C. J. Thomson a single species, viz. Aleochara 
plana, Gyll.; while to Rey it appears to have two different 
and yet simultaneous meanings; first, as representing 
about forty-five species of French Aleocharide, and the 
second, with the affix ‘“ vera,” as representing only ten of 
those forty-five species. 

As to the species here described, I use the word in the 
general sense of IXraatz and E richson ; for the first five of 
the six species here described would no doubt have been 
referred by those authors to the genus Homalota; the 
other species, however, //. culpa, is anomalous, inas- 
much as the basal joint of the hind tarsus is more clongate 
than is supposed to be the case with Homalota: but, as in 
the present state of confusion as to the nomenclature of 
the groups of species of Aleocharide, I decline to be 
responsible for a new generic name, I have had no option 
but to refer this as well as the other species to the genus 
Homalota.

different from one another in length, but the 4th not more 
than half as broad as the 10th; this latter as well as the 
preceding joints strongly transverse ; 11th jot moderately 
long, quite as long as the two preceding together. Head 
short and broad, but distinctly narrower than the thorax, 
black, very finely punctured, the punctures absent from 
a longitudinal space on the middle, and the hinder part 
slightly impressed on the middle. Thorax almost as broad 
as the elytra, twice as broad as long, very finely and 
moderately closely punctured, with a shght depression on 
the dise. Elytra a good deal longer than the thorax, 
finely and moderately closely punctured. Hind body dis- 
tinctly narrowed towards the extremity, the basal seg- 
ments finely and rather closely, the apical ones sparingly 
punctured. Legs yellow, but a little infuscate. 

In the male, the hind margin of the dorsal plate of the 
7th segment of the hind body is furnished in the middle 
with three rather approximate, equidistant, similar spines, 
and on each side with an extremely long, slender, pointed 
spine, which is a little incurved. 

A single male was found by Dr. Trail at Barreiras de 
Janarape, Rio Solimoes, on the 9th January, 1875. 

Obs.—This species has the middle tarsi 5-jointed ; the 
middle cox are distinctly separated, the meso- and meta- 
sternal processes both acuminate, and meeting one another 
about half-way between the coxze; the genx appear to me 
to be very finely margined. It much resembles the 
European 7. indiscreta, Sharp, but is decidedly smaller, 
and has the male characters very different.

verse; llth joint rather elongate, fully twice as long as 
the 10th. Head short and broad, finely and not densely 
punctured, nearly black. Thorax a little narrower than 
the elytra, broader than long, slightly rounded at the sides

and a little narrowed towards the front, the base much 
rounded, the hind angles quite indistinct; it is rather 
paler in colour than the head and elytra, finely and not 
closely punctured. The elytra are distinctly longer than 
the thorax, but their punctuation is similar to it; their 
hind margin is not sinuate. Hind body with the basal 
segments ” distinctly and not densely, the apical one 
sparingly punctured; the three basal segments reddish, 
the others darker. Legs yellow. 

In the male, the hind margin of the dorsal plate of the 
7th segment of the hind body has in the middle a long 
and broad projection which is divided in the middle, each 
side being rounded, while at each side the hind margin 
terminates in a long, slender, pointed and incurved spine, 
which projects fully as far backwards as the central 
process. 

Barreiras de Janarape, 9th January, 1875, a single 
male brought back by Dr. Trail. 

Obs.—Though much smaller, this species is somewhat 
similar to 7. fungicola, particularly i in the structure of its 
antenne. The gen are very finely margined, the middle 
cox distinctly separated, the mesosternal process much 
produced between them.

Antenne stout, the three or four basal joints pale 
yellow, the others infuscate; 3rd joint more slender and 
‘ather shorter than 2nd; 4—10 about equal to one another 
in length, each a little broader than its predecessor, 
the 4th about as long as broad, the penultimate ones 
transverse; 11th broad, quite as long as the two preceding 
together. Head broad and short, but a good deal nar- 
rower than the thorax, the eyes occupying nearly all the 
sides; blackish in colour, finely punctured. Thorax dis- 
tinetly narrower than the elytra, strongly transverse, the 
base much rounded, but a little truncate in front of the 
scutellum, the hind angles indistinct ; it is yellowish in 
colour, finely punctured, without channel or impression. 
Elytra broad, longer than the thorax ; black with a violet 
tinge, closely and | finely punctured, their hind margin not 


at all sinuate at the outer angles. Hind body broad and

short; the three or four basal segments yellow; the fol- 
lowing three abruptly black, the extremity infuscate- 
yellow; the segments are finely and rather closely punc- 
tured, the apical ones not so densely, however, as the 
basal ones. The legs, including the cox, are pale 
yellow. 

Garrao; five individuals found in fungus by Dr. Trail 
on the 11th November, 1874. I see no indications of 
external sexual characters. 

Obs.—This species is similar in size and form to our 
European H. celata, but the colouration is rather that of 
Gyrophene. The gene are finely margined; the middle 
cox quite separated ; the metasternum is much produced 
between them, and is separated only by a narrow space 
from the extremity of the mesosternal process, the extre- 
mities of both processes being rounded; the middle tarsi 
are 5-jointed, the basal joint a little longer than the 2nd; 
2—4 about equal to one another ; hind tarsi with the 2nd 
joint a little shorter than the 1st, and the 3rd a little 
shorter than the 2nd, slightly longer than the 4th. 


4. Homalata gilva, n. sp. Testacea, elytris abdo- 
mineque cingulo ante apicem nigricantibus; prothorace 
transverso, basi rotundato; abdomine basi crebre subtiliter, 
apice parce punctato. Long. corp. @ lin. 


Antennx moderately long and stout, yellow; 3rd joint 
shorter and more slender than 2nd; 4th joint very small; 
5th a good deal larger than 4th; 6—10 each slightly 
shorter and broader than its predecessor, the 6th about as 
long as broad, the 10th rather strongly transverse ; 11th 
joint large, longer than the two preceding ones together. 
Head short and broad, a good deal narrower than the 
thorax ; dark yellow, very finely punctured, not shining ; 
the eyes large. Thorax strongly transverse, nearly as 
broad as the elytra, the sides slightly narrowed behind, the 
base much rounded; it is yellow in colour, not at all 
shining, very finely punctured, without channel or fovea. 
Elytra short, but a little longer than thorax, infuscate ; 
the base paler, finely and closely punctured, quite dull ; 
the hind margin straight. Hind body yellow, with the 
5th segment black; the basal segments finely punctured, 
the sixth nearly impunctate. Legs pale yellow. 

In the male the dorsal plate of the 7th segment of the 
hind body is deeply emarginate on each side, so as to form 


64 Mr. D. Sharp’s Contributions to the 


a large central lobe, and on each side a projecting spine ; 
the central lobe is itself emarginate at the hind margin, 
and its angles are quite rounded ; the lateral spine on each 
side is pointed, and very nearly straight, and does not 
extend quite so far backward as the most prominent part 
of the central lobe. 

Garrao; a single male, found with JZ. brevis. 

Obs. I—The middle tarsi in this species are 5-jointed, 
the two basal joints being short, and similar to one another 
in length; the four basal joints of the hind tarsus also differ 
but little from one another in length; the middle cox are 
distinctly separated; the apices of the meso- and meta- 
sternal processes are rounded and widely separated from 
one another by a black space. 

Obs. I1.—This species is smaller and narrower than 
H. brevis, to which it bears a considerable resemblance ; 
the antennz are rather more slender, and the hind body 
less densely punctured. The individual described is per- 
haps immature. 


5. Homalota Traili, n. sp. Testacea, capite, elytris, 
pectore, abdomineque cingulo ante apicem infuscatis ; 
antennis fuscis, basi apiceque testaceis; prothorace trans- 
verso, medio indistincte impresso; abdomine basi sat 
erebre, apice parce, punctato. Long. corp. { lin. 


Antenne rather stout, only moderately long, the two or 
three basal joints obscure yellow, the following ones infus- 
cate, the 11th clear yellow; 3rd joint slender at base, but 
broad at apex, almost equal to 2nd joint in length and 
breadth; 4th not shorter and only slightly narrower than 
5th, hardly so long as broad; 5—10 differing but little from 
one another, each transvers e, the 10th more strongly so 
than the 5th; 11th joint rather elongate, quite as long as 
the two preceding together. Head broad and short, “the 
eyes moderately large, infuscate-yellow, finely punctured, 
with the vertex depressed i in the middle. Thorax rather 
strongly transverse, slightly narrower than the elytra, 


co) 
nearly straight at the sides, with the base rounded, yellowish 
in colour, very finely punctured and obscurely ‘impressed 
along the middle. Elytra a little longer than the thorax, 
finely and closely, but distinctly, punctured. Hind body 
yellow, with the 5th and 6th segments infuscate, very 
finely and not densely punctured, the apical segments 
rather more sparingly so than the basal ones. Legs pale 


yellow. 


Staphylinide of the Amazon Valley. 65 


In the male the hind margin of the dorsal plate of the 
7th segment of the hind body is emarginate in the middle, 
and on each side of the middle, so as to form four almost 
equidistant teeth; the middle ones are short prominences, 
the lateral ones are quite as elongate as the middle ones 
and more slender and more spine-like. 

Rio Purus; a single male found by Dr. Trail (after 
whom I have named the species), on the 13th Oct. 1874. 

Obs.—This species in the structure of its tarsi and 
sternal processes much resembles H. gilva; it is rather 
larger than that species, has the surface less opaque because 
less densely punctured; the antenne differently coloured, 
with the 4th joint larger, and the male characters different. 
From H. brevis, the less densely punctured upper surface, 
and the different structure of the intermediate joints of the 
antenne, readily distinguish it. It is probable that the 
individual described is a little immature. 


6. Homalota culpa, n. sp. Rufo-testacea, antennis apicem 
versus pallidioribus ; capite, elytrorum medio, abdomineque 
ante apicem, infuscatis; capite, thorace, elytrisque sub- 
tiliter punctatis, abdomine impunctato; prothorace trans- 
versim subquadrato. Long. corp. 1 lin. 


Antenne stout, moderately long, a good deal thickened 
towards the extremity, the basal portion yellowish, the 
apical very pale yellow; 2nd and 3rd joints elongate, about 
equal to one another ; of 4—10 each is distinctly broader, 
but scarcely shorter than its predecessor, the 4th longer 
than broad, the 10th rather strongly transverse; the 11th 
joint rather stout, as long as the two preceding together. 
Head broad and short, without distinct neck, a good deal 
narrower than the thorax, finely punctured, infuscate. 
Thorax about as broad as the elytra, a good deal broader 
than long, the sides a little rounded in front, distinctly 
narrowed behind the middle, the hind angles distinct but 
very obtuse, the sides and base with a very fine but dis- 
tinct margin; the colour is yellowish, the surface very 
finely punctured without channel or fovea. LElytra broad 
and short, a little longer than the thorax; their hind 
margin not (or scarcely) sinuate at the outer angles, their 
colour yellowish, but with a very broad, ill-defined, smoky- 
violet colour across the middle, their punctuation fine and 
rather dense. Hind body broad, a little rounded at the 


TRANS. ENT. sOC. 1876.—PART I. (MAY.) F 


66 Mr. D. Shar Contributions to the 


sides and narrowed behind, yellowish in colour, with the 
6th segment infuscate, shining and without punctuation ; 
beneath finely and closely punctured and pubescent. Legs 
pale yellow. ‘Tibixe slender and elongate. 

Tapajos; two specimens. Perhaps found in company 
with Oxypoda aliena, which the species much resembles, 
though it is a good deal larger. 

Obs.—In this species the gene are immarginate; the 
middle cox are widely separated; the apex of the meta- 
sternum is truncate and separated from the little produced 
portion of the mesosternum by a narrow black space. The 
anterior tarsi are 4-, the intermediate and_ posterior 
5-jointed; the basal joint of the middle tarsus is about 
equal in length to the 2nd joint; the basal joint of the 
hind tarsus is elongate and about equal in length to the 
two following joints together. 


TACHYUSA. 


About thirty species, most of them European, are at 
present included under this generic name; none of them 
are from tropical America, but two are described by 
Fauvel, from Chili. The genus has not yet been treated 
of by Rey, but we may confidently expect that in the 
forthcoming part of his work the name T'achyusa will be 
used with a very different application to that of the works 
of Erichson and Kraatz. 

As regards the two species here described I need only 
remark that they appear closely allied inter se, and that 
they are not nearly allied to any of our European species. 


1. Tachyusa picticornis, n.sp. Testacea, nitidula, fere 
impunctata, antennis articulis 3—6 rufescentibus, 7—11 
albidis. Long. corp. 12 lin. 

Broader than 7. ferialis. Antenne long, reaching 
about to the end of the elytra, rather stout for this genus, 
a little thickened towards the extremity; joints 1 and 2 
yellowish; 3rd joint one and a half times the length 
of the 2nd; 4th about as long as the 2nd, but stouter ; 
5—10 each just a little shorter and stouter than the pre- 
ceding, 5th much longer than broad, 10th about as long 
as broad; last joint long and pointed, two and a half times 
the length of the tenth; joints 3—6 brownish, those be- 
yond abruptly paler, almost white. Head about as broad 
as the thorax, yellowish; the eyes black, large and pro- 


Staphylinide of the Amazon Valley. 67 


minent. Thorax about as long as broad, dilated in front, 
with the anterior angles rounded; again just a little 
broader at the posterior angles, which are deflexed and 
obtuse ; yellowish, shining and impunctate. Elytra much 
broader and a little longer than the thorax, also a 
little darker in colour. Hind body smooth, shining and 
impunctate, its sides gently rounded, scarcely any nar- 
rower at the base than at the 6th segment. Legs yellow, 
elongate and slender; posterior tarsi with the three basal 
joints elongate, each a little shorter than the preceding 
one; middle coxz widely separated, mesosternum very 
little produced between them, and separated from the pro- 
duced point of the metasternum by a broad space. 
Tapajos; one individual. 


2. Tachyusa extranea, nu. sp. Rufo-testacea, capite, 
elytris abdominisque segmento sexto obscurioribus ; sub- 
tilissime punctulata, thorace subquadrato, obsolete canali- 
culato, elytris hujus longitudinis. Long. corp. 14 tin. 


This species has much the form of a Homalota. The 
antenne are yellowish, elongate and rather stout, slightly 
thickened towards the apex ; 3rd joint a little longer than 
the 2nd; 4th shorter than the 2nd; 5—10 differing but 
little in length, 10th about as long as broad; 11th joint 
long, rather pointed, more than twice as long as the 10th. 
Head brownish-yellow, slightly narrower than the thorax, 
short, smooth, shining and impunctate. Thorax yellowish, 
with the sides in front dilated, rounded and much de- 
flexed; it is about as long as broad, indistinetly chan- 
nelled, almost imperceptibly punctured. ‘The elytra are 
broader than the thorax, about as long, a little darker in 
colour, and with their punctuation not quite so obsolete. 
The hind body is but little narrowed at the base; it is 
yellowish, with the 6th segment a little darker; it is 
smooth, shining and impunctate. The legs are yellowish ; 
the posterior tarsi slender and moderately long. 

Tapajos; two individuals, much mutilated. 

Obs.—This species appears to be nearly allied to 
T. picticornis, at any rate in so far as the structure of 
the sternum is concerned; its tarsi I have been unable 
to examine. Its smaller size and unicolorous antenne 
render it easily distinguishable from 7. pzeticornis.

68 Mr. D. Shar Contributions to the 


OXYPODA. 


Only one species with this generic name is as yet 
described from tropical America; a number of species 
have, however, been described from Chili by M. Fauvel. 
The single species I here describe differs a good deal 
in its form from our European species of the genus, 
and resembles rather the Chilian O. scutellata. I have 
also one or two other closely allied Brazilian species in 
my collection, so that probably these South American 
species will be distinguished ultimately as a separate 
genus. 


1. Oxypoda aliena, n. sp. Latior, omnium subtilissime 
punctulata, prothorace valde transverso, elytris latiore ; 
abdomine apicem versus attenuato, evidentius pubescente ; 
testacea, elytris abdomineque ante apicem fusco-signatis. 
Long. corp. 1 lin. 


This species is remarkable for its short and very broad 
form, its prothorax being particularly broad and short. 
Antenne yellow, rather long, distinctly thicker towards 
the apex; joints 2 and 3 about of equal length; 4th joint 
much shorter than the 3rd; from the 4th to the 10th the 
joints differ but little in length, each is just a little broader 
than its predecessor, 4th joint slender, much longer than 
broad, 10th about as long as broad; last joint long, quite 
twice as long as the 10th, rather pointed. Head broad, 
nearly half as wide as the thorax, yellow, shining, and 
with the finest possible punctuation and pubescence. 
Thorax three times as broad as long, the sides very gently 
rounded, just a little narrower at the front than at the 
hind angles; all the angles, especially the front ones, ex- 
tremely rounded, without channel or fovea, yellow, and 
with an almost invisible punctuation and pubescence. 
Elytra distinctly narrower than the thorax, but about as 
long, yellow, slightly obliquely darker across the middle 
with the external angle a little paler, with an extremely 
fine punctuation and pubescence. Hind body much 
narrowed at the apex, extremely finely and closely punc- 
tured, with a depressed, long and distinct, though ex- 
tremely fine pubescence ; the 5th segment a little darker 
in colour than the others. Legs yellow; hind tarsi with 
the joints elongate and slender, the 1st more than twice as 
long as the second. 

Tapajos; four individuals. 


Staphylinide of the Amazon Valley. 69 


ALEOCHARA. 


The four species described under this generic name 
appear to be closely allied in structure to one another and 
to the European A. fuscipes. Allied species appear to 
be found all over the world, and some species have an 
extremely wide geographical range. I have, however, 
seen no specimens of any of the species here described 
from any other locality than the Amazons, and I have 
also failed to identify any of the four with species pre- 
viously described from tropical America; in which part 
of the world, I may remark, that allied species are no 
doubt pretty numerous, though as yet scarcely a dozen 
have been described as purporting to belong to the genus 
and to the locality mentioned. 


1. Aleochara prisca, n. sp. Latior, nigra, antennis 
medio subincrassatis, elytris fuscis, thorace brevioribus ; 
pedibus fusco-testaceis, ano rufo-testaceo, abdomine sat 
crebre minus fortiter punctato. Long. corp. 4 lin. 


Allied to A. fuscipes. Antenne black, very stout, 
with the joints very short ; 2nd and 3rd joints slender, the 
latter the longer; 4th strongly transverse ; 5—7 similar 
to one another, 5th considerably broader than the 4th, 
after the 7th slightly narrower again to the extremity. 
Head very much narrower than the thorax, distinctly but 
not closely punctured. Thorax rather narrowed in front, 
its breadth about one and a half times its length, mode- 
rately closely and distinctly punctured. Elytra_consider- 
ably shorter than the thorax, not quite black, closely and 
distinctly punctured. The hind body is broad, not nar- 
rowed till the 6th segment, moderately closely and strongly 
punctured; the punctuation of the basal segments finer 
than that of the rest; the 7th segment, as well as the 
hind margin of the 6th, reddish. Legs pitchy, with the 
anterior tibiz yellowish. 

Ega; one specimen, which appears to be a female. 

Obs.—This species appears to be very closely allied to 
the European A. fuscipes, but it has the elytra darker 
and the extremity of the hind body paler; the 4th joint 
of the antennz is more transverse; the head has an im- 
punctate space on the disc, and the punctuation of the 
hind body is rather finer and closer. 


2, Aleochara verecunda, n. sp. Nigra, antennis basi, 


al 


70 Mr. D. Sharp’s Contributions to the 


pedibusque testaceis, elytris thorace brevioribus anoque 
obscure rufis; thorace crebre minus subtiliter punctato ; 
abdomine apicem versus subattenuato. Long. corp. 3} lin. 


Allied to A. fuscipes, and almost equal in size thereto, 
but rather more slender, and with the red of the extremity 
of the hind body more distinct. The antennz are short 
and stout, the three first joints yellow; the 3rd a little 
longer than the 2nd; the 4th strongly transverse, but 
much narrower than the 5th; the rest strongly transverse, 
slightly narrower after the 7th to the extremity ; last joint 
quite twice as long as the preceding one. Palpi obscurely 
yellowish. Head narrow, scarcely half so wide as the 
thorax, rather coarsely but not closely punctured. Thorax 
narrowed to the front, its breadth quite one and a half 
times its length, closely and strongly punctured. Llytra 
considerably shorter than the thorax, reddish, closely and 
rather strongly punctured. Hind body slightly narrowed 
to the extremity ; 2nd and 3rd segments sparingly and 
finely punctured, the rest coarsely but not closely ; the 
7th segment and the hind portion of the 6th reddish. 
Legs dull yellowish. 

Tapajos ; one specimen, which is, I have no doubt, a 
female. 

Obs.—Though closely allied to A. prisca, this species 
may be readily distinguished from it by the pale basal 
joints of the antenneze. 


3. Aleochara auricoma, n. sp. Rufo-testacea, fulvo- 
pubescens, capite nigro, antennis abdominisque segmentis 
2—5 nigricantibus; elytris thorace brevioribus ; abdomine 
seomentis 3—7 sat crebre punctatis. Long. corp. 4 lin. 


Antenne blackish, with the apical joint blackish-yellow, 
stout; 3rd joimt one and a half times the length of the 
2nd; 4th scarcely so long as broad; 5—10 strongly 
transverse ; last joint elongate, rounded at the extremity, 
more than twice as long as the tenth. The head is black, 
rather strongly but not closely punctured. ‘The thorax is 
yellow, ample, its breadth one and a third times its length ; 
its base and hind angles much rounded, narrower im front 
than behind ; it is moderately, finely and closely punec- 
tured, without channel or fovea. The elytra are not more 
than two-thirds the length of the thorax, with a similar 
colour and punctuation to it. The hind body is pitchy- 
red at the extreme base, the segments becoming darker 


Staphylinide of the Amazon Valley. ri 


till the 5th, which is quite black; the 6th and 7th bright- 
orange; segment 2 almost impunctate ; the 3rd _ rather 
sparingly and moderately finely, the 4th—7th evenly and 
distinctly, but not densely, punctured. Legs yellow. 

Ega; two specimens, one of which I have ascertained 
by dissection to be a male, while the other I suppose to be 
a female. The male carries no external indication of its 
sex ; the dorsal and ventral plates of the 7 th segment are 
both truncate, with the angles rounded, and without visible 
crenulations. 


4. Aleochara mundana, n. sp. Ferruginea, capite abdo- 
mineque (apice excepto) nigricantibus ; crebre sat fortiter 
punctata; elytris thorace brevioribus. Long. corp. 23— 
23 lin. 

Similar in build to A. éristis, but rather larger, very 
differently coloured. Antenne tawny, the 3rd joint a little 
longer than the second, 4th short and transverse, 5th con- 
siderably broader than the 4th ; after this the joints become 
no broader, each markedly transverse; the last joint twice 
as long as the preceding. Palpi tawny. Head black, 
half the width of the thorax, moderately distinctly punc- 
tured, with a well-marked yellow pubescence. Thorax 
tawny, nearly twice as broad as long, a little narrowed in 
front, rather closely and finely punctured, with a yellow 
pubescence. Elytra tawny, very short, considerably shorter 
than the thorax, rather closely and finely punctured. Hind 
body tawny black at the base, darker till the 5th segment, 
which is quite black; the 6th segment (except the base) 
and the 7th orange-coloured; rather closely punctured, 
the basal segments more finely than the apical ones; 
scarcely narrowed till the 6th segment. The legs are 
yellow. 

This is probably a very common species in the Amazon 
district, extending from Para to Ega. I have five speci- 
mens before me, coming from Para, Tapajos and Ega; 
one of them bears a ticket,—“ in dung.” 

Obs.—This species, though very closely allied to A. au- 
ricoma, is easily distinguished therefrom ; it is a little 
smaller, and its colours are not quite so brightly con- 
trasted; the antenne are paler and less stout than in 
A. auricoma, and the punctuation of the upper surface is 
a little fer and closer. There are no external marks of 
the sexes to be seen. 


72 Mr. D. Sharp’s Contributions to the 


GYROPHAENA. 


Eleven species referred by me to this genus are here 
described: one of these, viz., G. pumila, is among the 
smallest of known Staphylinide ; two others, G. boops 
and G. debilis, depart widely from the European species 
of the genus, inasmuch as they have the eyes of unusual 
size, far surpassing in this particular any other Aleocha- 
ride known to me. LErichson has already described, from 
Brazil and North America, one or two species resembling 
them in this respect, and the European species differ 
somewhat from one another in the size of the eyes and the 
form of the head, so that I do not consider that it is at 
present advisable to make a distinct generic name for these 
insects. 

The genus, as at present understood, is probably distri- 
buted over nearly all quarters of the world, but the extra- 
European species as yet described are not very numerous ; 
only three, in fact, have yet been described from tropical 
America; though, judging from the number here de- 
scribed, as well as from numerous other species in my 
collection, it is pretty certain that these insects will prove 
to be very rich in species in South America. 


1. Gyrophena pumila, n.sp. Fusca, nitidula, fere im- 
punctata, antennis pedibusque testaceis, prothorace valde 
transverso, basi et lateribus rotundatis. Long. corp. 
3 hn. 

Antenne short and stout, yellow; 2nd joint stout; 
3rd joint small, much shorter and thinner than 2nd, the 
basal much narrower than the apical portion; 4th joint 
much smaller than the following ones; 5—10 nearly equal 
to one another in breadth, the 10th, however, a little 
broader and longer than the 5th, each of them transverse ; 
11th joint stout, obtuse. Head small, a good deal nar- 
rower than the thorax ; the eyes small, the surface smooth 
and shining. ‘Thorax very transverse, a little narrower 
than the elytra, more than twice as broad as long; the 
base greatly rounded, the surface smooth and_ shining. 
Elytra short, a little longer than the thorax, with a few 
indistinct and distant punctures. Hind body impunctate. 
Legs yellow. 

Rio Purus, 24th September, 1874, Dr. Trail ; a consi- 
derable number of examples were found, but most of them

have come to pieces in the spirit in which they were pre- 
served. 

Obs.—This minute insect is smaller than the European 
G. boleti, and in size scarcely equals our smallest Oligote. 
I find it not easy to see with distinctness the form of the 
hind margin of 7th segment, but I believe the dorsal plate 
has the hind margin a little obtusely prominent in the 
middle, and has a curved spine on each side. 


2. Gyrophena parvula, ni. sp. Nigro-fusca, nitidula, 
fere levis, elytris parce punctatis, antennis pedibusque 
testaceis; prothorace valde transverso, basi et lateribus 


: aie 
rotundatis. Long. corp. 3 lin. 


This species is extremely similar to G. pumila, but the 
elytra are more distinctly, and not quite so sparingly 
strewed with punctures, which on examination with a high 
power appear to me to be fine elevated granules; besides 
this, it is larger and broader, with the head especially a 
good deal broader 5 in other respects it appears extremely 
similar to G. pumila. 

A single individual, found on the Rio Purus with 
G. pumila by Dr. Trail. 


3. Gyrophena parca, NU. Sp. Nigro-fusca, nitida, an- 
tennis fuscis, basi pedibusque testaceis; parcissime punc- 
tata, prothorace valde transverso, disco subtiliter quadri- 
punctato. Long. corp. Z lin. 


Antenne short and stout ; the four basal joints yellow, 
the others infuscate; 3rd joint much smaller than 2nd, its 
basal portion constricted ; 4th joint extremely small; 5— 
10 similar to one another, each rather strongly transverse ; 
11th short and obtuse. Head broad, but a good deal 
narrower than thorax, shining, black, with a few very 
fine punctures; the eyes moderately large. Thorax 
strongly transverse, much rounded at the base, and dis- 
tinctly narrowed towards the front; pitchy, very shining, 
with four fine punctures on the middle, placed so as to 
form the corners of a square. Elytra short, but a good 
deal longer than the thorax, pitchy, shining, with a very 
few indistinct punctures. Hind body pitchy, slightly paler 
at the base and extremity; almost impunctate, but not 
quite so shining as the anterior parts. Legs yellow. 

In the male the hind margin of the dorsal plate of the 
7th segment of the hind body is produced in the middle so

as to form two short, stout, almost confluent teeth, and it 
has also at each outer angle a rather longer and more 
slender pointed spine.

November, 1874; a single male from each locality, cap- 
tured by Dr. Trail.

nigro-picea, antennarum basi pedibusque testaceis; pro- 
thorace disco quadripunctato; elytris parce punctatis. 
Long. corp. 1 lin. 

In the male the hind margin of dorsal plate of the 7th 
segment of the hind body is armed in the middle with two 
fine, pointed, approximate spines, and on each side with a 
stouter, distinctly incurved spine ; the hind margin is most 
prominent in the middle, so that though the outer spines 
are considerably longer than the two middle ones they do 
not project farther backwards. 

Garrao, 11th November, 1874; two male individuals 
found in fungus by Dr. Trail. 

Obs.—This species is excessively closely allied to G. 
parca, and agrees almost exactly with it in most respects ; 
but it is a little larger and more convex, and is readily 
distinguished by the different character of the teeth on the 
7th segment of the hind body in the male. 


5. Gyrophena juncta, n. sp. Picea, nitidula, anten- 
narum basi pedibusque testaceis; elytris abdomineque

Obs.—The male characters here scarcely differ from 
G. levis, but in other respects the two species are easily 
distinguished ; the coarse punctures on the elytra of the 
G. juncta will afford an easy means of distinguishing the 
species from G. levis.

a few obsolete tubercles; the dorsal plate of the 7th seg- 
ment is transversely depressed along the middle, and 
beyond the depression is produced as a large triangular

large and convex, occupying the whole side of the 
head, coarsely facetted ; the space between them is quite 
parallel-sided, shining, and almost impunctate. Thorax 
very strongly transverse, more than twice as broad as 
long, slightly narrowed behind, the base rounded; it is 
of a shining-yellowish colour, and is almost impunctate. 
Elytra a good deal longer than the thorax, shining, black-

setigerous punctures. Hind body yellow, with the penul- 
timate segments blackish, the segments very finely and 
sparingly punctured, and also sparingly pubescent. Legs 
clear yellow. 

In the male the elytra bear each near their hind margin 
two tubercles, one near each angle; the dorsal plate of 
the 6th segment of the hind body bears in the middle, at 
the base, an oblong, large, shallow impression; the hind 
margin of the following segment exhibits an obtuse, 
tubercle-like projection in the middle, and on each side 
a very short spine.

above described is one of the largest and most developed 
males; the thorax is sometimes infuscate, and even quite 
pitchy, and the dark colour in other cases reduces the pale 
colours to smaller areas. The tubercles on the elytra of 
the male seem in some cases nearly to disappear, and pos- 
sibly in some individuals of that sex may be quite absent.

The male of this species has a minute tubercle at the 
hinder and inner angle of each elytron; the dorsal plate 
of the 6th segment of the hind body has an indistinct 
impression on the middle of the basal portion; the hind 
margin of the following plate is narrow, and very nearly 
truncate; the middle being scarcely visibly prominent, 
and the outer angle on each side bearing only a very short, 
indistinct, obtuse projection. 

Rio Purus, 13th October, 1874; a single male found 
by Dr. Trail, and a second individual found at Garrao, in 
fungus, on the 11th November, 1874. 

Obs.—I am by no means sure that this individual may 
not ultimately be shown to be an extremely undeveloped 
male of the variable G. doops. It is, however, rather 
smaller than the smallest individual of that species, and 
the colours are paler than the palest thereof; the 4th joint 
of the antennz appears to be smaller in proportion to the 
5th, and the male peculiarities of the hind margin of the 
7th segment are so reduced as to be almost absent. Should 
this insect ultimately be shown by a series of intermediate 
individuals to be a mere form of the G. boops, we shall 
then have demonstrated to us that the male secondary 
sexual characteristic in this species (as is known to be the 
case with many larger Coleoptera of different families) 
' may be in some individuals almost entirely absent ; and 
this will be all the more interesting, as in this case we shall 
see that this diminution of the male peculiarities extends 
even to those external parts that are in most immediate 
proximity to the primary sexual organs; for I have con- 
vinced myself, by numerous dissections of Gyrophene, 
that the edeagus and its coverings have their chief attach- 
ore to the dorsal plate of the 7th segment of the hind 

ody.

80 Mr. D. Sharp’s Contributions to the 


DEINOPSIS. 


Only five species of this extremely distinct and peculiar 
genus have yet been described, but they come from very 
different parts of the world, so that this genus is probably 
nearly universally distributed. No species has hitherto 
been made known from South America; but I have, be- 
sides the two species here described, one or two others from 
that quarter, so that it would seem probable the species 
will prove to be rather more numerous there than else- 
where. 


1. Deinopsis Matthewsi, nu. sp. Opacus, nigro-fuscus, 
dense subtilissime punctatus. Antennis, palpis pedibusque 
rufescentibus, antennis medio infuscatis. Long. corp. 
24 lin. 

Very similar in form to D. fuscatus, but larger, and 
with the antennze more slender and elongate; they are 
rather less than { lin. in length; 3rd joint a little shorter 
than 2nd, but a little longer than 4th; 5—9 very similar 
to one another in length; 10th a little shorter than 9th; 
11th jomt shorter than 10th, and terminated by a seta- 
like spine. The palpi and front of the head are obscure 
red. The margins of the thorax are also very obscurely 
red. The elytra are very deeply sinuate at their outer 
angle. 

A single individual of this species was found by Mr. 
Bates, but I have no exact indication of its locality; the 
specimen is, I believe, a female. 

I have named this species in honour of the Rey. A. Mat- 
thews, who has displayed a most extraordinary amount 
of entomological skill in his treatment of the Trichopte- 
rygide, and to whom this genus is of special interest, 
as he considers it to make a remarkable approach in many 
points, both of internal and external structure, to the 
Trichopterygide. 


2. Deinopsis longicornis, n. sp. Ferrugineo-nigra, 
antennis, palpis pedibusque rufis; antennis tenuissimis, 
valde elongatis. Long. corp. (abdomine extenso) 3 lin, 

Very similar in form to D. fuscatus, but much larger, 
and of a more rusty black colour. The antenne are yel- 
lowish-red, very slender and elongate, being just over one 
line in length. The front of the head, the margins of the 
thorax, and the extremity of the hind body, are of an 


Staphylinide of the Amazon Valley. 81 


obscure rusty colour. The sinuation at the extremity of 
the elytra is extremely deep. 

Tapajos; a single female individual. 

Obs.—Though very closely allied to the D. Matthews, 
I believe the elongate antennz indicate this to be a dis- 
tinct species; it is also a little larger, its head being 
notably broader. 


CoPpROPORUS. 


Under this generic name I have described sixteen new 
species; all these would, in Erichson’s classification, find 
their position in T'achinus, Family I. Kraatz and others 
have proposed more than one other generic name for 
insects that would by Erichson have been located as 
above mentioned; but these names I have not adopted, 
because I feel extremely doubtful as to what amount of 
generic differentiation will be found to exist among these 
insects; for it is evident that a vast number of closely- 
allied species exist in the warmer parts of the world, and 
that only an insignificant fraction of their number are as 
yet known to us; and I consider it is therefore premature 
to attempt to predict where the limits of aggregation of 
the species will ultimately be found. It is sufficient for 
my present purposes to state that all the Tachyporini 
here described as Coproporus are comparatively little 
elongate in form, have the anterior half of the body very 
shining and glabrous, the mesosternum carinate, and the 
front tarsi in the male scarcely dilated (this latter character 
being of course only inferred in the case of those species 
of which the female alone is known to me). Tachyporini 
possessing these characters appear to be very numerous in 
species in the warm parts of the world, and South America 
appears to be specially rich in them, so that their study 
will not be without difficulty, leaving out of consideration 
generic questions. In all the cases in which I have ob- 
served the edeagus, it is but small, without appendages, 
and differs but slightly from species to species; on the other 
hand, the external sexual characters of the apical segments 
of the hind body offer remarkable and striking distinctions, 
so that their examination much facilitates the recognition 
of the species.

Very convex; of a pitchy colour. Antennz with the three 
basal joints yellow, the rest infuscated; they are rather 
long and slender, a little incrassated towards the extremity; 
3rd joint scarcely so long as the 2nd; 4th considerably 
shorter than the 3rd; 4—10 differing but little in length, 
but the apical ones evidently stouter than the others; 11th 
joint rather stout, longer than the 10th, its extremity 
paler. Head pitchy-black, the parts of the mouth and 
palpi yellowish. Thorax pitchy in colour, a little paler at 
the sides, very much narrowed to the front; the base dis- 
tinctly sinuate on each side, and the posterior angles 
projecting backwards, their extremity rounded. Elytra 
longer than the thorax, but about as broad, their sides 
gently curved, evidently narrowed to their outer hind 
angle, which is broadly rounded, very finely and sparingly 
punctured. Hind body, when extended, very much 
narrowed to the extremity, pitchy in colour, its punctua- 
tion more distinct than that of the elytra. Legs yellowish. 

In the male the dorsal plate of the 7th segment of the 
hind body ends in four spines, of which the two middle 
ones are closer to one another than to those at the sides, 
and are more slender and project farther backwards; the 
lateral notch on each side extends a good deal farther 
forwards than does the middle one; the ventral plate of 
the same segment bears at the extremity a deep and ex- 
tremely broad triangular excision.

In the female the dorsal plate of the 7th segment of

distant spines, the two in the middle being distinctly 
more slender, but scarcely longer than the lateral; the 
ventral plate also ends in four spines, of which the two 
in the middle are rather stouter than the lateral, and 


Staphylinide of the Amazon Valley. 83 


the interval between them is distinctly less than that 
between the middle and lateral ones. 

Ega; a single female. 

Obs. I—This species so closely resembles C. rotun- 
datus, that I at first supposed them to be the sexes of a 
single species; careful observation reveals, however, such 
important differences, that I have no doubt these are 
specific. C. similis is a little smaller; it has the antennee 
considerably shorter, the eyes smaller and less prominent, 
the hinder angle of the elytra much less rounded, and the 
tarsi a good deal shorter. 

Obs. IT.—Besides the female individual above described 
and named, I have a male specimen from the same locality, 
which is slightly larger, and has the sides of the elytra a 
little more rounded, so that I am not quite sure whether 
it belongs to this species or not. I give, however, a 
description of its sexual characters as follows. 

In the male the dorsal plate of the 7th segment of the 
hind body ends in four almost equidistant spines, the 
middle ones being much more elongate than the lateral ones; 
the three spaces between the spines extend about equally 
far towards the front; the ventral plate has at the extre- 
mity a broad notch, the sides of which are sinuate, and its 
hinder angles somewhat produced, in the form of short 
teeth. 


3. Coproporus obesus, n. sp. Latior, convexus, piceo- 
niger, nitidus, antennis tenuioribus pedibusque testaceis ; 
capite prothoraceque lvissimis, elytris parce subtilissime 
punctatis, angulo externo rotundato, intra marginem late- 
ralem obsolete impresso. Long. corp. 24 lin. (abdomine 
extenso). 


Very closely allied to C. rotundatus ; a little broader and 
darker, the antennze more slender at the extremity, and 
the sides of the elytra just a little turned outwards, so as 
to give them the appearance of being indistinctly impressed 
along the margin. Antenne long and slender, slightly 
stouter at the extremity, yellowish, 2nd and 3rd joints 
differing little in length; after this the joints to the 10th 
differ but little in length, the 10th being stouter and a little 
shorter than the 4th; it is evidently longer than broad ; 
11th joint rather long. The head is blackish, smooth and 
shining, the parts of the mouth and the palpi yellowish. 
The thorax is very much narrowed to the front ; it is pitchy

black, paler at the sides; it is broadly but slightly sinuate 
at the base on each side, the extreme hind angle just a 
little rounded. The elytra are the width of the thorax at 
the base, almost straight at the side, a little narrowed 
behind, the hind angle much rounded; they are sparingly 
and extremely finely punctured. The hind body is pitchy, 
with the last segment and the hind margins of those before 
it paler; its punctuation fine, closer and more distinct 
than that of the elytra. The legs dark yellowish. 

In the female the dorsal plate of the 7th segment of the 
hind body terminates in four very long, equidistant, slender 
spines, of which the two middle ones are slightly more 
slender than the lateral ones ; the ventral plate of the same 
segment also ends in four slender spines, of which the two 
in the middle are rather longer, but not stouter than the 
lateral ones. 

Ega; two female specimens. 


4. Coproporus retrusus, n. sp.  Piceus, conyexus, 
nitidus, antennis apicem versus incrassatis, pedibusque 
rufis; capite prothoraceque leevissimis, elytris parce sub- 
tilissime punctulatis, lateribus subparallelis, angulo externo 
minus fortiter rotundato. Long. corp. 2} lin. 


This species is very closely allied to the three preceding 
ones, and is about the same size, but has the antennz 
stouter and more thickened towards the extremity, and 
its elytra are straighter at the sides. Antennze moderately 
long, rather stout, distinctly thickened towards the ex- 
tremity, of an obscure reddish colour in the middle, with 
the three basal and the 11th joints paler ; 3rd joint longer 
than the 2nd; 4th to 10th each a little shorter and 
broader than its predecessor, the 10th scarcely so long as 
it is broad; 11th joint stout, one and a half times as 
long as the 10th. Thorax as broad as the elytra, much 
narrowed to the front; a little sinuate at the base on each 
side, so that the hinder angles project a little backwards, 
the extremity of these rounded. Elytra rather straight 
at the sides, with the external angle moderately rounded, 
without any lateral impression ; very finely and sparingly 
punctured. Legs dark yellowish. 

In the female the ventral plate of the 7th segment of 
the hind body ends in four spines, of which the two 
middle ones are very elongate; the lateral ones are a good 
deal shorter than the middle ones, and but little stouter ; 


Staphylinide of the Amazon Valley. 85 


besides these the outer angle on each side is also 
produced, and forms a distinct short spine, so that 
the ventral plate is really six-spined, the outside tooth 
being only half the length of the one next it. The dorsal 
plate is four-spined, but, as the spines are broken in the 
individual described, I cannot speak of their relative 
lengths.

Antennz rather short and stout, the three basal joints 
yellow; 4—10 pitchy, 11th yellowish; 2nd and 3rd 
joints subequal in length; joints 4—10 differing but 
slightly from one another in length, each a little broader 
than its predecessor, the 4th rather longer than broad, 
the 10th not quite so long as broad; 11th obtusely 
pointed, much longer than 10th. Head blackish, im- 
punctate, the palpi yellow. Thorax pitchy, with the sides 
paler, shining and impunctate, the base but little sinuate, 
so that the rounded hind angles are very little produced 
backwardly. Scutellum impunctate. Elytra rather broad 
and short, a good deal longer than the thorax, only a little 
curved at the sides, and with the hind angle only mode- 
rately rounded; they are very finely’ but yet distinctly 
punctured, and have a broad obsolete impression near the 
lateral margin. Hind body broad and short, pitchy, paler 
towards the extremity, rather closely and distinctly punc- 
tured, but little shining. Legs red. 

In the female the dorsal plate of the 7th segment of 
the hind body ends in four long equidistant spines, of 
which the middle ones are a little the longer; the three 
notches between the spines extend about equally far 
forwards. The ventral plate ends in four long spines 
and two short lateral teeth; the two middle teeth project 
shghtly farther back than those next them, and the notch 
separating them is narrower and does not extend quite 
so far forwards as the notch next them.

Anana, 6th September, 1874; a single female, brought 
back by Dr. Trail. 


7. Coproporus brevis, n. sp. Convexus, pernitidus, 
niger, abdomine piceo, antennis rufo-testaceis, pedibus 
rufis; prothorace basi fere truncato; elytris crebre punctu- 
latis, lateribus sat rotundatis. Long. corp. 1? lin. 


Antenne yellowish, only moderately long, rather stout, 
distinctly thickened towards the apex; joints 2 and 3 
differing but little in length ; 4—10 differing little from 
one another in length, the 10th not quite so long as 
broad; 11th joint stout, a little paler than the others. 
Head black, shining, impunctate. Thorax as broad as 
the elytra, narrowed towards the front; the hinder angles

rounded; the base scarcely sinuate, smooth, shining and 
impunctate ; the lateral margins pitchy. The elytra are 
nearly black, longer than the thorax, very finely punc- 
tured, without impression near the side; the hind angle 
a good deal rounded. 

In the male the dorsal plate of the 7th segment ends in 
four almost equidistant spines, of which those in the middle 
are the more slender, and a good deal the longer; the 
ventral plate bears a deep angular notch, the sides of 
which are a good deal produced, so as to form projecting 
teeth. 

Bga ; two male specimens. 

Obs.—This species appears to be extremely closely 
allied to C. politus, and has the mesothoracic carina 
similar, but the antenne are entirely pale; I am sorry 
I am unable to compare the sexes of the two species. 


8. Coproporus ignavus, Ni. Sp. Sat convexus, nitidus, 
piceus, antennis basi rufo, articulo ultimo apice testaceo, 
pedibus rufis; prothorace basi utrinque leviter sinuato ; 
elytrorum angulo externo sat rotundato. Long. corp. 
2 lin. 


Antenne moderately long, rather slender, but a good 
deal thickened towards the extremity; the three basal 
joints yellow, the following ones pitchy, the extremity of 
the 11th yellow; 3rd joint fully as long as 2nd; 4th joint 
longer than broad ; 10th very nearly as long as broad. 
Thorax very transverse, the hind angles a little rounded 
put not produced, the base a little sinuate on each side ; 
it is of a pitchy colour, with the sides paler, almost im- 
punctate. Elytra very finely and not closely punctured, not 
impressed at the sides, the hind angle moderately rounded. 
Hind body pitchy, paler towards the extremity, rather 
closely and distinctly punctured. Legs red. 

In the female the dorsal plate of the 7th segment ends 
in four elongate spines; the middle ones are the more 
slender, they are a little longer than the lateral ones, and 
the space between them is not quite so broad as that 
between them and the side spine ; the three spaces extend 
about equally far forward ; the ventral plate ends in four 
spines about equally stout; those in the middle are distinctly 
longer than the side ones, and the space between them is 
scarcely so broad as that between them and the lateral 
spine; the middle space does not extend so far forward as 


88 Mr. D. Sha Me Céairibaitone to the 


the lateral space; the outside of this plate is also a little 
produced, so as to form a short tooth. 

Anana; a single female found on the 6th September, 
1874, by Dr. Trail. 

Obs.—This species appears to be almost intermediate 
between C. similis and C. politus ; the less-produced hind 
angles of the thorax readily distinguish it from the former, 
while from the latter it is separated by the more rounded 
angles of the elytra and the sexual differences of the apical 
segment in the female. The mesothoracic carina has 
been smashed by an accident in the individual described. 


9. Coproporus inclusus, n. sp. Convexus, nitidus, 
iceus, antennis pedibusque testaceis; capite thoraceque 
p q 3 
leevigatis ; elytris obsolete punctatis, angulo externo 
obtuso; thorace basi subtruncato. Long. corp. 1} lin. 


Antenne yellowish, slender, rather short, a little 
thickened towards the apex; joints 1, 2, 3, differing but 
little from one another in length, 3rd the most slender ; 
4th much shorter than 3rd, a little longer than the 5th; 
5—10 differmg but little in length, each just a little 
shorter and a little broader than its predecessor, 10th 
scarcely so long as broad; 11th a little stouter than the 
10th, and twice as long. Thorax ample, of a pitchy 
colour, very shining, transversely very convex, much nar- 
rowed towards the front; hinder angles rounded; the base 
slightly sinuate on each side near the outer angle. Elytra 
pitchy red, about one-third longer than the greatest length 
of the thorax; they are very finely and indistinctly punc- 
tured, and the outer angle is not greatly rounded. Hind 
body reddish. Legs yellow. Mesothoracic carina not 
much developed. 

In the female the dorsal plate of the 7th sezment ends 
in four spines, of which the middle ones are more slender 
and a little longer than the outer ones; the middle space is 
but little narrower than the lateral one, but does not extend 
so far towards the front; the ventral plate also ends in 
four spines, of which the middle ones are a good deal the 
longer; the lateral space is rather broader than the middle 
one, and extends more to the front; the outer angle of this 
plate is scarcely produced. 

In the male the dorsal plate of the 7th segment ends in 
four short and approximate spines, of which the middle 
ones are longer than the lateral ones; the ventral plate of 


Staphylinide of the Amazon Valley. 89 


the same segment bears a notch in the middle at the ex- 
tremity, the hinder angles of which are acuminate, but 
not produced. 

Ega; two individuals, $ and @. 

Obs.—The above description is made from the female 
individual, the male specimen being greatly mutilated ; 
I have some doubts indeed whether it is of the same 
species as the female, for it has the antenne a little shorter, 
and the intermediate joints darker, than in the female de- 
scribed. 


10. Coproporus cognatus, n. sp. Convexus, piceus, niti- 
dus, antennarum basi, pedibusque rufis; capite thoraceque 
leevigatis, hoc basi fere truncato; elytris obsolete punc- 
tatis, angulo externo obtuso. Long. corp. 14 lin. 

Antenne slender, moderately long; blackish, with the 
three basal joints yellowish, the apex of the 11th joint also 
paler; 3rd joint slightly shorter than 2nd; 4th longer than 
broad; 10th about as long as broad. Thorax with the 
base only slightly sinuate on each side, shining, impunc- 
tate. Elytra ample, obsoletely and sparingly punctured, 
with very fine strigosities connecting the punctures; their 
hind angle moderately distinct. Hind body greatly nar- 
rowed towards the extremity. Legs red. Mesothoracic 
carina only a little elevated. 

In the male the dorsal plate of the 7th segment ends in 
four teeth, of which the middle ones project much farther 
back than the side ones; the teeth are but short and the 
lateral interval extends much more to the front than does 
the middle interval; the ventral plate bears a broad but 
not deep angular notch, the sides of which are only indis- 
tinctly sinuate, and its lateral extremities are not pro- 
duced. 

Anana; a single male found by Dr. Trail on the 6th 
September, 1874. 

Obs.—This species is very similar to C. inelusus; it is 
about the same size, but appears a little broader; the an- 
tenn are darker in colour and more elongate. When both 
sexes of each species are known, I have no doubt good 
sexual distinctions will be found. 


11. Coproporus conformis, n. sp. Sat convexus, 
nitidus, rufus, capite, prothoracis disco, antennisque piceis, 
his basi testaceo ; elytris obsolete punctatis, lateribus haud 
impressis, angulo externo obtuso. Long. corp. 14 lin. 


90 Mr. D. Sharf’s Contributions to the 


Antenne moderately long and slender, blackish in 
colour, with the three basal joints yellowish; 3rd joint 
nearly equal to 2nd in length, 4th slender; 4—10 each 
slightly shorter and broader than its predecessor, so that 
the 10th is a little transverse; 11th rather long. Head 
pitchy, shining and impunctate; palpi yellow. Thorax 
with the hind angles only moderately rounded ; the base 
slightly sinuate on each side, shining and impunctate, 
reddish with the dise broadly pitchy. Elytra dark red- 
dish, ample, very finely punctured and reticulated, the 
hind angle not much rounded. Legs slender, red. 
Mesosternal carina only a little elevated. 

In the male the dorsal plate of the 7th seement ends in 
four rather broad sharp teeth, of which the middle ones 
project much farther backwards than the side ones; the 
space separating the middle teeth is not broad, and does 
not extend far forwards; the base of the lateral notch is 
much nearer to the front. The ventral plate bears a large 
deep notch, the sides of which are a little sinuate, and the 
lateral angles acuminate and a little produced. 

A single male was taken by Dr. Trail on the 5th 
November, 1874, but I have no record of the exact 
locality. 

Obs.—Though extremely similar to C. cognatus, I be- 
lieve this will prove to be a distinct species; it is slightly 
narrower, and not quite so convex; the hind angle of the 
elytron is a little less rounded, and the spines on the 7th 
segment in the male are a little longer, and the notch on 
the ventral plate is a little deeper. 


12. Coproporus rufescens, n. sp. Rufo-testaceus, niti- 
dus, glaber, transversim sat convexus, elytris marginem 
lateralem versus late profundeque impressis, angulo externo 
minus rotundato. Long. corp. 14 lin. 


Entirely of a reddish colour and impunctate, except 
that on the elytra are traces of a sparing and very obsolete 
punctuation. Antenne a little thickened towards the 
apex; 3rd joint small; 4—10 differ but little in length, 
each just a little broader than its predecessor, 10th 
scarcely so long as broad; 11th nearly twice as long as the 
10th. Thorax ample, as broad as the elytra, narrowed 
to the front, the hind angles rather obtuse and a little 
rounded; the base nearly truncate, being very little pro- 
duced near the external angles. Elytra one-third longer 


Staphylinide of the Amazon Valley. 91 


than the thorax; close to the outside margin they have a 
broad, deep impression, commencing a little behind the 
humeral angle but continued close to the outer angle, 
which is but little rounded. Hind body short, furnished 
with exserted black setae. Legs concolorous. Mesothoracic 
carina but little elevated. 

In the female the dorsal plate of the 8th segment of the 
hind body terminates in four acute teeth of nearly equal 
length, the three notches between which are very similar 
to one another in breadth and depth. The ventral plate 
of the same segment terminates in four teeth, shorter 
than those of the dorsal plate; the middle notch between 
these is much shorter than the lateral ones, and is, in fact, 
nearly filled up, but is continued forwards as a groove or 
longitudinal impression. 

ga ; two specimens, ?. 

Obs.—I have not been able to restore the hind body to 
its natural elongation in this species, so that the length 
mentioned for the species is only an estimate. 


13. Coproporus tinctus, n. sp. _Convexus, nitidus, tes- 
taceus, antennis ante apicem elytrisque basi fuscis; elytris 
evidenter punctulatis, intra marginem lateralem latius im-

Antennx rather slender, only moderately long, a little 
thickened towards the extremity; the three basal joints 
yellow, the following ones infuscate; the apical one again 
a little paler; 3rd joint about as long as 2nd ; Ath slender, 
a good deal longer than broad; 10th a little transverse. 
Head yellow, impunctate. Thorax very slightly sinuate 
at the base on each side; the hind angles not much 
rounded, yellow, very shining, quite impunctate. Elytra 
yellow, but with the basal portion largely infuscate; they 
are distinctly punctured on the basal portion, but towards 
the apex the punctuation becomes quite obsolete; they 
have a large, distinct impression near to the lateral margin, 
and the hind angle is but little rounded. Hind body in- 
distinctly and not closely punctured. Mesosternal carina 
low. 

In the female the dorsal plate of the 7th segment of the 
hind body terminates in four moderately long teeth ; the 
middle ones project a little farther back than the lateral 
ones, and are rather the more slender; the middle notch 
does not extend quite so far forward as the lateral ones, 


92 Mr. D. Shae Contributions to the 


the ventral plate of the same segment ends in four shorter 
teeth; the middle ones are stout, the lateral ones not 
quite so stout and not projecting quite so far back as the 
middle ones; the middle notch is not deep, and does not 
extend nearly so far forward as the lateral one. In the 
male the ventral plate of the 7th segment ends in four very 
short, stout teeth; the middle ones project much farther 
back than the lateral ones, which are very short; the 
middle notch is angular and small; the ventral plate bears 
a broad, not very deep, angular notch at the extremity. 

Rio Purus, 13th October, 1874; two individuals (¢ and 
i) oes rail, 

Obs.—The male specimen is quite immature, and has 
no dark colour on the elytra, but I have no doubt what- 
ever but that it is of the same species as the female 
described. 


14. Coproporus distans, n. sp. Sat convexus, niger, 
nitidus, antennarum basi, pedibus, elytrorumque apice tes- 
taceis, prothoracis marginibus dilutioribus ; antice impunc- 
tatus, abdomine omnium subtilissime, dense punctulato, 
opaco. Long. corp. 1 lin. 


Antenne moderately long, blackish, with the four or 
five basal joints yellow; of joints 4—10 each is distinctly 
shorter and very slightly broader than its predecessor, the 
4th a good deal longer than broad, the penultimate joints 
transverse; the 11th short and stout. Head _ black, 
shining and impunctate. Thorax blackish, with the mar- 
gins paler and translucent, the base not at all sinuate, the 
hind angles not much rounded. Elytra blackish, with the 
extremity broadly yellowish, shining and impunctate ; they 
are not very convex, but the lateral margin is somewhat 
explanate and very distinct, the hind angle much rounded. 
The hind body is blackish, and is very densely and finely 
punctured, and with an extremely short, fine and delicate 
pubescence. The legs are yellow. The mesosternal 
carina very fine and slightly elevated. 

In the male the dorsal plate of the 7th segment has in 
the middle two extremely short teeth, separated by a 
broad, very shallow notch; the sides of the plate are 
scarcely prominent; the ventral plate bears a broad, shal- 
low notch at the extremity. 

Rio Purus, 25th October, 1874; two individuals found 
by Dr. Trail, one of which, however, has lost the hind 


body.

15. Coproporus duplex, n. sp. Subdepressus, nitidus, 
piceus, antennarum basi, pedibus, prothoracis maginibus, 
elytrisque apicem versus testaceis; antice impunctatus, 
abdomine crebre subtiliter punctulato. Long. corp. 14 lin. 


Antenne elongate, slender at the base, distinctly thicker 
at the extremity; the three basal joints yellow, the rest 
blackish; 3rd joint a little shorter than 2nd; 4th joint 
slender; 10th about as long as broad. Head rather small, 
shining and impunctate, blackish. Thorax very slightly 
sinuate at the base on each side; the hind angles mode- 
rately rounded, the sides and base yellowish, the front 
portion darker in colour ; the surface is shining and im- 
punctate. Scutellum large, impunctate. Elytra but little 
convex transversely, shining and impunctate, pitchy 
yellow, the base darker than the apex; the lateral mar- 
gins explanate; the hind angle a good deal rounded. 
Hind body slender in proportion to the front parts, 
blackish, finely, evenly and rather closely punctured. 
Legs yellow; tibie very slender; the tarsi elongate and 
extremely slender. The mesosternal carina not much ele- 
vated, but with the anterior part more elevated than the 
hinder part, so that an acute projection is formed on its 
middle. 

In the male the dorsal plate of the 7th segment of the 
hind body ends in the middle in two short, stout, acumi- 
nate teeth, and in a scarcely prominent lateral one on each 
side; the ventral plate bears a deep, angular excision, 
the sides of which are a little curved. 

Conceicao, Rio Mauhes; a single male, captured by 
Dr. Trail, May, 1874. 


16. Coproporus scutellatus,n. sp. Subdepressus, nigro- 
piceus, nitidus, antennis pedibusque testaceis, capite pro- 
thoraceque vix visibiliter, elytris subtiliter, abdomine 
evidentius punctatis; elytris secundum marginem lateralem 
canaliculatis. Long. corp. 14 lin. 


This species differs from the others of the genus here 
described by its much flatter and more Tachinoid form, 
and its hind body is evidently less retractile. It appears 
to be closely allied to Z. brevicollis, Er. The antennz 
are yellowish, they are of a moderate length and stout- 
ness, a little thickened to the apex; 2nd and 3rd joints 
nearly equal in length; 4—10 differing but little from 
one another, the 4th considerably stouter than the third ; 


94 Mr. D. Shane Contributions to the 


the 11th joint large, stouter than the 10th, and about 
twice as long. Head broad and short, black and shining, 
extremely finely, almost imperceptibly, punctured. Thorax 
pitchy, paler at the sides, narrowed towards the front, the 
base slightly sinuate on each side, the hind angles rounded 
and projecting a little backwards; it is very finely and 
indistinctly punctured. Scutellum large, smooth and im- 
punctate. Elytra fully a third longer than the thorax, 
straight at the sides, the outer angle not much rounded ; 
they have a deep, narrow channel close to the external 
margin, extending from just below the humeral angle to 
the extremity; they are finely punctured, but more dis- 
tinctly so than the thorax. Hind body rather closely and 
distinctly punctured; segments 2—5 distinctly margined, 
6th and 7th immarginate. Legs yellowish, short ; meso- 
thoracic carina but little prominent. 

In the female the dorsal plate of. the 7th segment ends 
in four stout but long acuminate spines; these project 
about equally far back; the notches between them are 
only narrow, but are elongate; the lateral ones reach a 
little farther forwards than the middle one; the ventral 
plate ends in four shorter and more widely-separated 
spines; of the notches between these the middle one is 
not deep, but the lateral notches extend considerably 
farther forwards than the middle one. 

Ega; a single individual. 


ConuRUS. 


The Tachyporini bearing this name are very easily 
recognized from the fine, delicate pubescence with which 
all the parts of the body are clothed, Species of the 
genus are probably to be found in nearly all countries, 
and, though only five species have yet been described 
from South America, there is but little doubt that these 
insects will be found to be numerous there, for I have 
nine species from the neighbourhood of Rio de Janeiro 
alone in my collection. 


1. Conurus latus,n.sp. Ferrugineus, convexus, pube- 
scens, antennis articulis 5—10 nigris, ultimo pallido basi 
nigro. Long. corp. 2} lin. 

A broad species, very convex about the thorax and 
elytra, with the exception of the antennz of an uniform 
tawny colour. The antenne moderately long, thickened

towards the extremity ; the four basal joints yellowish, the 
six following joints and the base of the 11th blackish, the 
rest of the last joint quite pale. Head small, narrower 
than in C. pubescens. Thorax ample and very convex, 
the sides much narrowed towards the front, the front 
margin very distinctly bisinuate; the hind angles are 
obtuse and rounded, the punctuation and pubescence very 
fine. Elytra about as long as the thorax, their punctua- 
tion and pubescence fine but not dense. The hind body 
is densely and distinctly punctured; its well-marked 
pubescence is of a golden colour. 

The male has a large angular notch at the hind part of 
the ventral plate of the 7th segment of the hind body ; the 
hind margin of the dorsal plate is simple. 

In the female the dorsal plate of this segment is divided 
at the extremity by three narrow elongate incisions into 
four approximate processes, while the hind margin of the 
ventral plate is furnished with long cilia. 

In each sex the front tarsi are rather strongly dilated. 

Ega; two individuals. 


2. Conurus setosus,n. sp. Angustulus, cinnamomeus, 
subtilissime punctulatus et pubescens, abdomine longius 
nigro-setosus; antennis gracilibus, basi apiceque pallidi- 
oribus; prothorace elongato. Long. corp. 13 lin. 

Antenne slender and elongate, pale yellow, a little 
darker in the middle ; 3rd joint about equal in length to 
2nd; 4th slender and elongate; 5—10 each a little broader 
and shorter than its predecessor, 10th slightly longer 
than broad; 11th rather elongate, nearly twice as long as 
10th. Thorax longer than broad, nearly straight at the 
base, the hind angles almost rectangular, but a little 
rounded, the sides curved and a little narrowed towards 
the front, the surface very finely and indistinctly punc- 
tured. Elytra hardly so long as the thorax, similarly but 
a little more distinctly punctured. Hind body slender, 
very finely punctured, furnished with remarkably evident 
long black sete. Legs pale yellow; tarsi elongate and 
very slender. 

Garrao; a single individual found in fungus by Dr. 
Trail, 11th November, 1874. 

Obs.— This individual is, I have no doubt, a male, as 
it has the front tarsi slightly dilated. The elongate black 
setee with which the very slender extremity of the hind - 
body is armed do not allow me to see with certainty the 


96 Mr. D. Shae Contributions to the 


structure of the apical segments; but any peculiarities, if 
existent, must be very slight. 


TANYGNATHUS. 


Of this genus eight species are all that have as yet been 
described, viz., four from the Old World tropics, two from 
the New World tropics, one from temperate Europe, and 
one from the Atlantic Islands. I here add three new 
species to this number, and can state, moreover, that the 
genus will be found ultimately rather rich in species, as 
I have a number of other undescribed ones in my collec- 
tion, one of which is from Southern Australia, and several 
from Brazil. 

The genus is one of very considerable interest ; for it 
was assigned by Erichson to the Tachyporini, by Kraatz 
to the Quediini, and yet possesses certain points foreign 
to both these groups, which appear to me to indicate 
a third relationship with the Aleocharini. A careful exa- 
mination of the structural characters of the species seems 
to me indeed to be urgently needed before its nearest 
relationship can be satisfactorily decided. 


1. Tanygnathus longicornis, n. sp. Rufescens, anten- 
nis elongatis, apicem versus pallidis, elytris piceis ; abdo- 
mine fortiter fere irr egulariter punctato, longius pubescente. 
Long. corp. 24 lin. 

Antennz very slender and elongate, not in the least 
thickened towards the extremity; the basal joint yellowish ; 
the next five or six darker, and the rest again paler. 
Head obscure reddish, very narrow and elongate, smooth 
and shining. Thorax obscure reddish, narrowed to the 
front, not quite so long as broad, with four very fine 
punctures placed as usual in this genus. Elytra darker 
in colour than the head and thorax, scarcely so long as 
the latter, closely and very finely punctured. Hind body 
reddish, with faint iridescent reflections; the base of each 
segment finely punctured; the other part of each segment 
with sparing, rather large elevated points; its pubescence 
rather long, and much mixed with black erect set. 
Legs reddish. 

One specimen; the only locality indicated being 
** Amazons.” 


2. Tanygnathus nasutus, n. sp. Fusco-rufus, antennis 


Staphylinide of the Amazon Valley. 97 


sat tenuibus, medio fuscis, basi apiceque rufo-testaceis ; 
thorace late rufo; elytris fuscis, margine apicali rufo ; 
abdomine dense subtiliter punctato, opaco ; pedibus rufis. 
Long. corp. 24 lin. 

Antenne moderately long, and not very slender; the 
basal joint yellow ; joints 2—7 infuscate, 8—11 yellow. 
Head obscure reddish ; the clypeus in front acuminate. 
Thorax very shining bright red. Scutellum reddish. 
Llytra of a smoky colour, with the hind margin reddish, 
closely and finely punctured. Hind body very obscure 
reddish ; the base rather darker than the extremity, very 
closely and densely punctured, and very pubescent, so as 
to be quite dull. Legs reddish-yellow, underside dull 
obscure red. 

A single individual, without special locality. 

Obs.—This species is about the size of the European 
T. terminalis ; the antenne are of about the same length 
but distinctly stouter; the front part of the clypeus is more 
prolonged, and the punctuation of the hind body is much 
denser. It greatly resembles 7. flavicollis, but has the 
antennee stouter, the clypeus more prolonged in front, and 
the hind body more densely punctured. 


3. Tanygnathus flavicollis, n. sp. Rufescens, capite 
piceo, antennis apice thoraceque flavis, elytris piceo-rufis. 
Long. corp. 14 lin. 

Closely allied to 7. rujficollis, Kr., and about the size 
of that species. Antennz slender, rather long; the lst 
joint yellowish, the next five darker, the rest paler again. 
Head pitchy. Thorax bright reddish-yellow, rather broad, 
of the usual form in this genus, and with the four ordinary 
punctures. . Elytra pitchy; the suture yellowish at the 
extremity, about the length of the thorax, closely and 
finely punctured. Hind body dark reddish, rather closely 
and finely punctured, and distinctly pubescent. Legs 
reddish-yellow. 

Tapajos; one specimen, in bad condition. 


ACYLOPHORUS. 


Up to the present time sixteen species appear to have 
been described of this genus ; they are from widely diffe- 
rent parts of the globe; and the species in my collection 
enable me to state that the genus is probably to be found

in all the warm and temperate parts of the earth’s surface ; 
while in Australia there are to be found some very inte- 
resting forms, apparently intermediate between this genus 
and Quedius. 

The four species here described belong, I think, clearly 
to the same genus as our European species; at any rate, 
their facies is so similar to that of our European species 
that any one acquainted with these would at first sight 
declare the Amazonian species to be congeneric therewith. 
I have several allied species from Brazil in my collection, 
so that the genus will probably prove to be quite as rich 
in species in South America as in any other part of the 
world.

Considerably larger than A. glabricollis. ‘The antennze 
are elongate and slender, with only the two or three apical 
joints a little stouter. The 1st joint dusky yellowish, very 
long, about as long as the five following ; the 2nd and 3rd 
joints about equal in length ; 4th joint considerably shorter 
than the 3rd and a little shorter than the 5th; from the 
5th to the 9th each a little shorter than its predecessor, all 
of these joints elongate; 10th joint much shorter, but as 
long as broad; last joint rounded, nearly as long as the

crossed, dull yellowish. Head broadly ovate, with three 
punctures between the eyes, the middle one the most for- 
ward. Thorax black and shining, rather broad, about 
as long as broad, with the usual four punctures. lytra 
black, scarcely so long as the thorax, with the scutellum 
coarsely, moderately closely punctured. Hind body elon- 
gate, a little iridescent, with a very rigid pubescence ; each 
segment at the extreme base closely and finely punctured, 
the rest of each sparingly and rather coarsely punctured ; 
segments 2—5 with the hind margin furnished with a 
row of very coarse sete projecting backwards ; the extreme

Closely allied to A. glabricollis, rather larger, the head 
narrower; the antennz (the basal joints at any rate) 
longer; and the 6th and 7th segments of the hind body 
entirely black. The antenn are destroyed with the ex-

neck on each side) very close together. ‘Thorax as in 
glabricollis. Scutellum broader than in glabricollis, 
strongly punctured. Elytra scarcely so long as the 
thorax, their punctuation as in glabricollis. Hind body 
much narrowed to the extremity, black, the apex of the 
6th segment concolorous ; each segment is, at the extreme 
base, closely and strongly punctured, the hinder part of 
each much more sparingly. Legs pitchy black; tarsi 
dark reddish. 

Tapajos ; one specimen. 


3. Acylophorus acuminatus, n. sp. Niger, nitidus, 
antennarum basi, pedibusque testaceis, elytris sat crebre

Much smaller and narrower than A. glabricollis. An- 
tenn with the basal half of the Ist joint yellowish, the 
rest pitchy; 2nd joint much longer than the 3rd, 4th 
shorter than the 3rd, 5th longer than 4th; from this to 
the 10th each a little shorter and stouter than its prede- 
cessor, 10th distinctly transverse; last joint stout and 
rounded at the extremity, a little longer than the 10th.

Much smaller than A. glabricollis, and very different in 
colour. Antenne pitchy; the basal portion of the Ist 
joint yellowish; they are moderately long, scarcely 
thickened towards the extremity; 3rd joint much shorter 
than the 2nd, longer than the 4th ; 5th again longer than

QUEDIUS. 


Of this extensive and widely distributed genus it is 
remarkable that I have received but a single species from 
the Amazons, and I have only a few others from South 
America in my collection: as only about five species have 
been described from tropical America, it seems probable 
that the species are not numerous there. 


1. Quedius clypealis, n. sp. Nitidus, rufo-testaceus, 
capite pectoreque piceis, illo antice rufo, abdomine irides- 
centi-nigro, parce punctato basi levi, apice testaceo; ely- 
tris fere levigatis, punctis paucis subseriatis impressis. 
Long corp. 4 lin. 

Antenne short and rather stout, clear yellow; 3rd joint 
longer than 2nd; 4—10 each a little shorter and broader 
than its predecessor, the penultimate joints rather strongly 
transverse, and with their upper and inner angle a little 
produced, so as to be subserrate. Palpi yellow. Head a 
good deal smaller than the thorax, rather short and broad ; 
the eyes very large, and occupying very nearly the whole 
side of the head, shining, blackish, with the front part 
broadly yellow, impunctate, except for two or three punc- 
tures at the margin of the eye. ‘Thorax curved at the 
sides and a little narrowed in front, about as long as 


Staphylinide of the Amazon Valley. 101 


broad, shining reddish-yellow, impunctate, except for 
some punctures along the margins. Scutellum large, 
shining red, impunctate. Elytra as long as the thorax, 
shining red, with two or three not very distinct punctures 
along the suture, with two other punctures near these, 
with a discoidal series of four or five punctures, and with 
a few lateral punctures. Hind body blackish, with irides- 
cent metallic reflection, the hind part of the 6th and all 
the following segment yellow, the lateral styles of the ter- 
minal segment black. Legs reddish-yellow, stout. 

In the male the ventral plate of the 7th segment of the 
hind body has a shallow emargination in the middle of the 
hind margin. 

Ega. 

Obs. I—I have before me eight specimens, which I 
believe to be conspecific, and one of which I have described 
as above. Three of these individuals are males, and agree 
closely with one another, except that in one of them the 
breast isred. The five females differ from the males, inas- 
much as they have the elytra and thorax black, and the legs 
more or less infuscate; whether these differences in colour 
will prove to be sexual, I am unable to say. 

Obs. II.—This species is, to judge from Erichson’s 
description of Q. labiatus, very closely allied thereto, and 
I had at first considered it a variety thereof, but on careful 
examination I think it will more probably prove to be a 
distinct species. 


CorDYLASPIS. 


This genus was proposed by Nordman for a most 
remarkable insect, and it has hitherto remained without 
any known near allies; the extremely rare Scaripheus 
luridipennis connects it unmistakably with Hematodes, 
and I have one or two other undescribed allies in my col- 
lection. The only species yet distinguished is,— 


1. Staphylinus pilosus, Fab. 
Found by Mr. Bates at Parad, Tapajos and St. Paulo. 


PLATYPROSOPUS. 


This genus up to the present time consists of nine or 
ten described species found in the warm portions of the 
Old World. I here add another ten species from the 
Amazons, and consider that they form a most unexpected 
addition to the South American fauna; except these 


all 


102 Mr. D. Sharp’s Contributions to the 


Amazonian specimens, I have never seen another indi- 
vidual of the genus from the New World. 

These new species appear to exhibit the peculiar charac- 
teristics of the genus very highly developed. The struc- 
ture of the front of the head and the insertion of the 
antenne approaches in these species even more to what 
exists in the Xantholini than it does in the Old World 
Platyprosopi ; the antennz are even more approximate in 
their insertion than in the Old World species, and more- 
over the part of the head to which they are attached is 
more prominent, and is a little emarginate on each side of 
the middle, so that the front of the head and the attach- 
ment of the labrum have very much the appearance pre- 
sented by the same parts in the Xantholini. 

The genus is one of the most interesting of the Staphy- 
linide ; it is located by Erichson and Kraatz as a peculiar 
member of the Xantholin?, but I cannot consider that this 
is a correct mode of treating it. The points of structure 
I have already alluded to, viz., the antennal insertion and 
the attachment of the labrum, are almost the only points 
the genus has in common with the Xantholini, while it 
wants some of the most important points of structure of that 
group, and in certain respects approaches to the Quediini 
and even to the Pinophilint. As the group Xantholini 
appears to me one of the most specialized portions of the 
Staphylinide, and as Platyprosopus is pretty clearly of a 
synthetic or little specialized character, it seems to me 
that it will be very much more suggestive of the truth if 
the genus be considered to form of itself a group, to be 
located in the neighbourhood of the Quediini ; for I can- 
not but think that the purposes of inquiry are very much 
better served by the establishment of a considerable num- 
ber of provisional groups, than by slumping together (if 
I may use such a term) under one name a number of hete- 
rogeneous forms, having probably very different genetic 
histories. 


1. Platyprosopus major, n. sp. Parallelus, nigro- 
piceus, capite subopaco, dense punctato, medio spatio 
angusto leevi, nitido; thorace parce punctato, nitido, mar- 
ginibus lateralibus dense fortiter punctatis; elytris ab- 
domineque dense subtiliter punctatis, opacis, fusco-pubes- 
centibus; pedibus fuscis. Long. corp. extens. 10O—12 lin. 


Antenne pitchy, stout, about as long as the head and 
half the thorax; 3rd joint longer than 2nd; 4—10 differ- 


Staphylinide of the Amazon Valley. 103 


ing little from one another, each a little shorter than 
broad; last jomt longer than the 10th, obtusely pointed 
on one side. Head large, quite as broad as the thorax, 
above densely and coarsely punctured, a space along the 
middle free from the coarse punctures, but with a few 
fine and indistinct ones; besides this there are three or 
four still larger punctures on each side mixed with the 
others, and in front of the middle there is a transverse im- 
punctate space; on the underside it is extremely dull, 
densely and finely rugulose-punctate. Thorax as broad 
as the elytra, as long as broad, black, very shining, with 
fine punctures scattered over it, with a dorsal series of 
six punctures on each side the middle, with seven or eight 
other punctures on each side near the front part, and just 
inside the lateral margins, with a narrow strip of coarse 
dense punctuation extending also some way along the 
front and hind margins. Elytra scarcely longer than the 
thorax, densely and finely punctured, nearly opaque, and 
with a very fine fuscous pubescence. Hind body opaque, 
densely and finely punctured, the apical segments more 
coarsely than the others. Legs dusky reddish, very 
pubescent. 

Ega; two specimens, ¢ and ¢. 

Obs.—Besides these two individuals, there is another 
$ specimen from Pebas, which differs in several slight 
particulars and may possibly be a distinct species, but 
more probably is only a local form of P. major. 


2. Platyprosopus laticeps,n. sp. Nigro-fuscus, capite 
prothoraceque disperse punctatis, nitidis, elytris abdo- 
mineque dense subtiliter punctulatis, fusco-pubescentibus, 
opacis; pedibus obscure rufis. Long. corp. 7—8 lin. 


Much smaller than P. major, and without the marginal 
punctuation of the thorax. The antenne are moderately 
stout, and reach about half-way to the back of the thorax; 
they are of an obscure dull-reddish colour; the 3rd joint 
much longer than the 2nd; 4—10 differing but little from 
one another, the 10th about as long as broad. The head 
is quite as broad as the thorax; above it is coarsely, 
irregularly and rather sparingly punctured, the punctures 
less numerous about the middle than at the sides; scattered 
with the coarser punctures are numerous very fine ones; 
on the underside it is quite dull, densely and_ finely 
rugulose-punctate, and with a fine fuscous pubescence. 


or 
104 Mr. D. Sharp’s Contributions to the 


Thorax quite as broad as the elytra, slightly longer than 
broad, on each side the middle with an irregular and not 
very distinct dorsal row of six or seven punctures, and 
between this and the sides with numerous other coarse 
punctures, from which, however, the hinder part is free ; 
besides these it is covered with numerous other very fine 
and distant punctures. The elytra are about as long as 
the thorax, dull, densely and finely punctured, and with a 
very fine pubescence. The hind body is pitchy, with the 
extremity as well as the hind margin of each segment 
ferruginous ; it is densely punctured, and with a fine 
fuscous pubescence. The legs are dull yellowish, very 
pubescent. 
Ega; three specimens. 


3. Platyprosopus parallelus, n. sp. Angustus, piceo- 
ferrugineus, antennis pedibusque obscure rufis, abdomine 
seomentorum marginibus, anoque ferrugineis; capite pro- 
thoraceque disperse punctatis, nitidis; elytris abdomineque 
opacis, dense punctatis, fusco-pubescentibus. Long. corp. 
6 lin. 


Closely allied to P. laticeps, smaller and narrower. The 
antenn are moderately stout, and reach about half-way 
to the back of the thorax; jot 3 much longer than 2; 
4—10 differing but little from one another, each about as 
long as broad. Head slightly narrower than the thorax, of 
a pitchy colour, with two kinds of punctuation on the upper 
surface, viz., a fine punctuation visible on the middle as well 
as elsewhere, and some other larger and scattered punc- 
tures wanting on the middle part. Thorax as broad as the 
elytra, of a pitchy colour, about as long as broad, on each 
side of the middle with an irregular and indistinct row of 
six or seven punctures, and between this and the sides with 
some other punctures, wanting towards the base; besides this 
numerous extremely fine and small punctures are scattered 
on the upper surface. Elytra about as long as the thorax, 
of a pitchy colour, quite dull, densely and finely punctured, 
and with a very fine fuscous pubescence. Hind body 
quite dull, pitchy, the extremity and the hind margin of 
each segment dull reddish, extremely finely and densely 
punctured, and with a very fine pubescence. Legs 
yellowish, very pubescent. 

Ega ; one specimen.

Antenne rather slender, a little shorter than head and 
thorax, dull yellow; 3rd joint one and a half times the 
length of the 2nd; 4—10 each just a little shorter and 
stouter than the preceding one, 4th longer than broad, 
10th about as longas broad. Head pitchy, above coarsely 
and rather closely punctured, the punctures closest about 
the hind angles and front part, the middle of the vertex 
free, but with a few very fine and obsolete punctures ; be- 
neath it is very opaque, from its very fine and dense rugulose 
punctuation. Thorax pitchy red, very shining, about as 
long as broad, sparingly punctured, the punctures con- 
sisting of a row of five or six on each side the middle, and 
fifteen or twenty others on each side of these towards the 
front part. Elytra quite as long as the thorax, dull red, 
closely and finely punctured. Hind body of a pitchy 
colour, the extremity and margins of the segments reddish ; 
it is very finely punctured, and with a very dense fine 
pubescence. Legs yellow. 

Tapajos; two specimens.

seriatim punctato, et versus latera anterius punctis 
nonnullis; elytris abdomineque dense subtiliter punctatis, 
opacis. Long. corp. extens. 44 lin. ; lat. 3 lin. 


Very narrow and parallel. Antenne rather slender, 
1 lin. in length ; red. Head rather darker than the other 
parts, narrow, coarsely punctured, the punctures wanting 
on a space down the middle except at the anterior parts. 
Thorax longer than broad, straight at the sides, just as 
broad as the elytra; reddish, shining, bearing only a few 
punctures, viz., a series of about four large punctures on 
each side of the middle, and a few other large punctures 
between these and the outside towards the front. Elytra 
scarcely longer than the thorax, of an obscure reddish 
colour, densely and finely punctured and densely pubes- 
cent. Hind body rufo-fuscous, densely and finely punc- 
tured and densely pubescent. Legs yellow; underside of 
head very densely sculptured and opaque.

A single female of this species was brought back by 
Dr. Trail; it was attracted by light at Manaos, in August, 
1874. 

Obs.—This species is extremely closely allied to P. 
puncticeps, but is a little smaller, is narrower and more 
parallel ; the elytra and hind body are a little more closely 
and finely punctured, while the punctures on the head and 
thorax are slightly coarser than in the larger species. 


6. Platyprosopus minor, n. sp. Angustus, obscure 
rufus, antennis pedibusque testaceis; capite dense subti-

red, densely and obsoletely punctured, and very finely 
pubescent. Hind body pitchy red; the hind part and the 
extremities of the segments paler, very dull, very densely 
and finely punctured, and with a dense fine pubescence. 
Legs yellow.

finely punctured and pubescent, the middle parts much 
more sparingly so; the underside quite dull and finely 
pubescent ; it is of a pitchy or pitchy-red colour. Thorax 
as broad as the elytra, rather longer than broad, of a dark- 
reddish colour; a space along the middle, and another of

other parts rather sparingly and irregularly punctured. 
Elytra about as long as the thorax, reddish, very densely 
and finely punctured, with a dense very fine fuscous 
pubescence. Hind body pitchy; the extremity and the 
margins of the segments reddish, very densely and finely 
punctured and densely pubescent. Legs yellow. 
Ega, Tapajos, St. Paulo; six individuals.

torum marginibus, anoque ferrugineis 5 capite omnium 
dense subtilissimeque punctato, pubescenteque, peropaco. 
Long. corp. 54 lin. 

The sculpture of the upper surface of the head at once 
distinguishes this species from the others here previously 
described. The antenne are rather long and slender, 
about as long as head and thorax, dull yellow; 3rd joint 
much longer than 2nd; 4—10 each a little shorter than 
the preceding one, the 10th rather longer than broad. 
Head about as broad as the thorax, nearly black, quite 
dull, very densely, evenly and finely punctured and pubes- 
cent. Thorax pitchy, slightly longer than broad, rather 
closely punctured, a narrow line along the middle free 
from punctures. Elytra quite as long as the thorax, dull 
reddish, very finely and densely punctured and pubescent. 
Hind body dusky, with the margins of the segments and 
its extremity reddish, very densely and finely punctured 
and pubescent. Legs dull yellow.

a very fine punctuation and pubescence, which render it 
quite opaque. Thorax dark red, only slightly longer than 
broad, straight at the sides, shining, but at the front angles 
densely and finely punctured, near the middle sparingly 
and rather coarsely punctured, along the middle itself a 
rather broad, but not sharply-limited, space, free from 
punctures; this space bounded on each side by an irregular 
longitudinal patch of coarse punctures; the basal portion 
of the surface free from punctures. Elytra dark reddish, 
as broad as and only a little longer than the thorax, 
densely and finely punctured, and clothed with a very 
fine, short, dense, yellowish pubescence. Hind body fus- 
cous, becoming redder towards the extremity, very densely, 
finely and evenly punctured, and clothed with an extremely 
fine and dense-yellow pubescence. Legs reddish-yellow. 
A single individual, captured by Mr. Bates, and bear- 
ing no special locality, but probably from Tapajos. 
Obs.—This species is extremely similar to P. opacifrons, 
but has the thorax much less densely and regularly punc- 
tured, and the pubescence with which the upper surface 
is clothed is rather denser, finer, and brighter in colour. 


10. Platyprosopus similis, n. sp. Rufo-fuscus, thorace 
nitido, pedibus testaceis; capite, elytris, abdomineque 
dense subtilissime punctatis, et griseo-flavescenti pubes- 
centibus; thorace ad angulos anteriores dense, subtiliter, 
disco parcius fortiter punctato; medio, spatio longitudinali 
minus discreto, impunctato. Long. corp. 6 lin. 


Thorax just as broad as long; elytra a little longer 
than the thorax. 

A pair, ¢ and , of this species were brought from 
Manaos by Dr. Traill; they were attracted by light in 
August, 1874. 

Obs.—This species is so extremely close to P. frontalis 
that a special description is unnecessary ; it is rather larger 
and distinctly broader, and its colour is not so bright; the 
impunctate area on the middle of the thorax is also not 
quite so distinct. The different punctuation of its thorax 
will distinguish it from P. opacifrons, to which species it 
is also extremely similar. 


BRACHYDIRUS. 


This genus consists at present of five described species, 
to which I now add nine others. It is quite peculiar to 
South America, and was established by Nordmann for a 


Staphylinide of the Amazon Valley. 109 


Brazilian species, but was not considered valid by Erich- 
son, who relegated Nordmann’s species to the genus 
Staphylinus, and described two or three allied species. 
Kraatz, however, has re-affirmed the validity of the genus, 
and pointed out some of its important structural points. 
In point of fact, the genus seems at present to me a really 
distinct and isolated one. The structure and form of the 
head, and insertion of the antennze, as well as some points 
in the formatron of the prothorax, bring the genus into 
proximity with the Aleocharini, but it seems probable 
that the points alluded to indicate a functional, and not a 
genetic, relationship. 

The species appear to be very rare in collections, so 
that it is quite possible they may have some peculiar mode 
of life.

than 3rd; 5th a little shorter than the 4th; 6—10 differ- 
ing but little im length, but each a little broader than its 
predecessor, 6 and 7 about as long as broad; 8—10 trans- 
verse ; 11th joint rather large, about twice as long as the 
10th. Mandibles and palpi yellowish. Head black, near 
the vertex with two indistinct reddish spots; it is as broad 
as the thorax; all the front is coarsely and very densely 
punctured, the vertex more sparingly so; it is clothed with 
very fine and rather scanty, but longish, yellow-grey pubes- 
cence. ‘Thorax narrower than the elytra, about as long as 
broad; the base and hinder angles rounded, the sides a 
little sinuate; so that it is a little broader in the front part ; 
it is black and shining, with large, irregularly placed 
punctures, so arranged as to leave a narrow space at the 
base, a longitudinal space along the middle, and an obscure 
elevation near the front angles, free from punctures. Scu- 
tellum closely and rather finely punctured, and with a grey 
pubescence. Llytra a little longer than the thorax, black, 
with a faint bluish tinge; moderately coarsely and not 
closely punctured, with a very fine pubescence. Hind

of the 6th segment and the whole of the 7th bright yellow ; 
the 2nd segment is nearly impunctate; 3—6 moderately 
closely and distinctly punctured, 7th very finely and 
sparingly; 3rd, 4th and 7th segments with a yellowish, 
the others with a blackish pubescence. ‘The front legs are

pitchy, the middle legs blackish, with the lower half of 
the femora yellowish. Hind legs black. 

In the male the 6th segment is, on the underside, a little 
emarginate in the middle; the 7th with a rather deep and 
narrow notch, on each side of which the hind margin is 
just a little prominent. Lateral lobes of the 8th segment 
broader towards the extremity, instead of being pointed as 
usual, 

Ega; eight individuals. 

Obs.—This species is probably rather closely allied to 
B. xanthoceros, Nord. I have a female specimen from 
Peru in my collection, which I believe is conspecific with

Mas: abdomine segmento sexto ventrali apice medio 
emarginato, 7° triangulariter producto, apice ipso emargi- 
nato. 

Antennz short, distinctly thickened towards the end; 
Ist joint yellowish at the base, fuscous towards the ex- 
tremity; 2—5 fuscous, 6—9 pale yellow, 10 and 11 
fuscous, 2nd and 3rd of about the same length; 6th joint 
about as long as broad, 7—10 transverse, the 10th rather 
strongly so; 11th long and pointed. Head with the eyes 
a little broader than the thorax, the front half very densely 
and coarsely, the hinder half much more sparingly punc- 
tured, finely and sparingly pubescent; mandibles and palpi 
pitchy. Thorax much narrower than the elytra, about as 
long as broad, its width greater in front than behind; it 
is black and shining, irregularly and very coarsely punc- 
tured, the punctures so disposed as to leave a narrow por- 
tion at the base ; a line along the middle, and an obscurely 
elevated space near the front angles, free. Scutellum 
rather closely punctured. Elytra longer than the thorax, 
rather coarsely punctured. Hind body distinctly narrower 
towards the extremity, black, with the hinder portion of 


Staphylinide of the Amazon Valley. Lid 


the 6th and the whole of the 7th segment bright, reddish- 
yellow; segments 3—6 sparingly punctured, 7th nearly 
impunctate; the pubescence is scanty, and is yellowish on 
segments 3—5. Front legs yellowish, with the coxe and 
base of the femora pitchy; middle legs dusky yellow, 
their tibize rather darker; hind legs nearly black, with the 
tarsi ferruginous. 

In the male the 6th segment beneath has the hind mar- 
ein emarginate in the middle; the 7th is triangularly pro- 
duced in the middle, but instead of being pointed has a 
small notch at the extremity. 

Kiga; four specimens, 3 ¢, 1 2.

domine nigro, ano pedibusque testaceis. Long. corp. 43 lin. 

Mas: abdomine segmento sexto ventrali apice medio sat 
profunde semicirculariter emarginato, 7° carinato-com- 
presso, in stylo tenui apice bifido producto. 


Antenne yellow, rather short, thickened towards the 
extremity ; 2nd and 3rd joints about similar in length; 
6th joint about as long as broad, 7—10( transverse; last 
joint moderately long and pointed. Head a little broader 
than the thorax, very short; the front part extremely 
densely, the vertex more sparingly punctured. It is of a 
tawny-yellow colour, with an extremely fine pubescence. 
Thorax rather shorter than long, a little broader in front 
than behind, the sides a little sinuate; like the head and 
elytra, it is of a tawny-yellow colour, coarsely and irregu- 
larly punctured, with the usual smooth spaces. Elytra 
considerably longer than the thorax, rather coarsely punc- 
tured, with a distinct concolorous pubescence. Hind body 
narrower at the extremity, black, with the hind margin of 
the 6th segment and the whole of the 7th yellow; lateral 
lobes of the 8th black; 2nd segment impunctate, 3—6 
moderately punctured, 3 and 4 with a yellowish pubes- 
cence. Legs yellow. 

In the male the 6th segment of the hind body beneath 
has a broad and rather deep semicircular incision; the 
ventral plate of the 7th segment is most remarkably 
formed, being compressed into a sort of keel, and produced 
behind as a slender tongue, the extremity of which is 
divided into two still more slender, skort styles. 

In the female the ventral plate of the 7th segment is a 
little produced, and is pointed at the extremity; in this 


112 Mr. D. Shafp’s Contributions to the 


sex also the head is rather less closely but more coarsely 
punctured than in the male. 

Ega; eleven individuals. 

Obs.—The peculiar structure of the ventral plate of the 
7th seement shows no variation in a series of six ¢ indi- 
Vv iduals.

tato. Long. corp. 44 lin. 

Mas: abdomine segmento sexto ventrali apice medio 
obsolete emarginato, segmento 7° subtriangulariter inciso. 


Antenne ie rather short and stout, much 
thickened towards the extremity; joimts 2 and 3 about 
equal, 4th longer than the 5th end 6th, these two short ; 
the 6th transverse, 7—10 strongly transverse; 11th long, 
stout and pointed. Head tawny, coarsely and densely 
punctured, the punctuation more sparing on the vertex. 
Thorax not quite so long as broad, distinctly broader in 
front, and with the sides a little sinuate, its upper surface 
extremely closely and deeply punctured; the punctures 
are numerous and close, and leave a ver y narrow line at 
the base, a central line, and a spot near the front angles, 
smooth. LElytra considerably longer than the thorax, of 
a similar colour to it, and the head coarsely and rather 
closely punctured, with their pubescence rather coarse and 
distinct. Hind body narrowed towards the apex, black, 
with the extremity of the 6th segment, and the whole of 
the 7th, yellow; the 2nd segment is impunctate, sezments 
3—6 closely and finely easels and densely pubescent ; 
the pubescence on segments 3 5 yellow, 7th segment 
nearly impunctate ; 8th segment with its lateral lobes pale 
at the base, tawny brown at the extremity. Legs yellow. 

In the male the hind margin of the 6th segment of the 
hind body is slightly emarginate, and the 7th has a rather 
narrow and moderately deep notch in the middle of the 
hind margin; in the female the hind margins of the 6th 
and 7th segments are simple, that of the 7th being gently 
rounded ; the last joint of the antennz seems to be shorter 
in this sex than in the male. 

Ega and St. Paulo; seven specimens.

Antenne yellow, short, a good deal thickened towards 
the extremity ; 4th and 5th joints similar to one another, 
not at all transverse ; 6th joint a little transverse, 8—10 
strongly transverse, 11th moderately long. Mandibles 
pitchy. Head with the upper surface largely of a metallic- 
green colour; the vertex however tawny; densely and 
coarsely punctured, the punctuation distinctly less dense 
on the vertex than on the anterior portion. ‘Thorax a 
good deal narrower than the elytra, with rather coarse and 
numerous punctures, distributed in the usual manner. 
Elytra a good deal longer than the thorax, and, like it, 
of a tawny colour. Hund body black, with the hind part 
of the 6th and with the 7th segment yellow; the lateral 
lobes of the 8th segment black; the 2nd segment is im- 
punctate, and has a few yellow hairs on each side; 3rd 
segment sparingly punctured, and with yellow hairs on 
each side; 4th and 5th rather sparingly punctured, much 
clothed with pale hairs; 6th segment more closely, 7th 
very sparingly, punctured. 

In the male the hind margin of the ventral plate of the 
6th segment is emarginate, while the next segment bears 
a narrow, rather deep notch in the middle. In the female 
the hind margin of the ventral plate of the 7th segment 
forms a very obtuse angle in the middle. 

Three individuals, 2 $, 1 2, found by Mr. Bates; the 
male specimen described is labelled Para. I have also 
a male individual of the species labelled Peru in my col- 
lection; it differs only very slightly from the Para indi- 
vidual.

front, more sparingly on the vertex. Thorax rather 
broader than long, yellowish, coarsely and irregularly, but 
rather sparingly punctured, with the usual smooth spaces ; 
it is a good deal broader in front than behind, and con- 
siderably sinuate at the sides. Scutellum large, rather 
finely and closely punctured and pubescent, Elytra 
longer than the thorax, rather coarsely and closely punc- 
tured, and with a coarse pale pubescence. Hind body 
narrowed towards the extremity, black, with the hind part 
of the 6th segment, and the whole of the 7th, yellow; 2nd 
segment impunctate ; 3rd to 6th rather closely and finely 
punctured and densely pubescent, the pubescence on seg- 
ments 3—5 yellowish. Legs pale yellow.

Long. corp. 4—43 lin. 

Mas: abdomine segmento sexto ventrali medio emargi- 
nato, segmento 7° triangulariter producto, apice carinato- 
compresso. 

Antenne rather short, thickened towards the apex; first 
four or five joints pale yellow, the rest blackish, the extre- 
mity of the 11th joint being again paler; 6th jomt con- 
siderably stouter than the 5th, about as long as broad, 
7—10 strongly transverse; 11th joimt pointed, stout and 
rather long. Head broader than the thorax, with the 
palpi pale yellow; the mandibles pitchy; the labrum, and 
a space behind it (not reaching to the eyes on each side), 
black, the rest tawny; it is coarsely punctured, the punc- 
tures on the front part not so dense as in the other species, 
and rather irregular, the hinder part (broadly) more 
sparingly punctured. Thorax about as long as broad, 
much sinuate at the sides, the front markedly broader than 
the hind part, very coarsely and rather sparingly punc- 
tured, with the usual smooth spaces. Scutellum closely 
and moderately finely punctured. LElytra considerably 
longer than the thorax, coarsely, deeply and rather closely 
punctured. Hind body black, with the 7th segment and 
hind part of the 6th pale yellow, finely but not densely 
punctured, the yellow portion almost impunctate; the 3rd 
and 4th segments and the sides of the 5th with the pubes- 
cence yellow. Legs pale yellow. 


Staphylinide of the Amazon Valley. 115 


In the male the 6th segment of the hind body beneath 
is a little emarginate behind. The 7th segment has the 
hind part much produced and pointed, and is compressed 
in a keel-like manner as it approaches the extremity. 

ga; four male individuals. 

Obs.— Besides these four males, I have a single indi- 
vidual from the same locality, which I believe to be the 
female of B. Batesi; the ventral plate of the 7th segment 
is distinctly produced, and its hind margin is simply 
rounded; the antennz are slightly shorter and more cla- 
vate than in the other sex.

Mas latet. 

Antennx short, thickened towards the extremity, 
blackish, the base of the 1st joint yellowish; 5th and 6th 
joints small and short, but scarcely transverse, 7—10 
rather strongly transverse. Palpi and mandibles dark. 
Head above black, with the vertex fulvous, coarsely and 
very densely punctured, the vertex more sparingly than 
the front part. Thorax tawny, with the very coarse and 
close punctures distributed in the usual manner. Elytra 
rather longer than the thorax, rather coarsely punctured, 
similar in colour to the thorax. Hind body black, with 
the 7th segment and hind part of the 6th yellow, the 
styles of the 8th segment dark tawny ; segments 4, 5 and 6 
are rather closely punctured, and 4 and 5 bear pale hairs, 
as also do 2 and 3 near the lateral margins. Legs yel- 
lowish, with the femora, except at the knees, slightly in- 
fuscate ; front legs rather long and slender. 

In the female the hind margin of the ventral plate of 
the 7th segment is simply rounded. 

Para; a single female. 

Obs.—Though closely allied to B. Batesi, I have no 
doubt this is a distinct species; the antennz are shorter 
and darker in colour at the base, the black colour covers 
a larger portion of the head, which also is more densely 
punctured, the coarse punctures of the thorax are more 
crowded together, and the anal styles are paler in colour.

tallic part very dense, and finer than in the other species 
here deseribed; the tawny part much more sparingly 
punctured. Thorax about as long as broad, slightly 
sinuate at the sides, and with the front part a_ little 
broader; its upper surface very coarsely, and, with the ex- 
ception of the usual smooth spaces, rather closely punc- 
tured. Elytra coarsely and moderately closely punctured, 
like the thorax of a tawny colour. Hind body narrowed 
towards the extremity, black, with the 7th segment and 
hind part of the 6th yellow; 2nd segment impunctate, 
3—6 rather sparingly punctured, 3—5 with a yellow 
pubescence at the side parts. Legs yellow, with the 
femora infuscate ; the sternum pitchy. 

In the male the hind body beneath has the 6th segment 
a little emarginate at the extremity, and the 7th segment 
has a rather deep and narrow triangular notch. 

Ega ; one specimen (¢). 


PLOCIOPTERUS. 


This genus consists of six described species, and I here 
characterize ten new ones. The five species known to 
Erichson were described by him under the generic name 
of Staphylinus, and it is to Kraatz that we are indebted 
for the name and some of the characters of the genus; 
these insects are undoubtedly most allied to Brachydirus, 
but the structure of the antenne and front feet seem to 
afford satisfactory points of distinction. 

The species are confined to tropical America, and those 
I possess are easily referable to two sections, in one of 
which the front tarsi and tibiz are simple in each sex, 
while in the other section they are more or less dilated, at 
any rate in the males, and the hinder face of the front 
tibiz is cut away in a peculiar manner near the extremity. 
Three of the species here described were indicated as being 
captured in fungus, which, however, they probably fre- 
quent for predaceous purposes. 


Staphylinide of the Amazon Valley. 1G iy 


In this genus the sexual characters become remarkable, 
and are well worthy of study, for they appear to me to 
suggest the functional result of some very remarkable 
modifications. The specimen of P. T'raili here described 
was received by me in spirit in very fresh condition ; and 
by dissecting out the apical segment, and mounting it im- 
mediately in Canada balsam, the structure of the hard and. 
soft parts of the intromittent organ are finely displayed, as 
well as their position in relation to the lateral valves.

Antenne slender, elongate, black, with joints 8—11 
pale yellow; 3rd joint very long, about twice as long as 
the 4th; 4th about equal to 2nd in length; 11th joint 
oblong, longer and narrower than the preceding one. 
Head broader than the thorax, black, shining, coarsely 
and irregularly punctured ; the punctures so disposed as to 
leave a small triangular space behind the labrum, and a 
large irregular space on the disc, free; the punctures armed 
with fine greyish sete. Mandibles and palpi elongate, 
black or pitchy-black. Thorax about as long as broad, 
much narrower than the elytra, a little narrowed behind, 
the hind angles quite rounded, the sides scarcely sinuate ; 
it is black and shining, coarsely and irregularly punctured, 
a broad irregular smooth space in the middle free; the 
punctures are finer at the sides. Scutellum large, dull, 
closely and finely punctured, clothed with a dense grey 
pubescence. Elytra longer than the thorax, blue, rather 
closely and finely punctured, clothed at the base and apex 
with a dense grey pubescence. Hind body narrower 
towards the extremity, black, with the 6th and 7th seg- 
ments bright yellow; 2nd segment impunctate, 3rd finely 
and rather closely punctured, and clothed with a grey 
pubescence; 4 and 5 finely and not closely punctured,

with a fine black pubescence; 6th finely punctured, 7th 
more sparingly and finely punctured, these two with a 
concolorous yellow pubescence. 

Legs black, with the tarsi obscure reddish. 

In the male the 6th segment on the underside is fur- 
nished in the middle with a line of very long projecting 
hairs, and the hind margin is slightly emarginate ; the 7th 
segment has a large triangular notch; the w«deagus is 
large, and is furnished with a stout ligula projecting far 
beyond the body of the organ and bifid at the extremity. 
In the larger individuals of this sex the mandibles and 
palpi are more elongate, and the elytra are furnished near 
the outside with a longitudinal fold or plica of variable 
length ; this is quite absent in the smaller males. The 
anterior tarsi are quite simple. 

Ega; nine specimens. 


2. Plociopterus fungi, n. sp. Niger, nitidus, abdo- 
minis apice rufo-testaceo; elytris cyaneis, fasciatim cinereo-

Long. corp. 7 lin. 


This species is almost the same as P. tricolor in most 
respects, but it has only two joints at the apex of the 
antennz white, and the male characters are a little diffe- 
rent. 

In the male the 6th segment is on ‘the underside, 
furnished across the middle with a curved line of long 
projecting hairs, and its hind margin is rather deeply 
emarginate; the 7th segment bears a large triangular 
notch. The edeagus is similarly formed to that of 
P. tricolor, but its elongate ligula is less produced, and 
the bifid processes at its extremity are shorter and more 
rounded. . 

Paré; a single specimen found by Mr. Bates; it is 
labelled “ stump fungus.” 

Obs.—As I have dissected out the wedeagus in three 
males of P. tricolor, and find its form to be completely 
similar in the three, I cannot consider this individual to 
be a mere variety of the Ega species.

Antenne moderately long, blackish, the last three joints 

ellow ; 3rd joint twice as long as 2nd, 4th a little longer 
than the 2nd. Mandibles and palpi pitchy. Head above 
blue, slightly broader than the thorax, very coarsely 
punctured, with a triangular space behind the labrum, and 
a small central one, impunctate; pubescence and setzx 
rather long, underside black and impunctate. Thorax 
bluish above, a little longer than broad, a little sinuate at 
the sides, a little narrowed behind, very coarsely punctured, 
with a medial line impunctate; pubescence long, scanty 
and fine, grey. Scutellum dull, finely punctured and 
pubescent. Elytra longer than the thorax, moderately 
closely and not finely punctured, at the base and apex 
with grey pubescence. Hind body narrowed towards the 
extremity, black, with the 6th and 7th segments bright 
yellow; 2nd segment impunctate, 3—5 rather sparingly 
punctured, 3rd with a grey pubescence. Legs black, 
tarsi pitchy. 

In the male, on the underside, the 6th segment of the 
hind body has in the middle, near the base, a short trans- 
verse impression or fovea, bearing some long, fine hairs; 
the 7th segment is furnished in the middle of the hind 
margin with a broad shallow notch or emargination. The 
eedeagus is small, and furnished with a ligula shorter than 
the body of the organ, and so slender as to be easily over- 
looked. ‘The front tarsi are simple. 

St. Paulo; one ¢ specimen. 

Obs.— Notwithstanding the extreme resemblance of this 
species to P. tricolor, the wdeagus is so different as to 
suggest that the two insects may possibly have to be re- 
ferred to distinct genera.

than the thorax, blue, with ashy pubescence at the base 
and extremity, rather coarsely punctured. Hind body 
black, with ihe 6th and 7th segments bright reddish- 
yellow; the anal styles are yellow at the base, but their 
apical half is quite black; the segments are rather closely

The legs, including the coxz, are black, with the tarsi 
pitchy 5 but having ‘the apical joint reddish. 

Para; a single | “female taken two or three years ago. 

Obs.—This unique specimen, though in bad condition, 
represents, I have no doubt, a distinct species, which will 
be easily distinguished from P. tricolor and P. fungi, by 
the colour of the antennz and the anal styles. Compared 
with a female of P. tricolor it is seen that the antenne are 
much shorter, that the thorax is shorter and more sinuate 
at the sides, and more narrowed behind, and that the 
elytra are shorter and more coarsely punctured.

the three following together. 

The male has the hind margin of the 6th ventral seg- 
ment slightly emarginate in the middle, and the 7th with 
a triangular notch in the middle. The swdeagus is rather 
broad and has the ligula flat and broad, similar in length 
and breadth to the body of the organ, and closely applied 
thereto. ‘The front feet simple.

it distinct therefrom.

body is produced in the middle, the apex of the produced 
part a little emarginate ; on each side of this large middle 
projection is a much smaller projection. On the under- 
side the hind margin of the 6th segment is slightly 
trisinuate ; the 7th segment is a little produced in the 
middle, and has a deep, rather narrow notch in the middle. 
The 8th segment has the lateral lobes modified and irre- 
gular, each is corneous, bluntly pointed at the extremity, 
and there furnished with two stout black sete; before the 
extremity each is distorted and has an irregular broad 
projection, which is black at its extremity, the rest of the 
lobe being pale yellow. The ligula of the zdeagus is com- 
pressed and keel-like, its hinder half furnished with fine, 
black, file-like asperities, it reaches much beyond the body 
of the organ; from the latter projects a small fine appen- 
dage, extending about to the apex of the ligula.

This species is extremely similar to P. /etus, but it is 
smaller and has the head a great deal smaller, and the 
male characters very different. The front tibiz and tarsi 
are similarly formed to those of P. Jetus, but the abdominal 
characters are very different. The dorsal plate of the 7th 
seoment has the hind margin simply rounded. ‘The hind 
margin of the 6th ventral segment is slightly emarginate 
in the middle, and the ventral plate of the 7th segment is 
distinctly produced, and has a well-marked notch in the 
middle at the extremity. The styles of the 8th segment 
are yellow, and are broad at their extremity, which is 
densely fringed with short, black, file-lke seta, and on 
the under face of the style there is an additional short 
series of such setze very close to the extremity. 

Ega ; two males.

tomentosibus. Long. corp. 5 lin. 

Mas: abdomine segmento 7° dorsali margine posteriore 
medio obtuse angulato, angulo ipso exciso; ventrali sat 
producto, apice lato, leviter emarginato. 


Antenne quite as long as head and thorax, pale yellow, 
with joints 6—9 infuscate. Palpi pale yellow; mandibles 
pitchy. Head black, with a very slight greenish reflec- 
tion, very coarsely punctured, but with a large impunctate 
space on the middle; it is just about as broad as the 
thorax. Thorax narrower than the elytra, just about as 
long as broad, shining black, with an irregular series of 
coarse punctures along each side of the middle, and with 
some other coarse punctures between these and the sides, 
and with a short longitudinal impression in front of the 
base in the middle. LElytra slightly longer than the 
thorax, rather coarsely punctured, clothed at the base and 
extremity with pale hairs, which form two not very dis- 
tinct transverse fasciz. Hind body yellow, with the basal 
seoment blackish; the basal segments impunctate, and the 
6th only sparingly and finely punctured. Legs yellow, 
with the coxee black. 

In the male the three basal joints of the front tarsi are 
distinctly dilated; the hind margin of the dorsal plate of 
the 7th segment is a little produced, so that it would form 
in the middle a very obtuse angle, but where the angle 
would be there is a very small excision; the ventral plate 
is distinctly produced in the middle, but the middle part 
is not acuminate, but forms a rather broad lobe, which 
has its hind margin a little emarginate. The styles of 
the 8th segment are yellow, and are broad at their ex- 
tremity, which is very densely set with short, black, file- 
like setae, and both on the upper and under side there is 
an additional short row of such sete very near the 
extremity. 

Garrao; a single male, found in fungus by Dr. Trail, 
on the 11th November, 1874. 

Obs.—This species is very closely allied to P. ventralis, 
but the male characters are a little different, and the 
thoracic punctuation is rather coarser.

Fem.: abdomine segmento 7° et supra et infra medio

This species is very closely allied to the preceding, so 
that it is only necessary to point out the characters dis- 
tinguishing it therefrom. The antenne have the first five 
joints pale yellow, 7—10 nearly black, the 11th again 
pale. The punctures on the thorax are coarser and rather 
more numerous in J. virgineus; the upper side of the 
hind body is distinctly though finely punctured, this being 
especially evident on the ‘3rd and 4th segments. The 
hind body is also narrowed and pointed at the extremity, 
but this is probably a character peculiar to the female. I 
have no doubt the discovery of the male will prove this to 
be a good and distinct species. 

Fonteboa; one ? specimen. 

Obs.—Though this species greatly resembles P. letus, 
P. ventralis and P. Traili, I feel no doubt it will prove 
distinct from all of them: the female is readily distin- 
guished by its sexual characters from the same sex of 
P. letus ; the females of the other two species being un- 
known to me, I can of course make no comparison with 
them.

Fem. latet. 


Antenne slender and rather long, yellow, with the 7th 
and 8th joints infuscate; 3rd joint not quite twice the length 
of the 2nd; 4th not quite so long as 2nd; 11th joint 
rounded at the extremity. Palpi pale yellow, mandibles 
pitchy. Head about as broad as the thorax, above of an 
obscure-greenish colour, and not very shining; all the dise 
free from punctures, and a little convex ; the sides coarsely 
punctured ; a quadrate space behind the labrum depressed, 
and with some very coarse but not well-defined punctures. 
Thorax black and shining, narrower than the elytra, 
transversely convex, its length hardly greater than its 


Staphylinide of the Amazon Valley. 125 


width ; just a little broader in front, and the sides a little 
sinuate ; on each side of the middle is an irregular line of 
about nine punctures, and other punctures are scattered 
along the sides, especially near the front part. Elytra 
about the length of the thorax, blue, with a grey pubes- 
cence at the base and near the extremity, moderately 
closely punctured. Hind body yellow, with the 2nd seg- 
ment darker ; it is almost impunctate, and very sparingly 
pubescent above, beneath distinctly but rather sparingly 
punctured, and with a fine long pubescence. Legs yellow, 
with the coxz pitchy. 

The characters of the male are very complicated and 
most remarkable. The front tibiz are dilated towards 
the apex, and somewhat concave on the inner side; the 
three basal joints of the front tarsi are a little dilated. ‘The 
dorsal plate of the 7th segment of the hind body has three 
sinuses at the hind margin; the middle one is the broader, 
but is not formed by the margin being cut away, but by 
its being turned downwards; at the base of this turned- 
down portion are two sharp teeth, placed near to one 
another ; from the extremity of this turned-down part pro- 
ject two vertical processes. ‘The ventral plate of the same 
segment is a little produced, and has a deep incision or 
notch in the hind margin; along each side of this notch it 
is broadly impressed. The lateral lobes of the 8th seg- 
ment are modified in a most extraordinary manner; each 
terminates in three processes,—a broad, truncate, central 
one, armed on the inner side with two rows of file-like 
asperities, and a long, slender, somewhat curved process 
on each side. The body of the xedeagus terminates in 
a produced point or beak, and is furnished beneath 
with a ligula longer and broader than the beak, and 
densely set with black asperities on each side, towards 
the end. 

Ega; two males. 

Obs.—This species is undoubtedly closely allied to 
St. venustus, Ev., from Cayenne, but I cannot make the ¢ 
characters agree with Erichson’s description. These male 
characters are the most extraordinary I have met with 
in any Coleopterous insect. 


XANTHOPYGUS. 


This genus, like the two preceding ones, is due to 
Dr. Kraatz; but unlike them, it seems to be composed of 


126 Mr. D. shates Contributions to the 


heterogeneous species, and will not improbably undergo 
other changes. The species known to Erichson were 
described by him in part as belonging to the genus Sta- 
phylinus, and in part to the genus Philonthus. About 
sixteen species are described, all from South America. 
I here refer eleven Amazonian species to the genus, of 
which I consider seven new. ‘The species, however, pre- 
sent great difficulties, and I have no doubt some time must 
elapse, and considerable discussion and comparison take 
place, before their limits and characters are fully ascer- 
tained. 


1. Staphylinus sapphirinus, Er. 


This appears to be a common species in the Amazon 
Valley; a fine series before me indicate it as being found 
at Obydos, Tapajos, Ega and Pebas. I think I am correct 
in the name I have assigned to these specimens, for they 
agree well with Erichson’s description (Gen. et Spec. 
p- 364), except that the male has the hind margin of the 
6th segment beneath rather deeply emarginate, while no 
allusion is made to this in the description above mentioned. 
Erichson records the species from Columbia and from the 
Parad in the north of Brazil, but it does not occur, I 
believe, so far south as Rio de Janeiro. 


2. Xanthopygus Solskyi, n. sp. Niger, nitidus, ab- 
dominis segmentis duobus ultimis rufis ; ely tris cyaneis, 
antennis testaceis; abdomine apicem versus crebre punc- 
tato. Long. corp. 7 lin. 


Antenne yellow, 14 lin. in length; 4th joint much 
longer than broad, 10th about as Jong as broad; palpi 
yellow ; labrum pitchy yellow. Head very nearly as broad 
as the thorax, black, with a rather large impunctate space 
on the middle, elsewhere punctured: the punctures not 
coarse nor close. Thorax shining black, just about as 
long as broad, the sides rather sparingly and not coarsely 
punctured, with a rather broad impunctate space along 
the middle, and also in front of the base at the sides. 
Seutellum punctured. Elytra rather longer than the 
thorax, of a dark blue Ptour, moderately closely and 
coarsely punctured. Hind body rather slender, black, 
with the two basal segments entirely reddish-yellow; the 
segments rather coarsely but not altogether densely punc- 
tured; the punctuation much denser on the basal than on 


Staphylinide of the Amazon Valley. 127 


the apical portion of each segment; the 6th rather more 
sparingly punctured than the preceding one. Legs black ; 
front tarsi with the apical joints reddish, and clothed 
beneath with tawny hairs. 

In the male the hind margin of the ventral plate of the 
7th segment is emarginate in the middle, and in front of 
the emargination the surface is shaved away so as to 
form an angular depression. 

Para, one specimen, ¢; Ega, one @. 

Obs. I—This species closely resembles the preceding 
one, but is decidedly narrower, and has the head and the 
thorax and the 6th abdominal segment less densely punc- 
tured, and the male characters different ; besides the ex- 
ternal differences, I may add that the apical portions of 
the edeagus are very much less elongate than in X. sap- 
phirinus. 

Obs. II.—Besides the specimens above mentioned, I 
have several other individuals from Tapajos, Ega and 
St. Paulo, which are, perhaps, varieties of this species, 
but as they are all females I cannot speak certainly: they 
are generally a little larger than the individual described, 
in two of them the elytra are more purple, and in the 
larger specimens the head and thorax are more coarsely 
punctured, and the antenne a little stouter. I have also 
a male individual, found by Mr. Buckley in Ecuador, 
which I have no doubt is conspecific with the Parad male 
from which I have drawn up my description; this speci- 
men has the hind margin of the 6th segment underneath 
a little emarginate in the middle; this point I cannot 
ascertain for the Para individual, as just that part of the 
specimen is slightly broken. 

Obs. III.—I have named this species in honour of 
Mr. Solsky, of St. Petersburg, who has of late years 
published the descriptions of many interesting species of 
South American Staphylinide. 


3. Xanthopygus cyanipennis, n. sp. Niger, nitidus,

corp. 7 lin. 

Mas: segmento 6° ventrali margine apicali medio 
obsolete emarginato, segmento 7° sat profunde triangu- 
lariter emarginato. 

Allied to X. sapphirinus, but considerably narrower, 
the punctuation of head and thorax much more sparing, 


128 Mr. D. shies Contributions to the 


the hind body not nearly so densely punctured,.and with 
the base of the 6th segment black. 

The male differs from that of sapphirinus by wanting 
the transverse pilose line on the 6th segment beneath, by 
having the hind margin of the same segment only obso- 
letely emarginate, and by the different shape of the notch 
of the 7th segment. 

Eea; four male specimens. 

Obs.—This species may, perhaps, ultimately prove to 
be only a variety of X. Solskyi, from which it differs 
almost solely by the dark basal portion of the 7th segment 
of the hind body. In the male the notch of the 7th 
segment is deeper, and the edeagus itself is larger than 
in X. Solskyi; but the former of these characters must 
be, I think, liable to variation, for in one of the individuals 
above mentioned the notch scarcely differs from that of 
X. Solskyi, and yet I can scarcely anticipate that this 
will prove a different species, for the resemblance in other 
respects 1s very great. 


4. Xanthopygus apicalis, n. sp. Niger, nitidus, an- 
tennis testaceis; elytris cyaneis, abdomine segmento 6° 
dimidio apicali, segmento 7° toto rufo-testaceo. Long. 
corp. 5 lin. 

Mas: abdominis segmento 6° ventrali margine apicali 
medio obsoletissime emarginato, segmento 7° late minus 
profunde triangulariter emarginato. 


Much smaller than sapphirinus, with head, thorax 
and hind body more sparingly punctured. Very close to 
X. cyanipennis, and differmg therefrom only by being 
considerably smaller and more slender, and by the broader 
and less deep notch of the 7th segment in the male. I 
have not examined the edeagus. 

Ega; two specimens, ¢, ¢. 


5. Xanthopygus violaceus, n. sp. Niger, nitidus, an- 
tennis testaceis, capite thoraceque violaceis; elytris cyaneis, 
abdomine segmento 6° dimidio apicali, segmentoque 7° 
toto rufo-testaceo. Long. corp. 6 lin. 

Mas: abdominis segmento 6° ventrali medio linea trans- 
versa longe pilosa, margineque apicali minus evidenter

Much smaller than sapphirinus, and readily distin- 
guished by the beautiful violet colour of the head and

thorax. Antenne and palpi entirely yellow. Head rather 
smaller than the thorax, with the disc broadly impunctate, 
the punctures rather coarse and moderately numerous. 
Thorax about as long as broad, nearly straight at the 
sides, the punctures numerous and rather coarse, the 
middle smooth space rather narrow. Scutellum rather 
coarsely punctured. Elytra blue, broader and rather 
longer than the thorax. Hind body densely and rather 
coarsely punctured, the hinder half of the 6th segment as 
well as all the 7th reddish-yellow. Lee's black, front tarsi 
ferruginous. 

The male has on the underside a transverse line of long 
erect hairs in the middle of the 6th segment, the hind 
margin of the same segment slightly emarginate; in the 
middle of the hind margin of the 7th segment is a rather 
deep, abruptly cut-out notch. 

Conceicao, Rio Mauhes, May, 1874, one male; 
Tunantins, 24th November, 1874, one female, found by 
Dr. Trail; also one specimen of each sex brought from 
Ega by Mr. Bates. 

Obs. I.—The female of this species has the antenne a 
little shorter and their penultimate joints more transverse 
than the ¢. 

Obs. I1.—Though this species is closely allied to X. 
sapphirinus, there can be no doubt it is quite distinct 
therefrom. It is worthy of remark that not only do the 
external abdominal characters of the ¢ greatly resemble 
those of X. sapphirinus, but that also the structure of the 
edeagus in the two species is very similar, the ligula 
being in both more detached from the body of the organ 
than in the other species here described. The front tarsi 
are, on the other hand, sufficiently dissimilar in this sex 
of the two species to afford of themselves satisfactory 
characters by which the two may be distinguished; they 
are not so broad and patellated in X. violaceus, and are 
less densely pubescent beneath. 


6. Xanthopygus depressus,n. sp. Subdepressus, niger, 
nitidus, elytris vel viridibus vel cyaneis, abdominis seg- 
mentis ultimis duobus flavis, antennis pedibusque ex parte

middle, the last joint again paler; 3rd joint rather long 
and slender, conside1 ably longer than the 2nd; from the 
4th to the 10th each joint is a little shorter than its pre- 
decessor, the 4th considerably longer than broad, 7th 
about as long as broad, 8—10 rather 1 transverse ; last joint 
pointed, nearly twice as long as the 10th. Palpi yellow, 
mandibles pitchy. Head broad, quite as broad as the 
thorax, coarsely and irregularly ‘punctured, with a broad 
impunctate space in the middle. Thorax about as long as 
broad, a little narrowed behind, with two irregular lines of 
ten or twelve coarse punctures along the middle, separated 
by a rather broad, impunctate space, and with other 
coarse, irregular punctures, especially numerous near the 
anterior angles. Scutellum large, rather strongly punc- 
tured, with a narrow impunetate - margin. Ely tra broader 
than the thorax, and about as long, ereenish or bluish, 
rather sparingly punctured, Hind body narrowed tow ards 
the extremity, black, with the last two segments yellow; 
seoments 2—5 moderately closely and distinctly pune- 
tured, 6th more finely, 7th very finely punctured. The 
four front legs yellow, ‘the hinder ones pitchy : 

The male has a shallow, broad notch in the middle of 
the hind margin of the 7th segment beneath. 

Parad, Ega, St. Paulo, Rio Purus; sixteen individuals. 

Obs.—I judge from the specimens before me that this 
is a variable species; the individual from which the above 
description is taken is a large male from St. Paulo, 
having the head and thorax more coarsely punctured, anid 
the antenn more elongate than in the other individuals. 
The individual from Rio Purus is a small female, having 
the head and thorax sparingly punctured, and is a little 
smaller, narrower, and less depressed than the other speci- 
mens. ‘The two individuals from Para have the front legs 
black, or nearly so, and the antennz rather shorter, while 
one of them has the elytra of a pitchy colour, with blue 
reflections. In the absence of any definite characters to 
separate these forms, I have considered them all as one 
species. 


7. Xanthopygus nigripes, n. sp. Niger, nitidus, an- 
tennis fusco-testaceis, elytris viridi-cyaneis, apdomine seg- 
mentis duobus ultimis flavis. Long. corp. 5 lin. 


Closely allied to X. depressus, and distinguished only 
by the following characters. The head is smaller, being 


Staphylinide of the Amazon Valley. je 3 | 


a little narrower than the thorax; the antenne are dusky 
yellow, and are rather shorter, joint 4 being about as long as 
broad, joints 5—10 transverse; all the legs are black. 
The 6th segment of the hind body slightly darker at the 
extreme base; the head and thorax rather more finely 
punctured. 

St. Paulo; one specimen, ¢. 

Obs.— A second female individual, labelled only Ama- 
zons, departs still more from X. depressus, its head and 
thorax being still more finely and sparingly punctured ; 
but I believe it to be only a variety of X. nigripes. 


8. Staphylinus xanthopygus, Nord. 

I refer to this name a series of individuals, from Ega 
and Pebas; they appear to me to be quite conspecific with 
other specimens from Mexico and central America, and I 
have two or three other closely allied species from other 
parts of South America. The characters of the male are 
not described either by Nordmann or Erichson; in that 
sex the hind margin of the ventral plate of the 7th seg- 
ment of the hind body has a broad but shallow notch in 
the middle, and the front tarsi are slightly more dilated 
than in the female. LErichson names the species Philon- 
thus xanthopygus, but his description does not accord very — 
satisfactorily with Nordmann’s, and I judge it to have been 
drawn up from more than one species. In the Munich 
Catalogue, Nordmann’s species is recorded under the name 
Xanthopygus abdominalis, and it is probable that the 
appellation of the species will be again changed. 


9. Xanthopygus cognatus, n. sp. Subdepressus, niger, 
nitidus, abdomine segmentis duobus ultimis rufo-testaceis. 
Long. corp. 6 lin. 

Closely allied to Staphylinus wxanthopyqus, Nord. 
(Philonthus xanthopygus, Er.), but not half the size 
of that species. Antenne rather short and stout, not 
thickened towards the extremity; the first 3 joints black, 
the rest fuscous ; 3rd joint almost shorter than 2nd, 4th 
and 5th slightly transverse, 6—10 evidently so; last joint 
sinuate at the extremity and pointed. Head short, about 
as broad as the thorax, coarsely and irregularly punctured, 
the middle parts without punctures. Thorax about as 
long as broad, the sides scarcely sinuate behind and very 
little rounded towards the front. Along the middle are

the sides are also numerous large irregular punctures, 
especially numerous towards the front. Scutellum closely 
punctured. Elytra longer than the thorax, moderately 
closely and finely punctured. Hind body black, with the 
extreme hind margin of the 5th segment, and the whole 
of the 6th and 7th segments, reddish-yellow ; the punctua- 
tion moderately close and fine. The legs are stout, pitchy

strongly spinulose.

. Philonthus analis, Er. 


‘a, Obydos, Tapajos, Ega, St. Paulo. 

This appears to be one of the most widely distributed 
and abundant of the South American Staphylinide ; one 
of Mr. Bates’s specimens is labelled as found in dung. 

The male characters are omitted by Erichson: in that 
sex the 6th segment of the hind body has, on the under- 
side on its middle, a small fovea, from which projects a 
slender tuft of elongate hairs, and the following plate has 
a deep but rather narrow notch at the extremity ; the front 
tarsi are moderately dilated in each sex, in the male only 
slightly more than in the female. 


ll. Staphylinus bicolor, Lap. (Philonthus bicolor, Er.).

The male characters in this species also have not been

recorded ; in that sex the ventral plate of the 6th segment 
of the hind body has, near the base in the middle, a trans- 
verse impunctate space, in front of which is another trans- 
verse space which is very slightly depressed and finely 
punctured; the hind margin of the 7th segment is very 
slightly emarginate in the middle; the front tarsi are 
rather broadly dilated and are apparently similar in the 
two sexes, 


PHILOTHALPUS. 


The species referred to this genus are at present nine in 
number, and are confined to South America; they were 
most of them known to Erichson, and divided by him 
among his genera Staphylinus and Philonthus. ‘Three 
others, considered by me as new, are here added. 


Staphylinide of the Amazon Valley. 133 


I have had great difficulty in dealing with this genus 
and its allies, Gastrisus and Eugastus, and feel far from 
satisfied with the course I have adopted. I would have 
preferred considering them all as one genus, containing a 
number of heterogeneous forms, but the characters on which 
the now accepted genera of the Staphylinini are based 
would not allow me to do this; to have dealt with them in 
a satisfactory manner would have necessitated a fresh re- 
grouping of the South American Staphylinini, a step 
which is at present out of the question. On the other 
hand, to have gone backwards and applied to the whole of 
these: insects the name Staphylinus, would, I think, have 
been too retrograde a step. Had there been in use a col- 
lective name to designate all those Staphylinint in which 
the lateral pieces of the thorax are not abbreviated, I 
would gladly have used it for all these insects; but such a 
name has never existed, for Kraatz, to w hom we owe the 
indication of this very important character, when he 
pointed it out, at the same time distributed the species 
possessing it among a number of new genera, while the 
species I am here describing are, many of them, inter- 
mediate between the genera he then characterized. 

The three species here described as appertaining to the 
genus Philothalpus differ considerably from one another in 
facies, and no doubt many entomologists would be inclined 
to consider them as belonging to three distinct genera.

moderately closely punctured, the extremity of each spar- 
ingly punctured ; the upper surface with coarse black 
hair: s, the basal part of the 7th segment without these hairs 
and scarcely punctured. Legs yellowish; basal joint of 
hind tarsi nearly as long as the three fallen ing together.

Obs.—This species I anticipate will prove closely allied 
to Stuphylinus seqmentarius, Kr.; indeed, I should have 
referred these individuals to that species had it not been 
that Erichson describes the apical segment of the hind 
body by the words “ toto nigro,’ Ww eres in P. luteipes it 
is yellow, with the hind margin black. Erichson’s locality 
for S. segmentarius is Columbia, and I have an indi- 
vidual of P. duteipes from Venezuela; should it prove that 
the words I have quoted from Erichson’s description are 
erroneous, it may be probable that P. luteipes is con- 
specific with S. segmentarius.

very nearly to the back of the head. The thorax is about 
as long as broad, rather narrowed behind, the anterior 
angles deflexed and a little rounded, the sides a little 
sinuate behind the middle; it is of a shining tawny colour, 
the upper surface covered with numerous but not coarse

punctures, leaving a central line smooth. The scutellum 
is large, densely and distinctly punctured. The elytra are 
about as long as, and rather broader than the thorax, of 
a tawny colour, moderately closely and rather finely 
punctured. The hind body is rather narrowed to the 
extremity, of a tawny colour, the 5th and 6th segments 
darker and the 7th yellowish; seoments 2—4 finely and 
rather closely, 5th and 6th densely and finely, 7th very 
sparingly and finely punctured. Legs yellowish.

Obs.—This species differs from segmentarius and its 
allies, in that the curved impressions on the basal seg- 
ments of the hind body are so obsolete that they might 
almost be correctly described as absent. The insect 
differs, however, from Lugastus completely in its facies, 
and can therefore scarcely be considered intermediate 
between it and Philothalpus.

The three new species I refer to this genus are very

may possibly prove to be only one species; they suggest, 
at first sight, a comparison with Quedius, but differ there- 
from by ‘the less abruptly-inflexed lateral pieces of the 
thorax. G. punctatus has quite the facies of a diminutive 
Philonthus analis, Er.

Head brassy, moderately shining, with two punctures 
behind the labrum, each placed in a depression, with two 
or three along the margin of the eye, and some others at 
the extreme hind angles ; all the middle part impunctate ; 
it is distinctly narrower than the thorax. Thorax dis- 
tinctly longer than broad, a good deal narrower than the 
elytra, along the middle of an obscure zneous colour, the 
sides and base yellowish; it is distinctly sinuate at the sides 
and a little narrowed behind; on each side the middle, 
at some distance from the front, is a single puncture, 
and two or three others at each front angle, elsewhere 
impunctate. I[ilytra not longer than the thorax, of a 
yellow colour, opaque, sparingly and very obsoletely punc- 
tured, and with scanty fine hairs. Hind body yellowish, 
with the middle of the basal segments infuscate, sparingly

angle of each segment with a long black seta; anal styles 
tawny yellow. Legs yellow, with concolorous spines ; 
basal joint of hind tarsus as long as the three following 
together. 

In the male the front tarsi are moderately dilated and 
furnished beneath with pale pubescence ; the hind margin 
of the ventral plate of the 7th segment bears a small notch 
in the middle.

smaller punctures behind the eyes. Thorax reddish, about 
as long as broad, but little narrowed behind; the sides 
slightly rounded in front, and a little sinuate behind,

Obs.—This 1s very closely allied to G. obsoletus, but is 
a little larger, and has the thorax unicolorous; the head is 
rather larger and a little more elongate, so that the punc- 
tures at the hind angles are rather more numerous and 
more conspicuous.

This genus is undoubtedly very close to Philothalpus, 
but as Kraatz specially bases that genus on the curved 
lines of the hind body, and as these insects do not exhibit 
that character, and as they present a facies strikingly 
peculiar, I have decided on giving a new generic name, 
though with much hesitation. 


1. Eugastus bicolor, n. sp. Rufo-ferrugineus, elytris

10th about as long as broad; last joint about. as long as 
the 4th, pointed on one side. Parts of the mouth red. 
Head as broad as the thorax, orbiculate; the eyes large, 

above red and opaque, with numerous very obsolete punc- 
tures, each bearing a fine upright hair; beneath smooth and 
shining, with a few very fine punctures. Thorax a little 
narrower than the elytra, the length one and a half times 
the width, narrowed eka. transversely very convex at 
the front angles, which are very rounded, the sides a little 
sinuate behind, the hinder angles quite rounded; above 

it is of a very dull-reddish colour, extremely obsoletely 
punctured, but with a rather coarse Ay evenly distr ibuted 
black pubescence. Scutellum very densely pubescent. 

Elytra scarcely the length of the thorax, of an obscure 

dull-bluish colour, w th. an obsolete but rather rugulose 
sculpture. Hind body slender and elongate, a little nar- 
rowed towards the extremity, of a reddish colour; a large 
part of the 5th and 6th segments pitchy, the extremity ‘of 
the 7th also dark, and the basal segments are also a little 
infuscate at the extreme base; the seoments are moderately 
coarsely but not closely punctured ; ; the hind half of the 
6th and the basal part of the 7th very finely and sparingly 
punctured, the styles of the 8th segment blackish. The 
legs are reddish-yellow and rather long, the hind tarsi long 
and slender, the basal jot about twice the length of the 
second.

Antenne with the three basal joints red, the rest 
blackish ; joints 4—10 each distinctly shorter but scarcely 
broader than its predecessor; 4th a good deal longer than 
broad, 10th scarcely so long as broad. Head rather 
narrow, with the eyes very large, of a tawny-red colour, 
dull, covered with an obsolete punctuation, and with a fine 
scanty golden pubescence. Thorax elongate, similar in 
colour to the head, very dull, very obsoletely punctured, 
and with a fine, very depressed, reddish pubescence. Scu- 
tellum velvety-black. Elytra as long as the thorax, of 

a dull-greenish colour, the basal part of their inflexed

portion reddish; they are densely and rather coarsely 
punctured, the punctuation being confluent and rough. 
Hind body with the basal segments blackish, but their 
hind portions tawny; 5th segment entirely black; 6th 
black, but with the hind margin broadly and abruptly 
yellowish ; 7th yellowish, with its hind margin black ; anal 
styles black. Legs tawny yellow. 

A single female of this remarkable species was found by 
Dr. Trail at Lages, near Manaos, on the 5th January, 
1875. <A very mutilated individual of the same sex was 
also sent by Mr. Bates, but without any indication of 
locality. 

Obs.—This species may be readily distinguished from 
FE. bicolor, by its larger size, broader form, and shorter- 
jointed antennze, as well as by the more densely punctured 
elytra and hind body; the two females have the front tarsi 
distinctly dilated, but scarcely so broad as in E. bicolor, &.

being chiefly on their inner sides, so that each of these 
joints is unsymmetrical in shape.

TRIGONOPSELAPHUS ( T'rigonophorus, Nord.). 


This genus is also peculiar to South America; it con- 
sists at present of about a dozen species; some of its 


Stuphylinide of the Amazon Valley. 143 


species are amongst the most brilliant of natural objects. 
Kraatz has remarked that the species fall into three dis- 
tinct groups, adding, that it will be well to leave them 
together in one genus till more species are known. The 
species I here describe as 7. mutator adds yet another 
form to those previously included under this generic name. 
It is well to add, to prevent misconception, that though 
the dilated terminal joint of the labial palpi is given as one 
of the most important characters of the genus, S. venustus 
and violaceus have that joint quite simple, and are allied 
to the Philonthus pretiosus, Er., in this respect.

Obs.—This is a very remarkable species, and one which 
has at first sight the facies of the Xanthopygt with 
metallic elytra; but the labial palpi, and the absence of a 
stigmatic membrane to the thorax, forbid its being asso- 
ciated with them. I have thus been compelled either to 
establish a new genus for it, or to call it a Trigonopselaphus, 
and I have preferred the latter course, as that name has 
already scarcely any definite meaning, owing to the hetero- 
geneous nature of the few species associated under it.

considerably longer than broad, the sides slightly sinuate 
behind the middle, and a little narrowed towards the front 
angles, so that it is scarcely broader at the front than at 
the hind angles; it is similar in colour to the head, and 
has two lines formed of three or four indistinct punctures 
along the middle, and a few other punctures near the front 
part. The scutellum is large, blackish, sparingly and ob-

thorax, very dull, of a blackish colour with a “slightly 
violet tinge, coy ered with rather large and deeply im- 
pressed but distant punctures. The hind body is dis- 
tinctly narrowed towards the extremity; it is of a dull- 
violet colour on the upper side, and is sparingly but dis- 
tinctly punctured. The legs are blackish ; the basal joint 
of the posterior tarsi as long as the three following to- 
gether. The under surface of the imsect is of a “dull- 
blackish colour faintly tinged with violet; the margins of 
the thorax without stigmatic membrane.

Closely allied in structure to Philonthus pretiosus, Er., 
and belonging really to the same genus. Antennz not quite 
so long as the head and thorax, not thickened towards the 
APEX 5 “ond joint long, but shorter than the 3rd; 4th joint 
twice as long as broad, 10th longer than broad, 11th 
rather longer’ than 10th, pointed on one side; they are 
black, with the basal joints violet. Mandibles black, violet 
at fe base. Head a little narrower than the thorax, not 
rounded at the sides, on the upper side of a beautiful 
violet colour, irregularly sprinkled with large punctures, 
the central part being free. Thorax longer than broad, 
much narrower than ie elytra, the sides a : little narrowed 
at the front and sinuate behind the middle; above similar 
in colour to the head, and with an irregular dorsal row of 
ten or eleven punctures on each side the middle, and 
also with other scattered punctures near the front. Scu- 
tellum moderately closely and rather obsoletely punctured. 
Elytra scarcely longer than the thorax, of a dark-violet 
colour, rather finely and closely punctured. Hind body 
distinctly narrowed to the extremity, of a greenish-violet 
colour, rather sparingly and finely punctured, the punc- 
tures evenly distributed. Legs greenish-v iolet; the front 
tarsi dilated in both sexes, the basal joint of the hind 
tarsus not greatly longer than the 2nd.

Staphylinide of the Amazon Valley. 147 


_ Obs.—Philonthus cyanescens, Guérin, is an ally of this 
species, but is very much smaller and has the antenne 
much more slender. 


GLENUS. 


This genus appears to me one of the most distinct of the 
subfamily Staphylinint; the elongate terminal lobe of the 
maxillz, and the mandibles, which though elongate are but 
little curved, taken in conjunction with the subapproxi- 
mate antenne, and the peculiar form of the front of the 
head, give it a peculiar isolation. It consists at present of 
five species, four of which were known by Erichson, and 
assigned by him to his genus Staphylinus, and it is to 
Kraatz that we owe the establishment of the genus. 

I here describe four new species, two of which are very 
closely allied to others already known, while the other 
two, G. amazonicus and G. vestitus, form a distinct sec- 
tion by reason of the unrounded sides of the thorax. 


1. Glenus Kraatzi, n. sp.  Rufo-testaceus, thorace 
cupreo, nitido; elytris aureo-tomentosis, fascia media ad 
suturam abbreviata fusca; abdomine nigro, segmentis sin- 
gulis apice rufis. Long. corp. 12 lin. 

This species is so closely allied to G. biplagiatus, that 
it is only necessary to point out its distinctive characters. 
The punctuation of the head behind the eyes is less close. 
The thorax has the hinder angles less completely rounded 
off, and is a little more sinuate at the sides; the impunc- 
tate medial line is broader, and extends quite to the front 
of the thorax ; its punctuation is less dense, and the small 
punctures mixed with the large ones in diplagiatus are in 
Kraatzi nearly absent. The 3rd segment of the hind body 
is without the transverse curved line which is apparent in 
biplagiatus, and the colouring of the 4th and 5th segments 
is different; in biplagiatus the black marks thereon consist 
of a central spot and another on each side, these being 
united at the base, but distinctly recognizable; in Kraatzi 
these spots are replaced by a broad, transverse band, but 
slightly sinuate behind. 

Ega; one specimen, ¢. 

Obs.—I have much pleasure in dedicating this fine 
species to the learned author of the second volume of the 
** Insecten Deutschlands,” and the founder of the genus to 
which the species belongs. :

marginatis, ‘erebre subtiliter punctatis. Long. corp. 13 lin. 


Closely allied to G. Chrysis, Gray., but distinguished 
therefrom by the redder colour of the pubescence + on the 
thorax and elytra, and by the much more closely and 
finely punctured hind body; the transverse red markings 
of segments 3—5 are ne arly str aight. 

Tapajos ; two specimens. 

Obs.—I have also an individual of this fine species in 
my collection, labelled * Brazil.” A fully extended large 
individual attains sixteen or seventeen lines of length. 


3. Glenus amazonicus,n. sp. Opacus, pube aureo sub- 
tili par clus vestitus, capite rufo-testaceo, ihowmee sericeo- 
zeneo; elytris obscure violaceo-brunneis, ad latera macula 
nigra notatis; abdomine rufo-brunneo, maculis fasciaque 
nigro-zneis. Long. corp. 9 lin. 


Antenne a little shorter than head and thorax ; 3rd joint 
considerably longer than 2nd; 7th joint a little transverse, 
8—10 distinctly so ; 11th joint truncate and sinuate at the 
extremity; they are of an obscure-reddish colour, darker 
towards the extremity, but with the last joint again a little 
paler. Mandibles seddish at the base, black towards the 
extremity; palpi reddish. Head dull reddish, obscurely 
metallic between the antennze, above rather convex ; 
sparingly and very finely punctured, with a fine golden 
pubescence. Thorax much narrower than elytra, consi- 
derably longer than broad, distinctly narrowed behind, 
the front angles rounded and much deflexed, the sides a 
little sinuate ; above it is of a very dull-brassy colour, 
with a very silky lustre; it is sparingly and very obso- 
letely punctured, with a fine golden pubescence, apparently 
very easily removed. Scutellam black, dull and velvety. 
E ly tra not longer than the thorax, of a peculiar dull-red- 
dish colour, with a violet tinge, at the outside with a 
blackish, ill-defined mark; not visibly punctured, and 
with a scanty, depressed, golden pubescence, apparently 
very easily removed. Hind body narrowed to the extre- 
mity, of a reddish colour, marked with black, of a faint 
brassy tinge; 2nd segment nearly entirely black, 3rd with 
a broad mark 3 in the ‘middle and a small one on each side, 
4th and 5th each with a mark in the middle reaching the 


Staphylinide of the Amazon Valley. 149 


hind margin, but not the extreme base; 6th brassy black, 
reddish at the base, 7th entirely yellowish: it is sparingly 
and rather finely punctured, the red parts with golden 
hairs, the black parts with blackish hairs. Legs yellowish- 
brown.

naliter eneo-lineatis. Long. corp. 10 lin. 

Mas: segmento 6° ventrali medio fascicula parva pilorum 
longorum, margine apicali medio leviter emarginato, 7°

Antenne long and slender for this genus, nearly as 
long as head and thorax, of a dull-reddish colour; 3rd 
joint longer than 2nd, none of the joints transverse, 10th 
about as long as broad, 11th about as long as 10th; the 
extremity truncate, with the internal angle much produced. 
Palpi yellowish ; ‘mandibles red at the base, pitchy black 
towards the extremity. Head yellowish, with a metallic 
mark in front between the antenne; it is about as broad 
as the thorax, rather convex above, and clothed with a 
very fine but rather dense golden pubescence. Thorax 
considerably narrower than the elytra, rather longer than 
broad, a little narrowed behind, the anterior angles not 
much deflexed, and but little rounded ; the sides slightly 
sinuate, the hind angles obtuse; it is covered above with 
a dense ferruginous-red pubescence, and has at the anterior 
angles seven or eight long erect, sete. Scutellum densely 
clothed with black velvety pubescence. Elytra about as 
long as the thorax, densely covered with a reddish pubes- 
cence, hiding their colour and sculpture. Hind body nar- 
rowed towards the extremity, reddish, with a brassy line 
along the middle, formed by an elongate spot down the 
middle of each segment; it is closely and finely punctured, 
and rendered dull by a dense, depressed, concolorous pubes- 
cence. Legs yellowish; tarsi pitchy. Breast clothed with 
golden pubescence. 

In the male the 6th segment of the hind body beneath 
has a very short line of long, erect hairs, and the hind 
margin is a little emarginate; the 7th segment has a broad 
and rather deep notch in the middle of the hind margin.

150 Mr. D. Sharf¥§ Contributions to the 


LEISTOTROPHUS, 


This genus consists of a few species, but is of very wide 
distribution. South America possesses but a single species, 
which, however, is the most developed and remarkable of 
the genus. The two species described by Motschoulsky 
under the generic name of Trichoderma, which, in the 
Munich Catalogue, are recorded as South American 
species of Leistotrophus, belong clearly, from Motschoul- 
sky’s description, to the genus Staph ylinus. 


1. Staphylinus versicolor, Grav. 

Para, Ega, Tapajos. 

One of the individuals is labelled as found in cow-dung ; 
the species, like its European congeners, frequents, no 
doubt, putrescent substances for predaceous purposes. 


STAPHYLINUS. 


I have used this name with the same extension as that 
given to it in the Munich Catalogue of Coleoptera, where 
it includes about 100 species, found in all parts of the 
world. It isa genus of which the species are extremely 
closely allied, but yet, studied on the European ones, have 
proved to be incontestably distinct. The exotic species 
are probably extremely numerous, and their discrimination 
will be no easy task. I here enumerate nine species from 

he Amazon Valley, seven of which I have described as 
new; of these the first two, viz., S. swhcyaneus and S. par- 
viceps, are quite distinct, by their combinations of colour 
and sculpture, from any others I am acquainted with. 
The same remark applies to S. gratiosus and S. gratus, 
but S. priscus and S. vetustus are very closely allied to 
the S. antiquus and some other undescribed South Ameri- 
can forms, and thus appertain to what is undoubtedly a 
most difficult group; while the S. amazonicus perhaps 
finds its nearest ally in the North American S. tomentosus. 
It is worthy of notice that Mr. Bates brought back nothing 
to represent the very remarkable S. Buquetii group, of 
which species are found in Mexico, Peru and Brazil; 
will be remarkable if no allied species is found in ite 
Amazon Valley, and yet so large and striking are they, 
that if present one would think they would scarcely have 
been neglected by Mr. Bates during the whole of his long 
residence there.

Mas: abdomine segmento 7° ventrali apice emarginato. 


About the size of S. chalcocephalus, but with the head 
smaller. Antennz about the length of the head and one- 
third of the thorax; they are of a yellowish colour; 3rd. 
joint longer than 2nd, 4—10 transverse, differmg but 
little from one another, 11th sinuate and acuminate at 
the extremity. Mandibles pitchy ; palpi yellow. Head 
smaller than the thorax, narrowed in front, blackish-blue, 
moderately coarsely and moderately closely punctured, 
clothed with a fine pubescence. Thorax not quite so long 
as broad, a little narrowed towards the front, the sides 
straight, the base and hind angles rounded, above of an 
obscure-bluish colour like the head, neither very closely 
nor coarsely punctured, with a short smooth line in front 
of the scutellum, and clothed with a dark fuscous pubes- 
cence. Elytra about as long as the thorax, dull bluish- 
black, rendered black and opaque by a fine depressed 
pubescence, under which they are alutaceous but not 
punctured. Scutellum clothed with black pubescence. 
Hind body narrowed towards the extremity, quite dull 
and densely clothed with a very fine concolorous pubes- 
cence, black, with the 6th and 7th segments yellow. Legs 
black, tibize strongly spinulose.

length or breadth. Mandibles pitchy red; palpi yellow. 
Head a good deal narrower than the thorax, subtriangular, 
the punctures only moderately coarse, those on the an- 
terior part not dense ; it is of a black colour, with a pale 
blue reflection and very slightly shining. Thorax just as 
long as broad, nearly as broad as the elytra, slightly nar- 
rowed in front, covered with a rather coarse but not deep

punctuation, which is close, but the interstices are quite 
distinct and not at all rugose; its depressed pubescence ts 
of a dark colour, but oe altogether black; in colour it is 
similar to the head. ‘The elytra are just as long as the 
thorax, and are covered with a blackish tomentum, which 
makes them appear quite dull and without sculpture, and 
they bear besides a rather close depressed pubescence. 
Hind body black, with the two apical segments bright 
yellow, but the base of the 6th black; the black part is 
covered with a dense dark tomentum, which is quite uni- 
colorous; the anal styles are yellow. The legs are short 
and stout, black. The under face of the hind body is 
distinctly punctured, and bears a rather scanty yellow 
pubescence ; it has a slight metallic reflection. 

Ega; seven indiv iduals. 

Obs.—I at first considered this species a variety of 
S. subcyaneus, but, after examination of a series of seven 
individuals, I consider it likely to prove a distinct species; 
it is considerably smaller, rather darker in colour, has the 
head smaller, and the basal portion of the 6th segment of 
the hind body black. The male characters appear very 
similar. 


3. Staphylinus ochropygus, Nord. var. 


Tapajos, Ega, St. Paulo. 

I identify this species from the descriptions of Nord- 
mann and Eriehson; the specimens agree therewith except 
that they have the legs and antenne paler in colour, 


4. Staphylinus gratiosus,n. sp. Fulvus, capite thorace-

A very pretty species, and remarkable for the peculiar 
sculpture of the head and thorax, the interstices of the 
coarse punctures thereon being finely punctured. An- 
tenn stout, about as long as head and one-third of thorax; 
the two basal joints dark yellowish, the others infuscate ; 
2nd and 3rd joints rather long, the 3rd longer than 2nd, 
5—10 transverse ; last joint truncate at the extremity ond 
pointed on one side. Palpi yellowish; mandibles pitchy. 
Head narrowed in front, narrower than the thorax, shining

greenish, rather coarsely and sparingly punctured, with 
numerous fine punctures mixed with the large ones. 
Thorax nearly as long as broad, a little narrower than the 
elytra, distinctly narrowed in front, of a shining bluish 
colour, but dulled by a dark-fulvous pubescence which 
appears black in most lights; it is moderately coarsely and 
not densely punctured, fine punctures are distributed over 
the interstices of the larger ones. Scutellum densely 
clothed with black tomentum. Elytra about as long as 
the thorax, of a rich tawny colour, quite dull from a , de- 
pressed tomentum, and furnished besides this with rather 
stiff depressed concolorous hairs. Hind body narrowed 
to the extremity, of a tawny-brownish colour, the segments 
furnished on the upper side with a rather scanty golden 
tomentum, and with rather numerous, stiff, concolorous 
hairs. Legs tawny yellow; front coxe a little infuscate. 
The under surface tawny, with a scanty golden pubes- 
cence.

Allied to the preceding but very distinct. Antenne 
longer than the head, the three basal joints tawny yellow, 
the rest infuscated ; joints 2 and 3 rather short, 3rd longer 
than 2nd, 4—10 transverse, but the 4th narrower than the 
5th; 11th joint sinuate at the extremity, one angle being 
pointed. Palpi yellowish. Head small, narrower than 
the thorax, much narrower than the elytra, narrowed. 
in front, rather coarsely but not densely punctured, 
with a considerable impunctate space in the middle, 
shining blue, with a dark-reddish pubescence of erect 
hairs. Thorax about as long as broad, the sides a little 
arched and slightly narrowed in front, coarsely but by no 
means densely punctured, with a very narrow smooth line 
along the middle, shining blue, with a long, erect, reddish 
pubescence. Scutellum with a dense fulvous pubescence. 
Elytra scarcely so long as the thorax, dark tawny, clothed 
with a dense concolorous pubescence, and also with de- 
pressed fine hairs. Hind body narrowed to the extremity, 
reddish-brown; the 5th segment darker at the base, the

6th nearly black, but its hind margin and the 7th segment 

yellowish; it is above clothed with a nearly concolorous

Antenne short and slender, rather longer than the 
head, black, with the extremity of the last joint rusty; 3rd

joints 6—10 much narrowed to the base, but none of them 
transverse (in the ¢ at any rate). Mandibles black ; 
palpi pitechy. Head smaller than the thorax, gre atly 
narrower than the elytra, narrowed to the front, dull 
black, densely and moderately coarsely, but not deeply 
punctured, covered with a dense, fine and short, erect, 
black pubescence. Thorax narrower than the elytra, fully 
as long as broad, the sides nearly straight, not narrowed in 
front, but with the front angles deflexed and rounded; it is 
of a very dull black, densely and rather coarsely but very 
shallowly punctured, densely clothed with a pubescence 
similar to that of the head. Scutellum with a dense black 

velvety pubescence. Klytra slightly longer than the thorax, 
quite dull black, scarcely punctured but rugulose, covered 
with a concolorous pubescence. Hind body black; the sides 
of each segment with coarse shallow punctures; at the base 
of each segment is a middle spot of scanty yellowish or 
ashy hairs, on each side of which there is a velvety-black 
pubescence. The legs are black; the tibiae and tarsi with 
rusty hairs. The wings dull yellowish.

This appears to be one of the most widely distributed 


Staphylinide of the Amazon Valley. 155 


of the South American species of Staphylinus. I have 
specimens which I consider conspecific with Amazonian 
ones, from Nicaragua, Columbia and Rio de Janeiro, as 
well as from intermediate localities.

Closely allied to S. antiquus, Nord.; the thorax not 
longer than broad, not at all narrowed in front, the pubes- 
cence of the hind body darker, &c. It resembles Ocypus 
cupreus, but is a little broader and less elongate. Antennze 
reaching half-way back the thorax; first three joints reddish, 
the rest nearly black; 2nd and 3rd moderately long, 3rd 
longer than 2nd; 4th joint narrower than the 5th, shghtly 
transverse, 5—10 rather strongly so, 11th sinuate at the 
extremity and pointed on one side. Mandibles pitchy; palpi 
reddish. Head rather narrower than the thorax (smaller 
and more triangular in the ¢ than in the 3), coarsely but 
not densely punctured, brassy, the interstices shining; a 
very small, narrow space in the middle free ; clothed with 
a fuscous pubescence. Thorax but little narrower than 
the elytra, almost straight at the side, about as broad in 
front as behind, scarcely so long as broad; coarsely and 
closely punctured, with a line in front of the scutellum 
smooth, and with slight traces of the continuation of this 
in front; furnished with a dense and fine fuscous pubes- 
cence. Scutellum velvety black. Elytra about as long 
as the thorax, not so long as their breadth taken together, 
dull brassy; finely pubescent, and very indistinctly tes- 
sellated. Hind body narrowed at the extremity, pitchy in 
colour, the 7th segment yellowish; each segment has in 
the middle, at the base, an indistinct ashy mark, on each 
side of which the pubescence is more closely placed, so as 
to appear darker; besides this tomentum tkey are clothed 
also with numerous coarse hairs of a dark fuscous, nearly 
black colour. Legs pitchy red. 

Kga; five specimens (¢ and 2). 

Obs.—Besides the above-mentioned five individuals, 
four others from the same locality represent, I believe, a 
variety; they are rather smaller, and have the head a little 
smaller, and the sete of the hind body reddish. In another 


156 Mr. D. Slits Contributions to the 


individual from Para the head and thorax are rather more 
sparingly and a little more coarsely punctured.

Closely allied to the preceding; the head and thorax 
more densely punctured; the thorax both longer and 
broader, and the 3rd joint of the antennz longer. An- 
tenn reaching nearly half-way down the thorax, pitchy ; 
2nd and 3rd joints rather long, 3rd considerably longer 
than 2nd; joints 4—10 differing but little from one another, 
transverse, but not strongly so; 4th joint sinuate at the 
extremity, and pointed on one side. Head small, narrower 
than the thorax, narrowed in front, dull brassy, closely 
and rather coarsely punctured, with a fuscous pubescence. 
Thorax scarcely narrower than the elytra, about as long 
as broad, very slightly narrowed in front, dull brassy, 
coarsely and very densely punctured, with a very short 
and very narrow smooth line in front of the scutellum, and 
clothed with a fuscous pubescence. Scutellum velvety 
black. Elytra about as long as the thorax, dull brassy, 
finely pubescent and indistinctly t tessellated. Hind body 
narrowed to the extremity, pitchy ; 7th segment and hind 
margin of the 6th yellow, obscurely tessellated, with a dark 
brown and scanty ashy pubescence, and besides this with 
coarse, nearly black hairs. Legs pitchy ; femora marked 
with yellow towards the ‘extremity. 

Tunantins; one specimen; also four other individuals 
without special locality. 

Obs.—This species is closely allied to S. antiquus, but 
is larger and broader; the legs, the antenne and the 
pubescence are darker in colour; the antenne are thicker, 
and the carina-like space along the head and thorax is 
absent. 


BELONUCHUs. 


About thirty species are at present referred to this 
genus, and all of them are indigenous to its warmer parts, 
one or two extending their range to the United States of 


Staphylinide of the Amazon Valley. 157 


North America. I here enumerate twelve species from 
the Amazons, of which nine are new. 

The genus has no sufficient characters pointed out to 
distinguish it from the great genus Philonthus ; Erichson 
was in doubt as to whether he should accept it as distinct 
therefrom, and indicated, as the only character peculiar 
to it, the arming of the front and hind femora with seta- 
like spines. This character, however, differs in certain 
species in the two sexes, as will be seen from my descrip- 
tions of B. decipiens and B. setiger. Species possessing 
this character are moreover by no means confined to the 
New World, for I have several undescribed Philonthus- 
like species displaying it from Papua and the Malay 
Archipelago. I have, therefore, only used this generic 
name as a matter of convenience, to avoid increasing the 
enormous number of species already registered under the 
generic name of Philonthus.

PHILONTHUS. 


This generic name at present designates nearly four 
hundred species found in all parts of the world. I here 
describe nineteen new Amazonian species. These nineteen 
species belong to several very different groups. P. amazo- 
nicus is allied to our European P. scybalarius; P. coralli- 
pennis to the group comprising the P. fulvipes and its 
allies; while P. deletus seems quite allied to our P. pro- 
lixus, and, like it, has the appearance of a small Lathro- 
bium. The other species are very different from any we 
have in Europe. P. muticus is very like the depressed 
Belonuchi, and P. gracillimus is very remarkable by its 
elongate, narrow prothorax. The next seven species 
belong to a brightly-coloured group of species which is 
peculiar to South America, and of these seven P. palpalis 
is remarkable by the dilated terminal joint of the labial 
palpi. The next five species belong also to a group con- 
fined to South America: the species in colour much 
resemble those of the preceding group, but whereas in the 
first of the two groups the anterior angles of the thorax 
are distinct and rather prominent, in the second they are 
rounded and very depressed. The P. longipes is in form 
similar to the species I have last named, but it has a very 
peculiar punctuation along the margins of the thorax, and 
its elytra are densely punctured. LP. serraticornis is a re- 
markably aberrant species, which both in appearance and 
structure approaches the insects I describe in this paper 
under the generic name Gastrisus.

segment also rusty; it is rather closely punctured on the 
upper side, the punctuation being denser on the basal 
halves of the 5th and 6th segments than elsewhere; its 
pubescence is rough and coarse. ‘The legs are of a dirty-

Allied to P. salinus, but much narrower, and with the 
prothoracic series of punctures more numerous. The an- 
tennze are long and slender, the basal joint entirely and

at the back and between the eyes it is finely, rather closely 
punctured, the middle part impunctate. The thorax is 
longer than broad, nearly straight at the sides, and not (or 
scarcely ) narrowed in front; it has on each side the middle 
a dorsal row of eight punctures, not very regularly placed, 
and has besides four or five others in a line outside these. 
The scutellum is smoky, densely punctured. The elytra 
are about as long as the thorax, but a little broader, 
of a red colour, very densely and finely punctured, quite 
dull. Hind body rather long and slender, but little nar- 
rowed behind, very densely and finely punctured, the

This species resembles greatly Belonuchus equalis, but has 
the anterior and posterior femora entirely without spines, ex- 
cept the three or four at the extremity of the front femora 
found in most species of Philonthus. The antenne are 
inserted quite at the anterior margin of the front, which is 
not at all produced in the middle; they are a little shorter 
than the head and thorax, the three basal joints reddish, 
the rest infuscated ; the 3rd joint longer than the 2nd, the 
10th about as long as broad. The mandibles and palpi 
are reddish. The head is blackish, with two points on 
each side near the front, at the inner side of the eyes, and 
between these with a punctiform longitudinal impression, 
and with several other punctures on each side, near the

2nd; all the rest of the joints much longer than broad, the 
last paler than the rest. The mandibles and palpi are 
yellowish. ‘The head is narrow, but rather broader than 
the thorax; it is narrowed behind the eyes; it is of a 
black colour, rather finely and closely punctured, with the 
dise impunctate. The thorax is very peculiar in form; it 
is much narrower than the elytra, and very elongate, being 
more than twice as long as broad; it is not narrowed 
behind, but appears somewhat narrowed in front, owing to 
the front angles being greatly inflexed; it is strongly 
sinuate at the sides before the hind angles ; it is of a 
reddish colour, and has on each side the 1 middle a dorsal 
row of five fine punctures, and has also a few other fine 
“punctures on each side. The scutellum is finely punc- 
tured. The elytra are not so long as the thorax, rather 
finely and closely punctured. The hind body is elongate 
and slender, yellowish, with the 5th and 6th segments 
broadly infuscated ; it is closely, finely and evenly. punc- 
tured. The legs are yellow, long and slender.

Antenne nearly as long as the head and thorax, yellow- 
ish; 2nd and 3rd joints about equal, 4—10 each a little 
shorter than its predecessor, none of them transverse. 
Mandibles and palpi yellowish. Head on the upper side 
shining brassy, the front with a medial longitudinal im- 
pression, on which are placed two large confluent punc- 
tures, and on each side of this with three punctures, form- 
ing an irregular row between the eyes, and with eight or 
ten other large punctures on each side at the back part. 
Thorax rather longer than broad, slightly narrowed behind, 
the sides a little sinuate; it is of a shining reddish-yellow 
colour, with a dorsal row of five coarse punctures on each 
side the middle, and with six or seven other large punc- 
tures on each side, near the front. Scutellum pitchy, the 
basal part rather coarsely punctured, the apex impunctate. 
The broad elytra are about as long as the thorax, of a 
shining-yellowish colour, coarsely and sparingly punc- 
tured. The hind body is but little narrowed to the extre- 
mity ; it is of a brownish-yellow colour, with the 5th and 
6th segments black, the extremity of the latter and the 
7th segment pale yellow, the hind portion of the anal styles 
brownish ; segments 2—4 are sparingly and finely punc- 
tured, 5 and 6 much more closely punctured, these latter 
with a coarse, depressed, black pubescence. The legs are 
yellow, the intermediate coxee distant. 

In the male the hind portion of the ventral plate of the 
7th segment is produced in the middle ; the produced part 
is truncate at the extremity, and a little transversely im- 
pressed before this; in front of this depression are inserted 
six or eight fine depressed sete. 

In the female the head is only as broad as the thorax, 
and the front femora are unarmed.

This species is in appearance exactly like the preceding 
one, but differs by the abdominal characters of the male, 
and also by these one or two points, which may perhaps 
be individual rather than specific. The antennz have the 
third joint a little longer, so that it is slightly longer than 
the 2nd, and joints 4—11 are a little more dusky. The 
elytra are rather more closely and finely punctured. 

In the male the middle part of the ventral plate is a 
little produced backwards and has at its extremity a narrow 
but rather deep triangular notch. The head is broader 
than the thorax. 

In the female the head is only as broad as the thorax, 
and the front femora are unarmed. 

Ega; two specimens, ¢, 2. 

Obs.— Besides the specimens above described, there are 
four others from Ega and Tapajos (one ¢ and three ¢?), 
about which I cannot feel sure whether they belong to 
P. cognatus or an extremely closely allied but distinct 
species.

Antenne moderately long, with the three basal joints 
yellow, the rest black; they are slightly thickened towards 
the extremity; the 4th joint is a little longer than broad, 
the 10th hardly so long as broad. Mandibles and palpi 
yellow. Head brassy, rather broader than the thorax, 
with a deep impression on the middle in front, and two 
punctures on each side between the eyes, with a few other 
punctures behind these, and some at the vertex on each 
side ; the middle part smooth and shining. ‘Thorax yellow, 
a good deal narrower than the elytra, longer than broad, a 
little narrowed behind, with a series of five coarse punc- 
tures on each side the middle, and outside this on each side 
with about six other coarse punctures. Scutellum rather 
large, concolorous with elytra, distinctly punctured. Elytra 
of a tawny-yellow colour, scarcely longer than the thorax, 
rather deeply and distinctly but not coarsely nor closely 
punctured, shining, very finely and scantily pubescent. 
Hind body yellow, with the 5th segment black, except at 
the extreme base; the 6th black, with the extremity yellow,

the 7th yellow; the basal segments are very sparingly 
punctured; the 5th and 6th segments are more closely 
punctured, and bear a coarse black pubescence. The legs 
are yellow. The underside of the head is without punc- 
tures. 

In the male the front femora are almost without spines ; 
the ventral plate of the 7th segment has its hind part 
slightly produced in the middle; the produced part is 
nearly entire, there being only an extremely slight emar- 
gination of its hind margin.

mandibles yellowish. Head broader than the thorax, the 
front distinctly produced between the insertion of the 
antennz and with a deep longitudinal impression in front, 
with two large punctures on each side between the eyes, 
and with several other large punctures on each side at the 
back; it is of a shining-brassy colour. Thorax much nar- 
rower than the elytra, rather longer than broad, distinctly 
narrowed behind, the sides a little sinuate; it is similar in 
colour to the head, and has on each side the middle a 
row of five punctures, and also on each side near the front 
six or seven other punctures; all these punctures very 
large. Scutellum nearly black, densely and finely punc- 
tured. lytra about as long as the thorax, reddish, 
broadly black towards the extremity, finely and rather 
closely punctured. The hind body is of a brownish colour 
at the base, then with the 4th, 5th and 6th segments 
black, the hind margin of the latter and the 7th yellow; it 
is on the upper side rather closely punctured, especially on 
the 4th, 5th and 6th segments, where also there is a coarse, 
depressed, dense, black pubescence. The legs are yellowish, 
with the anterior and middle cox infuscated. The 
breast pitchy, the intermediate coxe distant.

Ega; one specimen. This I believe to be a male on 
account of its large head ; the front femora have a few very 
short spines, but the 7th segment of the hind body is 
rounded at the extremity, so that the individual may 
possibly be a fernale.

that the remarkable form of the last joint of the labial 
palpi may be peculiar to the male.

anal styles, is fuscous. The legs are yellow, long and 
slender; the intermediate coxee distant.

This species is extremely close to the preceding one, 
and differs from it only as follows. The thorax is nar- 
rower, the elytra are a little brassy towards the extremity, 
the hind body is more sparingly punctured, the extreme 
base of each of the 5th and 6th segments being much more 
sparingly punctured than in P. aberrans ; the punctures 
on the thorax are larger, and the elytra are rather more 
sparingly punctured. 

Ega; one specimen, &. 

Obs.—I have also another female, found by Mr. Bates, 
which I believe belongs to a closely allied but distinct

rower than the elytra, considerably longer than broad, 
and considerably narrowed behind, the sides sinuate, front 
angles seen from above not much rounded; it is of a red- 
dish-yellow colour, very shining, and has on each side the 
middle a dorsal row of seven very coarse punctures, and 
between these, near the base on each side, three or four 
accessory punctures, so placed as to render the dorsal row 
confused, also with five or six other coarse punctures on 
each side, near the front angles. Scutellum densely and

This is another aberrant species which will probably 
ultimately be separated generically from Philontius, the 
antennze being distinctly serrate and the lateral lines of 
the under surface of the prothorax not joined till quite at 
the front part of the coxal cavities. It is broad and rather 
depressed. ‘The antenne are rather shorter than head

This peculiar genus at present consists of half a dozen 
species, to which I now add five new ones. All the 
species known are South American. The genus was 
placed by Erichson in the Xantholinini, but is assigned 
by Kraatz to the Staphylininit. I have not made a suffi- 
cient investigation to enable me to pronounce an opinion 
as to its nearest allies, but it appears to me to be as yet 
a remarkably isolated form. JZ. discedens here described 
differs from the other species in the structure of its hind 
body, which is more convex, so as to be subcylindric. 


1. Holisus depressus,n. sp. Niger, nitidus, depressus, 
ano rufo, pedibus piceis; capite thoraceque parce fortiter 
punctatis; elytris crebre sat subtiliter punctatis. Long. 
corp. 3? lin. 

Antenne nearly black ; 3rd joint a good deal longer 
than 2nd, 4th and 5th each about as long as broad, 6—10 
very similar to one another, each a little transverse, 11th 
pale at the extremity. Palpi reddish. Head large, 
rather broader than the thorax, oblong, quite straight : at 
the sides, on the front part with coarse punctures, forming 
on each side an irregular patch placed in a slight depres- 
sion; also on each side of the middle with a patch of about 


eleven coarse punctures, also punctured at the sides and at 


Stuphylinide of the Amazon Valley. 181 


the vertex; it is black and shining. Thorax about as 
broad as the elytra, rather broader than long, a little 
sinuate at the sides, and a good deal narrowed behind, 
black and shining, and with a slight opalescent reflection, 
bearing a few irregularly-placed, rather coarse punctures. 
Scutellum rather large, coarsely punctured. Elytra pitchy 
black, much longer than the thorax, rather coarsely and 
closely but yet not densely punctured, distinctly shming. 
Hind body rather broad and depressed, coarsely and rather 
closely punctured, the 6th segment more sparingly so, 
and the yellowish 7th segment. still more sparingly. 
Legs short and stout, pitchy. 

Kga; a single individual. 

Obs. I—A_ second individual, brought by Mr. Bates 
from the same locality, may be either the other sex of 
HT, depressus or a closely allied but distinct species; it 1s 
a little smaller, and has the head rather shorter and the 
hind body not quite so closely punctured; it has the hind 
margin of the ventral plate of the 7th segment of the hind 
body rounded, while this part is more truncate in HZ. de- 
pressus. 

Obs. 1I.—H. depressus is very closely allied to H. analis, 
Er., but is rather larger and broader, has the thorax shorter 
in proportion to its length, and the elytra less densely and 
rather more coarsely punctured. 


2. Holisus picipes, n. sp. Parallelus, minus latus, 
nitidus, niger, pedibus piceis; capite thoraceque vage, 
elytris subtiliter minus crebre, abdomine fortiter, punc- 
tatis. Long. corp. vix 3 lin.; lat. 3 lin. 


Allied (judging from description) to H. humilis, Er., 
but larger, and with the elytra more finely punctured. 
Antenne rather longer than the head, not stout; 3rd joint 
distinctly longer than 2nd; 5th joint about as long as 
broad, 6—10 each a little transverse. Mandibles pitchy ; 
palpi dusky yellowish. Head oblong, straight at the 
sides, the hind angles not much rounded, the length from 
clypeus to vertex a little greater than the width; it is 
black and shining, rather strongly and coarsely punctured, 
the punctures being disposed as follows: a patch of about 
seven on each side placed in an obscure depression behind 
the antennz, and between these two patches two or three 
other punctures; behind these a broad, longitudinal space 
is impunctate, and at each side behind is a large patch of 


182 Mr. D. Shas Contributions to the 


fifteen or sixteen punctures, each patch consisting of three 
indistinct oblique rows. Thorax just about as broad as 
the head and elytra, its width distinctly greater than its 
length; it is a little narrowed behind, and has on each 
side sixteen or eighteen punctures irregularly scattered ; 
the middle space between these punctures much narrower 
at the back part than in front. Elytra longer than the 
thorax, pitchy black, finely and not closely punctured. 
Hind body parallel, rather coarsely but not densely punc- 
tured. Legs pitchy. 
Ega; two specimens. 


3. Holisus excavatus, n. sp. Piceo-testaceus, nitidus, 
antennis pedibusque testaceis, thorace concavo, elytris 
dense subtiliter punctulatis. Long. corp. 1? lin. 


Antenne considerably longer than the head, yellow ; 
3rd joint scarcely longer than 2nd, 6—10 a little trans- 
verse. Mandibles and palpi yellow. Head pitchy, broad, 
even a little broader than thorax or elytra; the length 
about as great as the width; the hind angles considerably 
rounded; the upper surface sparingly and irregularly 
punctured, the punctures leaving scarcely any distinct 
smooth space in the middle. Thorax as broad as the 
elytra, about as long as broad, narrowed behind, the sides 
rounded; it is of a pitchy-yellow colour; the whole of the 
upper surface concave, sparingly and irregularly punc- 
tured. The elytra are longer than the thorax, finely and 
closely punctured, of a pitchy-yellow colour, their disc 
concave. Hind body pitchy yellow, rather finely, mode- 
rately closely punctured. Legs yellow. 

Ega; one specimen. 

Obs.—This individual is a little immature, so that the 
colour of the species may be somewhat darker than is here 
described, and it is probable that when fully developed 
the elytra may be without impression, but I expect the 
thorax is naturally concave on the upper surface. 


4, Holisus umbra, n. sp. Omnium perdepressus, an- 
gustus, nitidus, piceus, antennarum basi, pedibus, anoque 
testacels; thorace concavo, elytris crebre subtiliter punctu- 
latis. Long corp. 13 lin. 


Antenne rather slender, a little longer than the head, 
dusky yellow, paler at the base; 3rd joint small, shorter 
than the 2nd, 6—10 rather transverse. Palpi yellow. 


Staphylinide of the Amazon Valley. 183 


Head rather large, fully as broad as thorax or elytra, 
oblong-quadrate, the sides straight, the hind angles a little 
rounded ; it ison the upper side rather finely and sparingly 
punctured. Thorax as long as broad, narrowed behind 
and rounded at the sides, the upper surface deeply 1m- 
pressed, finely and sparingly punctured, an oblong space 
on the disc impunctate. Elytra quite as broad as, and. 
longer than the thorax 5 like it, and the head, of a 
pitchy colour, closely and finely punctured. Hind body 
parallel, pitchy, with the extremity yellow, evenly, mode- 
rately finely, and moderately closely punctured. Legs 
yellow. 
Ega; one specimen. 


5. Holisus discedens, n. sp. Niger, nitidus, pedibus 
piceis ; capite thoraceque parce fortiter punctatis; elytris 
crebre subtiliter punctatis; abdomine minus depresso, sat 
crebre punctato. Long. corp. 23 lin. 


Palpi pitchy ; Ist and 2nd joints of antenn pitchy 
(the rest wanting). Head black, quite depressed, quite 
straight at the sides and vertex, the hind angles rounded ; 
+t is rather broader than the thorax or elytra, and bears 
coarse and distinct but not dense punctures. Thorax 
short, about long as broad, rounded at the sides, and a 
good deal narrowed behind; the front much rounded, so 
that the front angles are quite rounded, with a series of 
punctures on each side of the middle, leaving between 
them a broad, impunctate space, and outside these with 
some punctures, which are most numerous behind the 
nfiddle; it is black and shining, and shows at the base, in 
the middle, a very short and fine channel. Scutellum 
rather coarsely punctured, the punctures disappearing 
towards the apex. Elytra much longer than the thorax, 
of a pitchy-black colour, rather finely and closely punc- 
tured, the punctures rather closer at the extremity than at 
the base. Hind body elongate and narrow, less depressed 
than the front parts ; the dorsal plates are convex, so that 
it is subcylindric, and the lateral margins are extremely 
fine; it is a good deal narrowed towards the extremity, 
and also has the basal segment slightly narrower than the 
following ones; it is quite black in colour, and is rather 
coarsely but not altogether densely punctured. ‘The legs 
are pitchy. 

In the individual described, which I believe to be a 


184 Mr. D. Sha: Contributions to the 


female, the apical segment has a lateral style on each side, 
and two more slender ones between them. 

A single specimen was found by Mr. Bates, but it bears 
no special indication of locality. 


Diocnws. 


This genus consists of seven described species, found in 
widely separated parts of the world, and I now add four 
new species from the Amazons; these call for no special 
remark, as they appear to be extremely closely allied to 
one another. 

The genus is one of considerable importance, notwith- 
standing the insignificant and unattractive appearance of 
the species which compose it. Some years ago, I examined 
it, and came to the conclusion that it could not be satis- 
factorily classed with the Xantholinini, with which it is 
usually associated. On glancing at some of its points of 
structure again, I am inclined, however, to suspect that it 
may prove to be one of the earliest and least specialized 
forms of the Xantholinini, and that a careful study of its 
peculiarities may throw considerable light on the nature 
of the modifications distinctive of that group, as well as 
suggest the species of the Staphylinini, with which the 
Xantholinini are most directly connected. 


1. Diochus longicornis, n. sp. Obscure rufo-testaceus, 
nitidus, capite elytrisque cirea scutellum  infuscatis. 
Long. corp. 2 lin. . 


At once distinguished from D. flavicans by the much 
longer antennz. These are slender and reach not quite 
to the extremity of the thorax; they are of a yellow 
colour; 3rd joint is long and slender, longer than the 2nd ; 
from 4—10 each is a little shorter than its predecessor, 
even the 10th considerably longer than broad. Head 
pitchy-red, slightly narrower than the thorax, very little 
narrowed in front, the front part indistinctly punctured, 
the punctures placed in irregular lines. Thorax a little 
narrower than the elytra, longer than broad, very slightly 
narrowed in front, dusky reddish-yellow, with four punc- 
tures near one another on the middle, behind; in front of 
these with two others farther apart, and with four or five 
others on each side. Elytra hardly so long as the thorax, 
yellow, darker about the scutellum, sparmgly and very 


Staphylinide of the Amazon Valley. 185 


indistinctly punctured. Hind body dusky yellow, ex- 
tremely finely and densely punctured. Legs yellow. 
Tapajos ; seven specimens. 


2. Diochus vicinus, n. sp. Rufescens, capite elytris- 
que infuscatis, his apice dilutioribus; antennis tenuibus, 
sat elongatis. Long. corp. 2 lin. 


Antenne reddish, not thickened towards the extremity, 
moderately long; 3rd joint elongate and slender ; 4—10 
each is a little shorter, but scarcely visibly broader, than 
its predecessor, the 10th quite as long as broad; 11th 
joint much acuminate. Head _ small, infuscate-red. 
Thorax bright reddish-yellow. Elytra about as long as 
the thorax, infuscate-red, with the hind margin paler, 
shining, with a few indistinct punctures. Hind body 
dark red, densely and finely punctured. Legs yellow. 

Tapajos; three specimens. 

Obs.—This species is extremely similar to D. longi- 
cornis, but the antennz are less elongate. 


3. Diochus tarsalis, n. sp. Rufo-fuscus, antennis pedi- 
busque testaceis, illis sat elongatis; tarsis anterioribus 
dilatatis. Long. corp. 2 lin. 


Antenne moderately slender, reddish ; 3rd joint slender 
and elongate; 4—10 each a little shorter, but scarcely 
visibly broader, than its predecessor; 10th about as long 
as broad, 11th much acuminate. Palpi yellow. Head 
infuscate-red, impunctate along the middle, with a few 
punctures at the sides. Thorax infuscate-red, rather 
brighter in colour than the head, with the usual pune- 
tuation. Elytra about as long as the thorax, infuscate- 
red, shining, with a few impressed punctures. Hind body 
densely punctured, blackish-red, with the hind margins of 
the segments red, the hind part of the two slender and 
* elongate apical segments broadly red. Legs yellow, front 
tarsi rather strongly dilated. 

Tapajos; three specimens. 

Obs.—This species is extremely similar to D. long?- 
cornis and D. vicinus, but is rather darker in its coloura- 
tion, and has the front tarsi a good deal dilated, while in 
the two species named they are nearly simple. 


4, Diochus flavicans, n. sp. Rufo-testacens, nitidus, 


” 


186 Mr. D. Shas Contributions to the 


antennis articulis 3—10, elytrisque basi infuscatis. Long. 
corp. 14 lin. 

Antenne considerably longer than the head, the two 
basal joints and the last joint yellow, the others infuscate; 
3rd joint about as long as 2nd, 6—10 rather transverse. 
Head narrower than the thorax; narrowed in front, reddish- 
yellow, convex, the front part sparingly and indistinctly 
punctured, the vertex smooth. Thorax a little narrower 
than the elytra, considerably longer than broad, distinctly 
narrowed in front, the sides slightly curved; it is reddish- 
yellow, and has four punctures placed near one another 
on the middle, behind; in front of these, two others much 
farther apart, and on each side five or six other punctures 
near the lateral margin. LElytra scarcely so long as the 
thorax, yellowish, indistinctly darker near the base, 
sparingly and indistinctly punctured, the punctures dis- 
posed in lines. Hind body dusky yellowish, very finely 
and densely punctured. Legs pale yellow. Front tarsi 
not dilated. 

Tapajos; two specimens. 


STERCULIA. 


This genus consists at present of six species, all peculiar 
to South America, and I here describe seven new ones. 
The genus contains two apparently distinct groups: the 
first of these consists of lar ge and brilliant species, which 
are amongst the most splendid of the Staphylinide; the 
species, however, bear such an extreme resemblance to one 
another, that, although I have twenty different forms be- 
longing to it separated in my collection, I am by no means 
sure how many species they represent: the second group 
consists of black and rather smaller species, which have the 
mandibles much less elongate than the metallic species. 
S. amazonica, S. pauloensis and S. discolor belong to 
the group of metallic species, while the other four here 
described are black species with short mandibles. 


1. Sterculia amazonica, n. sp. Cyanea, nitida, thorace 
elytris breviore, capite oblongo, subtus lateribus parce 
punctato, medio levi, mandibulis capite brevioribus. 
Long. corp. 10 lin.; lat. ely trorum apice 2} lin.; prothoracis 
basi Ad lin, : 


Antenne rather stout, not thickened after the 4th joint ; 
3rd joint about twice as long as 2nd, 4—10 transverse ; 


Staphylinide of the Amazon Valley. 187 


the three basal joints blue, the rest obscure. Palpi stout. 
Mandibles about two-thirds of the length of the head. 
Head quite as broad as the greatest w idth of the thorax, 
its width about as great as from the front of the eyes to 
the back of the head; the whole of the upper surface 
densely, evenly and coarsely rugose-punctate, beneath 
very shining, the punctures there about tw enty-four on 
each side; those at the back angles small, the others very 
large, the middle part quite free. Thorax considerably 
longer than broad, a little narrowed from the base to the 
middle, more narrowed from the middle to the front; a 
deep oblique impression on each side, near the back; the 
sides in front of the impression rather sparingly punctured, 
a broad middle line impunctate. LElytra longer than the 
thorax, finely and sparingly punctured. Hind body very 
shining, very finely and very sparingly punctured. Legs 
violet. Hind body beneath less sparingly and finely 
punctured than above. 

ga; six individuals. 

Obs.—These specimens vary somewhat in their colour, 
which is sometimes purple, sometimes of a bluer or greener 
tint; the punctures also on the underside of the head are 
more numerous and distinct in some individuals than in 
others. Two specimens have the 7th segment beneath 
a little depressed in front of the hind margin, and more 
finely punctured and pubescent, the hind margin itself 
being very slightly emarginate; I think they are pro- 
bably males. 


. Sterculia pauloensis, n. sp. Cyanea, nitida, thorace 
i ee breviore, capite oblongo, subtus basin versus parcius 
punctato, mandibulis capite brevioribus. Long. corp. 
12 lin.; lat. elytrorum apice 2% lin.; prothoracis basi 
14 lin. 

Very closely allied to the preceding species, but larger, 
and with the mandibles a little longer, the head and tho- 
rax broader, the head being distinctly broader than the 
thorax, while the thorax is less slender in front; the 
punctures on the under side of the head are only eleven 
im number, smaller punctures near the hind angles being 
quite absent. 

St. Paulo; a single individual. 

Obs.—It is quite possible this may not prove to be a 
distinct species from the S. amazonica, which, as I have 
above noticed, appears to be somewhat variable. 


188 Mr. D. Shaggts Contributions to the 


3. Sterculia discolor, n. sp. Supra violacea, abdomine 
aureo-purpureo, subtus viridi-cerulea, nitida, capite ob- 
longo, mandibulis hoc brevioribus, thorace elytris vix 
breviore. Long. corp. 9—11 lin. 


Readily distinguished from S. amazonica by the dis- 
cordant colour of the hind body above, as well as by the 
much less transverse penultimate joint of the antenne. 
Antenne rather long, reaching more than half-way to the 
back of the thorax, not thickened after the 4th joint; the 
three basal joints violet, the others dusky; from 6—10 

each joint is a little longer than the preceding one, so 

that the 10th is considerably longer than the 6th. Man- 
dibles much shorter than the head. Head rather narrow, 
considerably longer than broad, slightly broader than the 
thorax; the eyes distinctly prominent; it is of a violet 
colour above, densely and coarsely rugose-punctate ; 
beneath it is shining blue, sparingly punctured on each 
side with about fourteen punctures. Thorax one and a 
half times as long as broad, gradually narrowed from the 
base to the front, with an oblique impression on each side 
before the base, a space along the middle smooth; the 
sides rather sparingly punctured, more closely at the 
front than elsewhere. Elytra much broader and slightly 
longer than the thorax, of a dark-violet colour, finely and 
moderately closely punctured. Hind body above of a 
brilliant golden purple, or copper colour, sparingly and 
finely punctured, beneath brilliant green. Legs violet; 
pubescence of the tibize conspicuous, ‘being nearly white. 

In the male the hind margin of the 7th segment beneath 
is less rounded than in the female, and the punctuation in 
front of this is a little denser and finer. 

Ega; six specimens. 

Obs.—This species is very closely allied to the Bolivian 
S. splendens, but is rather more slender, and has the 
mandibles shorter; the antenne are considerably shorter, 
and the sculpture of the head at the vertex is less dense 
and rugose. 


4. Sterculia funebris, n. sp. Nigro-subenea, opaca, 
densius subtiliusque punctata, thorace linea media levi, 
elytris thorace brevioribus. Long. corp. 9 lin. 


Antenne black, rather stout, reaching about half-way 
to the back of the thorax, a little thickened from the 4th 
to the 10th joint; 3rd joint considerably longer than 2nd, 


Staphylinide of the Amazon Valley. 189 


this latter red at the extreme base; joints 4—10 strongly 
transverse, scarcely differing in length. Mandibles about 
half as long as the head. Head slightly narrower than 
the thorax, considerably longer than broad, oblong, the 
hind angles much rounded, but the sides straight; above 
black, and quite dull, with a very faint brassy tinge, ex- 
tremely densely and finely rugulose-punctate, with a very 
dense, short and fine erect pubescence; lateral grooves 
broad, shallow and densely punctured, these limited on 
the underside by a smooth, rather elevated line, the rest 
of the under surface coarsely and numerously punctured ; 
punctuation at the hinder part fine and dense, passing 
gradually into that of the upper surface. Thorax about 
two-thirds of the width of the elytra; its length quite one 
and a half times its width, slightly broader from the base 
to a little in front of the middle, thence much narrowed 
and rounded to the front, extremely densely and finely 
punctured, with an extremely short and fine, erect pubes- 
cence, quite dull, with a middle line smooth, shining and 
impunctate; it is also slightly transversely impressed some 
distance in front of the base, and in this transverse impres- 
sion the smooth middle line is very nearly interrupted ; it 
is similar in colour to the head. Elytra with their greatest 
length (2. e., measured from the humeral angle to the outer 
apical angle) just equal to that of the thorax, extremely 
densely and finely punctured and pubescent, opaque black. 
Hind body rather shining, brassy black, extremely finely 
and rather closely punctured, and delicately pubescent. 
Legs blackish, the tarsi pitchy; the inside of the tibic 
with a dense-grey pubescence. 

Ega; four specimens; sex unknown. 

Obs.—This species is clearly closely allied to S. formz- 
caria, EXr., but contradicts his description in several im- 
portant points. S. formicaria was originally described by 
Laporte, but his description and figure are quite worthless, 
and it is impossible to decide whether they relate to Erich- 
son’s species or not. richson places as synonyms of 
S. formicaria, the flagellicornis and pubescens of Nord- 
mann ; these two descriptions are very carefully drawn up 
by Nordmann, and it appears to me clear that they refer 
to two distinct species, and are erroneously united by 
Erichson under the name of formicaria. Hence I con- 
sider the name formicaria should be entirely dropped, and 
Nordmann’s jlagellicornis be used instead, leaving it to a 
comparison of the types (in the Museum at Berlin, see. 


190 Mr. D. Shs Contributions to the 


Nordmann) to determine whether my opinion as to pubes- 
cens, Nord., being a distinct species be correct. A 
specimen from Laporte’s collection is in my possession, 
belonging to a-closely allied but distinct species from 
S. funebris, but whether it a the individual from which 
he drew his description of S. formicaria I cannot say, 
though it bore that name in his collection. 


5. Sterculia fimetaria, n. sp.  Nigro-senea, nitida, 
capite oblongo-ovali, opaco; thorace crebre punctato linea 
lata impunctata, elytris hoc brevioribus. Long. corp. 
6—7 lin. 

Antenne stout, much thickened to the extremity, the 
scape pitchy, the flagellum obscure ferruginous ; 3rd joint 
not quite one and a half times so long as the and : 4—10 
transverse, differing but little in length, but the 10th quite 
twice the width of the 4th; 11th joint stout and rather 
short, notched on one side at the extremity. Mandibles 
pitchy, very short; palpi reddish. Head narrow, scarcely 
so broad as the thorax, nearly twice as long as broad, 
coarsely and closely punctured, a little smooth in the 
middle near the front ; beneath it is shining and irregu- 
larly punctured, the punctures there moderately coarse, 
with some coarser ones towards the front in the middle; the 
lateral grooves narrow and punctured, the smooth space 
limiting them beneath broad and distinct. Thorax elon- 
gate, nearly twice as long as broad, about half the width 
of the elytra, the sides nearly straight from the base to in 
front of the middle, then gently narrowed; it is brassy 
black, the middle broadly smooth, very shining and im- 
punctate, the sides evenly, moderately closely, and mode- 

rately coarsely punctured; the pubescence scanty, the 
oblique impressions quite obsolete. Elytra rather shorter 
than the thorax, brassy, rather shining, finely and rather 
closely punctured, with a fine erect pubescence. Hind 
body brassy, finely and closely punctured and pubescent. 
Legs pitchy black ; tarsi paler. 

Tn the male the hind margin of the 7th segment beneath 
is a little emarginate, and just in front of this the segment 
is rather more closely and finely punctured. 

Ega; three individuals, two é, one ?. 

Obs.—One of these specimens is labelled by Mr. Bates 
as found under dung. 


6. Sterculia clavicornis, n. sp. Nigro-eenea, nitida, 


Staphylinide of the Amazon Valley. 191 


capite opaco, crebre subtiliter punctulata, thorace linea 
media lzvi; antennis pedibusque obscure ferrugineis. 
Long. corp. fere 6 lin. 

Allied to S. fimetaria, but very distinct by its smaller and 
shorter head, which is very differently punctured beneath. 
The antenne are stout, much thickened towards the ex- 
tremity, dark reddish, the basal joints pitchy ; 3rd joint 
longer than 2nd; 4—10 very short and broad, not differing 
from one another in length, 10th nearly twice as wide as 
the 4th; 11th jomt short, stout and pointed, not oblique 
at the extremity. Mandibles pitchy, very short; palpi 
yellowish. Head rather longer than broad, nearly straight 
at the sides, but greatly rounded at the back, about as 
broad as the thorax; above quite dull, densely rugulose- 
punctate, the punctuation at the es very fine, the 
pubescence dense and rather long; beneath closely pune- 
tured at the sides, more sparingly and coarsely towards 
the middle, the lateral grooves closely punctured, not deep, 
and not separated from the part beneath by any distinct 
smooth space. Thorax much narrower than the elytra, 
nearly twice as long as broad, slightly broader from the 
base to in front of the middle, then narrowed to the front; 
the sides are rather closely and not very finely punctured, 
with an impunctate space along the middle, the oblique 
impression not well marked, the pubescence rather dense. 
The elytra are rather shorter than the thorax, moderately 
finely and rather closely punctured, with a rather long 
pubescence; like the thorax, of a shining brassy-black 
colour. Hind body closely and finely punctured, with a 
dense soft pubescence. Legs pitchy red ; the tibize on the 
inside with a grey pubescence. 

Obydos; one specimen, probably a female. 


7. Sterculia minor, n. sp. Nigro-enea, nitida, capite 
opaco, thorace elytrisque crebre subtilissime punctulatis, 
illo lineé media levi; capite subtus crebrius punctato, 
sulcis lateralibus nullis. Long. corp. 53 lin. 


Closely allied to S. clavicornis, but with the head and 
thorax rather broader, the punctuation of the thorax and 
elytra much finer, and the head without any lateral 
grooves. The antenne are rather stout, nearly black, the 
extreme base of the 2nd joint red; 3rd joint considerably 
longer than the 2nd; 4—10 each a little stouter than the 
preceding one, transverse, differing but little in length, 


192 Mr. D. Shas Contributions to the 


10th not twice as wide as the 4th; 11th joint rather long, 
pointed and obliquely sinuate at the extremity. Man- 
dibles short, pitchy. Head almost as broad as the thorax, 
oblong, nearly straight at the sides, the hind angles 
rounded, above very “densely rugose-punctate, quite dull, 
brassy black, the pubescence dense, especially at the back; 
beneath it is shining and rather closely punctured, the 
punctures coarser in the middle than at the sides, a narrow 
line in the middle smooth. Thorax considerably narrower 
than the elytra, one and a half times as long as broad, in 
the middle slichtly broader than at the base, then nar- 
rowed to the front, oblique impression rather distinct, a 
space along the middle smooth; the sides closely and very 
finely punctured, the pubescence rather dense. Elytra 
about as long as the thorax, closely and very finely punc- 
tured, brassy black like the thorax. Hind body finely and 
moderately closely punctured, brassy black, pubescent. 
Legs nearly black; tibize on the insides with a grey 
pubescence. 
Fonteboa and Ega; two specimens, probably females. 


AGRODES. 


This genus was established by Nordmann for an elegant 
South American species, but was united with Sterculia 
by Erichson. The genus appears to me, however, to be 
so distinct, that I have used Nordmann’s name as indi- 
cating a separate genus. ‘The differences in the trophi 
from Sterculia (Areocmemis, Nordmann), are accompa- 
nied by a marked distinction in the form of the head, and 
by a greater development of the prosternum in Agrodes, 
and these appear to me sufficiently important and constant 
to justify the acceptation of Nordmann’s two genera. The 
species of Agrodes appear to be excessively rare ; so much 
so, that I have never seen any other specimens of it than 
the two individuals here described as two distinct new 
species.

2nd; 4—10 very similar to one another in length, and 
each scarcely stouter than the preceding; the last joint 
sinuate at the extremity. Mandibles nearly one-half 
as long as the head. Head as broad as the thorax, the 
hind part gradually narrowed into the neck; it is scarcely 
shorter than the thorax, considerably longer than broad ; 
above it is densely and coarsely rugose-punctate, and with 
a rather long pubescence, beneath it is very shining and 
rather sparingly punctured ; the lateral grooves are absent, 
but a raised, smooth space, proceeding from. the base of 
the mandible, indicates what should be the boundary of 
the groove beneath. The thorax is elongate, about twice 
as long as broad, about half as broad as the elytra; it is 
nearly straight at the sides from the base to the middle, 
thence narrowed to the front; it is of a shining-blue 
colour, finely and rather sparingly punctured, with an 
impunctate space along the middle. Elytra scarcely so 
long as the thorax, and darker in colour, rather finely 
and sparingly punctured. Hind body shining blue, finely 
and rather sparingly punctured. Legs bluish, tibiz with 
a grey pubescence on the inside. 
Ega; one specimen, probably female.

Allied to the preceding species, but with the head diffe- 
rently formed, and closely and coarsely punctured beneath. 
The antenne are nearly black, with the three basal joints 
bluish ; the extreme base of the 2nd joint red; they are 
not thickened after the 4th joint, joints 4—10 scarcely 
differing in length and breadth ; last joint sinuate at the 
extremity, ferruginous at the tip. Mandibles not half 
the length of the head. Head long and narrow, with the 
eyes very prominent; it is about as long and about as 
broad as the thorax, the hinder part much narrowed to 
the neck ; it is above densely rugose-punctate, of a violet 
colour, not shining, with a rather dense pubescence ; 
beneath it is very shining, closely and very coarsely punc- 
tured, without any trace of lateral grooves. Thorax 
considerably move than half the width of the elytra, 
nearly twice as long as broad, nearly straight at the sides

Genus Xantholininorum insignis, Scytalino affinis. 


This genus differs from Scytalinus by the presence of 
the upper line of the side piece of the thorax, by the thick 
antenne, which are more approximate at their insertion 
and separated by a compressed carina-like space, as well 
as by its much more robust build. I have a third species 
found by Mr. Belt in Central America, and the nearest 
allies known to me are some undescribed species from 
Natal and Madagascar; in the Natal species the antennz 
are extraordinarily thick, and separated at their insertion 
only by a thin lamina.

behind, considerably longer than broad, black and shining, 
with a very fine and short impressed line in front of the 
scutellum, with a coarse puncture on each side near the 
front angles, and at the front angles with several other - 
finer punctures; also on each side the disc, a little behind 
the middle, is a single puncture, and between this and the 
front are two or three others on each side placed close 
together, and numerous others close to the lateral margin. 
Scutellum with three or four punctures in the middle. 
Elytra about as long as the thorax, black, rather coarsely 
and sparingly punctured, the punctures closer near the 
suture than elsewhere, with a few fine sete. Hind body

linus and Xantholinus: the three species I have placed 
in it will probably be ultimately separated generically ; 
indeed the ZL. tenuipes and extremus appear to be con- 
generic with Thyreocephalus Jekeli, Guér. ; but as Gué- 
rin’s genus is not accepted at present, and as the Linidius 
recticollis does not agree therewith, I have associated all 
the three species under the name Linidius, leaving the 
union of L. tenuipes and L. extremus with T. Jekeli, 
until the genus Thyreocephalus is again rehabilitated. 
The limits of the genera of Xantholinini are, in fact, at 
present about as uncertain as possible.

Mandibles short and stout, black. Head about as broad 
as the thorax, longer than broad, slightly narrowed in 
front, shining black, coarsely and sparingly punctured, the 
punctures wanting on the front part; beneath also sparingly 
and coarsely punctured, the punctures wanting in the 
middle. Thorax narrower than the elytra, straight at the 
sides, nearly twice as long as broad, shining black, and only 
punctured at the sides and front angles. “Seutellum with 
four or five coarse punctures. Jlytra scarcely so long as

This insect so greatly resembles the L. tenuipes, that a 
reiterated description is useless. In ZL. extremus the head 
is broader, more curved at the sides, and so more cir- 
cular in form; the punctures at the side of the head are 
more closely packed, and on each side, just behind and 
internal to the eye, are three larger punctures, placed near 
to one another, so as to form a triangle. The extreme 
vertex, as in L. tenuipes, bears sparing coarse punc- 
tures. The basal portion of the mandibles is more slender 
than in L. tenuzpes, and the legs and tarsi are even a little 
more slender than in that species.

XANTHOLINUS. 


Under this generic name there are at present placed 
something more than one hundred species, found in all 
parts of ‘the world. I enumerate here ten Amazonian 
species, seven of which are new; but I have no doubt the 
species to be found in this rich valley are very much more 
numerous than this. The genus at present contains a 
number of very different forms, some of which have been 
considered by some authors as distinct genera, but have 
not been generally received as such at present. About 
thirty species from South America haye been as yet de- 


Staphylinide of the Amazon Valley. 199 


scribed, and it is in this part of the world that the largest 
and most brilliant of the forms included in the genus are 


found. 


1. Staphylinus rutilus, Perty. 

Para, Ega, Tapajos. 

The fine series brought back by Mr. Bates of this 
species show that it varies much in size, large individuals 
being 9 lin. in length, and the smallest only about 5 lin. ; 
the yellow colour of the extremity of the hind body is in 
the larger individuals nearly entirely absent.

LEPTACINUS. 


This genus at present consists of about twenty-five 
species, distributed over most parts of the globe; only 
two, however, have as yet been indicated from South 
America. As regards the single Amazonian species here 
described, I may remark that it differs much from the 
ordinary form of Leptacinus by its long and slender legs 
and scarcely spinulose tibisw, as well as by the greater 
development of the prosternum; I had at first intended 
giving it a new generic name, but as the limits of the 
neighbouring genera are at present uncertain, and as I 
cannot make a sufficiently complete examination of the 
only individual I possess, I have decided on calling it 
Leptacinus nitidus.

its much shorter maxillary palpi; the single species I refer 
to it differs much in appearance from 1. noth us, on account 
of its shining and sparingly punctured surface. In these

proper to associate it at present in the same genus with 
the eyeless 7. italicus.

METOPONCUS. 


This generic name is applied by Kraatz to designate 
the species formimg Family I, of Erichson’s genus 
Leptacinus. It at present covers only seven species found 
in Eastern Europe, tropical Asia, and South America. 
I refer three Amazonian species to the genus, one of 
which, however, viz. M. holisoides, is very different in its 
appearance from the others, and will almost undoubtedly 
be ultimately considered a distinct genus; but I have not 
been able in my examination of the only individual I have 
seen of the species to detect characters that would justify 
me in making a new generic name at present for it.

OPHITES. 


This genus at present contains three very remarkable 
species, described by Erichson, from South America; it 
appears to me to approach very closely to Cryptobium, 
though Erichson interpolates many genera between the 
two. The single remarkable Amazonian species I here 
describe has the head more abruptly narrowed, to form a 
slender neck, than is the case in the species described by 
Erichson, and its general appearance is rather that of a 
Stilicus than a Cryptobium ; it also has the antenne and 
palpi shorter and stouter than in O. velitaris and Raphi- 
dioides.

This insect has very much the form of an elongate 
Stilicus. It is quite dull above, and everywhere ex- 
tremely densely and finely punctured. The antenne are 
reddish, about as long as head and thorax, very slightly 
thickened towards the extremity, the 1st joint as long as 
the four or five following together; after the Ist, each joint 
is a little shorter than its predecessor, the 10th joint only 
about as long as broad; the last joint small and rounded. 
The head is broader than the thorax, nearly as broad as 
the elytra, the front part much produced; the eyes placed 
about the middle of the sides, the grooves for the antennz 
very distinct. The thorax is only about half as broad as 
the elytra; about twice as long as broad, very slightly 
broader from the base till two-thirds towards the front, 
then narrowed to the apex; it is obscurely elevated in 
the middle at the base, and slightly depressed on each 
side of this elevation; the elytra are about as long as the

I give the above generic name to two new species allied 
to Cryptobium with some reluctance, because that genus 
contains a variety of forms, several of which, in one or 
more respects, approach these insects; the very narrow 
neck by which the head is articulated with the thorax is, 
however, not met with in Cryptobium.

CRYPTOBIUM. 


This genus is known to be much more richly repre- 
sented in species in the New World than it is in the other 
hemisphere; about twenty-two species have been hitherto 
described from the southern half of America, and I here 
add twenty species,—eighteen discovered by Mr. Bates and 
two by Dr. Trail. These tw enty species show a remark- 
able diversity in form. The broad, flat, and ferocious- 
looking Cryptobium gigas offers, indeed, a most striking 
contrast in its appearance to the completely cylindric 
Cryptobium cylindricum. One of the most interesting 
peculiarities of the genus is, that in the males of some of 
the species the ventral plate of the fourth segment of the 
hind body is furnished with projections or appendages of 
size and form differing according to the species. I have 
ascertained that in one of the species here described 
(Cryptobium alternans) this lobe varies in its development 
in different males, in a manner similar to that which 
occurs in the male projections and processes found on the 
more anterior parts of the body in various Coleoptera. 
It appears probable to me that these developments in 
Cryptobium are of a similar character and origin to those 
secondary sexual characters considered by Darwin to play 
an important part as influencing sexual selection; and 
that they exercise little or no influence on the direction of 
the movements of the abdominal segments, as the notches 
and processes so common in Staphylinide on the more apical 
segments appear to me undoubtedly to do.

A very robust species for the genus. Antenne black, 
rusty towards the apex, slender, nearly as long as head 
and thorax; 1st joint as long as the five following, 3rd 
joint longer than 2nd, 4—11 each a little shorter than its 
predecessor, each longer than broad. Head broader than 
the thorax, nearly as broad as the elytra, suborbiculate, 
being about as broad as long, and narrowed and rounded 
behind the eyes, the front part but little produced, elevation 
at base of the antenne very marked; it is black and quite 
dull, obsoletely and sparingly punctured; close to the 
inner margin of the eye is a peculiar ocellated puncture, 
and there is another similar one at the side, some distance 
behind the eye. ‘Thorax not much more than half as 
broad as the elytra, subcylindric, about as long as the 
head, one and a half times as long as broad, dull black, 
like the head, and obsoletely and sparingly punctured, a 
little in front of the base, with a longitudinal smooth 
elevation, and on each side of this slightly depressed. 
Elytra scarcely so long as the thorax, their common width 
rather greater than their length, densely and rather coarsely 
punctured; the punctuation rugose. Hind body broad, 
slightly contracted at the base, black, with the extreme 
apex rusty, moderately closely and finely punctured ; the 
side margins much elevated. Legs black, tibiz and tarsi 
a little paler; lower part of front tibiz clothed with a 
fulvous pubescence, the front femora in the middle with 
a tubercle beneath. 

In the male the 7th segment beneath is furnished in the 
middle with a longitudinal impression, pointed at the front 
part and there serrate at the margin ; the impressed portion 
is yellowish, and has at its extremity a rather deep notch, 
the sides of which are a little sinuate. 

In the female the hind margin of the 7th segment 
beneath is slightly emarginate at the extremity.

Cryptobium mazillosum, Guérin, is closely allied to the 
C. gigas, and is even a little larger; it has the upper 
surface a little more shining, and the 4th and 5th seg- 
ments of the hind body have, on the upper surface, a 
longitudinal plica at the base in the middle, of which 
there is no trace in C. gigas.

This species is remarkable by its alternate colouration. 
Antenne as long as head and thorax, the base yellow, the 
rest dusky reddish; 3rd joint longer than 2nd, 8th quite as 
long as 4th, 9—11 each a little shorter than its predecessor. 
Palpi yellow; mandibles red. Head rather broader than 
the thorax, about as broad as the elytra, dull slaty-black, 
all the back part densely and distinctly, the front sparingly 
punctured. Thorax rather narrower than the elytra, straight 
at the sides, of a rather shining-red colour, coarsely and 
rather closely punctured, with a line down the middle, 
smooth. Elytra rather longer than the thorax, dull bluish- 
black, densely and rather coarsely punctured. Hind body 
red at the base, the three apical segments blackish ; it 1s 
dull, and finely punctured. Legs yellow. 

In the male the 3rd segment of the hind body has 
beneath, near the extremity, a setigerous puncture ; the 
next segment has a similar puncture, and is moreover in 
the middle more or less backwards, and has the hind 
margin fringed with very long hairs; this lobe is, however, 
variable in its development, and may be entirely absent, 
in which case the long hairs fringing the hind margin 
are also entirely absent; on dissecting an individual in

antennze are yellow and about as long as head and thorax; 
Ist joint not much longer than the two following together, 
3rd joint one and a half times as long as the 2nd, the 
following joints slender and elongate, each a little shorter

about as broad as the thorax, constricted in front of the 
eyes, which are placed about midway at the sides; its sur- 
face is densely punctured, the punctures becoming finer

the eyes is quite opaque; it is nearly black in colour, its 
ereatest breadth just in front of the rounded hind angles. 
Thorax pitchy, shining, much narrower than the elytra, 
longer than broad, a little rounded and narrowed towards 
the front; rather coarsely punctured, but with a broad,

punctured, the punctures rather deep and moderately 
coarse, the interstices not dull,—they are nearly black. 
Hind body very finely punctured, black, and quite dull.

Mas: abdomine segmentis 6° et 7° apicibus excisis. 


Of a dull-reddish colour, with the head and antennze 
darker than the other parts. Antenne not so long as 
head and thorax, dull red; joints 2—10 differing little 
from one another, the penultimate quite as long as broad. 
Head about as broad as the elytra, pitchy, closely and not 
finely punctured; the extreme base impunctate, the three 
frontal eminences large, the central carina of the neck 
elongate, and continued quite to the front as a very narrow 
impunctate line. Thorax quite twice as long as broad, 
broader from the base to near the front, then narrowed to 
the front; it is dull reddish, very densely and finely punc- 
tured, with a raised central carina through its whole 
length, which is, however, but little distinct at the front 
part. Elytra rather shorter than the thorax, dull red, 
densely and finely punctured. Hind body red, densely 
and finely punctured. Legs pale yellow. 

In the male the 6th segment of the hind body beneath 
has a very slight impression along the middle, and a broad 
shallow notch at the extremity; the 7th segment has a 
rather deep triangular notch at the extremity.

The small size, very narrow form, very pale colour, and 

sparing punctuation, render this a very distinct species. 
The antenne are reddish, rather shorter than head and 
thorax. The head is about as broad as the elytra, dark 
reddish, or pitchy colour, shining, the middle and back 
part impunctate; the sides sparingly but not finely punc- 
tured, the three frontal eminences very distinct. Thorax 
yellowish, shining, very sparingly and finely punctured, 
at the back part with a distinct elevation along the middle. 
Elytra yellow, shining, sparingly and finely punctured, 
rather shorter than the thorax. Hind body yellow, scarcely 
shining, but indistinctly punctured. Legs pale yellow. 

In the male the 6th segment of the hind body beneath 
is impressed along the middle, and a little emarginate at 
the extremity of the impression; the 7th segment is 
flattened at the base, and has a rather deep triangular 
notch at the extremity. 

Tapajos; ten specimens. 


LATHROBIUM. 


The genus Lathrobium, consisting of about one hundred 
described species, is distributed throughout the world, 
although comparatively few species are yet known from 
the tropics and subtropical regions. South America is 
the part of the world in which hitherto it might have 
been, with apparent reason, surmised that the genus is 
represented by fewer species than elsewhere; only two or 
three species having been described from these parts, and 
but few others existing, so far as I know, in collections. 
I am enabled here, however, to distinguish no less than 
twenty-five Amazonian species of the genus, so that it 
becomes evident that the want of South American species 
in collections is not really indicative of anything more 
than our very limited acquaintance with the tropical 
Staphylinide. 

Of these twenty-five species the first, L. macrocephalum, 
is about the largest and most peculiar species of Lathrobium 
I am acquainted with, and will probably be ultimately 
considered a distinct genus. Then follow eight species 


250 Mr. D. Sharp’s Contributions to the 


bearing an extraordinary resemblance to one another in 
appearance and general characters, but distinguished 
nevertheless by striking and highly important primary 
and secondary sexual characters. In the case of some 
of these species (L. puncticeps and L. decisum, for in- 
stance), after a very careful examination, I am unable to 
see any satisfactory distinctive characters except the sexual 
ones; and an examination of the male intromittent organ 
has convinced me that it is extremely doubtful whether 
fertilization could be effected by the sexes of different 
species, even if attempted. By this I mean that if, for 
example, the male and female organs in L. opalescens be 
mutually adapted for the facilitation of fecundation, as it 
is only reasonable to suppose is the case, then from the 
great difference we find to exist in the intromittent organs 
of the males of the exactly similar LZ. puncticeps, we are 
fairly entitled to conclude that fecundation of the female 
of ZL. opalescens by it would be difficult. It may, perhaps, 
not be out of place to state here my conviction that these 
modifications of sexual characters will be found to be very 
directly in relation with those “laws of variation,” a 
knowledge of which is so much to be desired for the 
further elucidation of the question of the differentiation 
of species.

The massive head of this species distinguishes it from 
all others of the genus. The antennz are stout, shorter 
than head and thorax, slightly more slender at the ex- 
tremity than the base; 1st joint about as long as the three 
following together, 3rd longer than 2nd, 4—10 differing 
little from one another in length ; 11th joint slender and 
pointed, longer than the 10th, rusty at the extremity. 
The head is rather broader than the thorax; it is a little 
narrowed towards the front, is coarsely and rather closely 
punctured; the punctuation rugose behind the eyes, a 
narrow space along the middle, smooth. Thorax fully

as broad as the elytra, slightly broader than long, a little 
narrowed behind, rather coarsely and irregularly punc- 
tured, a narrow space along the middle smooth, and in 
the centre of this a fine channel; it is black and shining. 
Elytra distinctly longer than thorax, shining pitchy black, 
rather finely and not closely punctured. Hind body 
pitchy, dull, very finely and not closely punctured. Legs 
pitchy, the hind ones reddish; first joint of hind tarsi very 
short, quite hidden by the tibia. In the male the 7th 
segment of the hind body has on the underside, at its 
extremity, a rather deep triangular notch. The 6th seg- 
ment has the hind margin broadly emarginate; in front 
of this it has a broad triangular impression, the middle 
part of which is smooth, and the sides furnished with short, 
coarse, black hairs. 
Ega ; one specimen.

Mas: segmento 7° ventrali apice medio late, sat pro-

Allied to L. brunnipes, but greatly broader, and less 
cylindric. Antennz slender and elongate, rather longer 
than head and thorax, yellow; the 3rd jomt longer than 
2nd, the penultimate joints shorter than the intermediate 
ones. Head nearly as broad as the thorax, the back and 
the hind angles very densely and finely punctured, quite 
opaque, the front part with an opalescent reflection; a 
broad space in the middle smooth, in front of which it is 
sparingly punctured. Thorax quadrate, about as broad as 
the elytra, its length equal to its breadth, regularly but 
not closely punctured, a line along the middle smooth ; it 
is of a pitchy colour, with opalescent reflection. Scutellum 
impunctate. LElytra rather longer than the thorax, mode- 
rately closely, and not altogether finely punctured. The 
hind body is obscurely rufescent, very finely and closely 
punctured, the 7th segment sparingly punctured. Legs 
yellow. 

The male has a very broad but not deep notch at the 


232 Mr. D. Shai Contributions to the 


extremity of the 7th segment, beneath; this notch is of a 
peculiar shape, being somewhat contracted at its entrance, 
in front of it the segment is a little impressed; the 6th 
segment has the hind margin broadly but slightly emar- 
ginate. 

Ega; three male specimens; also one from Santarem, 
but I am not sure that this indication of locality is correct. 

I have also from Ega two female individuals of a 
Lathrobium, which I had at first described under the name 
_of L. guadraticolle, but on re-examination I think it highly 
probable that they may be females of LZ. opalescens, from 
which they differ by being much larger and broader, their 
length being 53 lin. I have ascertained by dissection of 
one of them that it is a female; the ventral plate of the 
7th segment is not rounded in the middle, but is very 
shightly emarginate ; the dorsal lobe of the 8th segment is 
very compressed at the extremity, so that it appears to 
form a sharp longitudinal carina.

Tapajos; a single male. 

I am unable to find any characters except the sexual 
ones to distinguish this species from L. opalescens, but 
these are very marked and important. The notch of the 
7th segment is narrower and deeper, not contracted at the 
entry. The 6th segment has a broad and deep longitu- 
dinal impression along the middle ; the sides of this impres- - 
sion are remarkably abruptly defined, and project beyond 
the hind margin, so as to form an acute angle. 

I have also, from the same locality, a female individual, 
which I believe to be the other sex of this species; it is 
about the same size as the male; it has the hind margin 
of the 7th segment beneath slightly emarginate in the 
middle; it differs from the female described as that of L. 
opalescens by its much smaller size, and by the shorter and 
much less laterally compressed dorsal lobe of the 8th seg- 
ment.

Rather broader and more parallel than L. geminum. 
Closely allied to L. opalescens, but slightly narrower, and 
the male characters different. The antenne are reddish- 
yellow, long and slender, rather longer than head and 
thorax ; the 3rd joint longer than the 2nd; the penultimate 
joints shorter than the intermediate ones. The head is as 
broad as the thorax, pitchy, dull, the sides and back part 
very densely and finely punctured, the middle and front 
part sparingly and more coarsely punctured. The thorax 
is quadrate, about as broad_as the elytra, straight at the 
sides, quite as long as broad, the whole of the sides rather 
‘coarsely and closely punctured, a line along the middle 
smooth; it is of a reddish colour and rather shining. The 
elytra are rather longer than the thorax, reddish, mode- 
rately closely punctured. The hind body is reddish, 
closely and finely punctured. ‘The legs are yellow. 

Tapajos ; numerous specimens. 

This species is so closely allied to the two preceding 
that it is scarcely distinguishable from them except by the 
sexual characters. The male has a rather deep and narrow 
notch, not contracted at the entrance, on the hind margin 
of the 7th segment; the 6th segment has a distinct but ill- 
defined longitudinal impression along the middle, and 
there are indications of a very slight depression on the 5th 
segment, the sides of this having, in fresh specimens, some 
rough black pile, which appears very easily removed. 
The female has the hind margin of the 7th ventral seg- 
ment rounded and entire, and the dorsal lobe of the 8th 
short, and only very slightly laterally compressed towards 
the apex.

234 Mr. D. Sha Contributions to the 


Rather smaller than LZ. puncticeps, and closely allied; 
the head shorter and rather differently punctured, the 
structure of the 6th segment of the hind body in the male 
different. About as large as LZ. brunnipes, but more 
parallel and rather broader. Antenne longer than head 
and thorax, reddish-yellow; 3rd joint longer than 2nd, 
4—10 each a little shorter than the preceding one. Head 
almost as broad as the thorax, the hind angles densely 
punctured; a small space in the middle impunctate and 
shining, the punctures in front of and those surrounding 
this space coarse and not so close. Thorax about as broad 
as the elytra, quite as long as broad, quadrate, of a pitchy 
colour, shining, rather coarsely and closely punctured, with 
a line along the middle smooth. ‘The elytra are longer 
than the thorax, rather closely and distinctly punctured. 
The hind body is pitchy, with the extremity reddish, finely 
and rather closely punctured. The legs are yellow. 

The male has a large deep notch at the extremity of the 
7th ventral segment; the 8th segment has a broad and 
deep longitudinal impression along the middle, at the 
extremity it is deeply emarginate ; the sides of the longitu- 
dinal impression are not abruptly defined (as they are in 
LL. decisum), nor produced beyond the hind margin, and 
their extremity forms a rounded right angle. In the 
female the dorsal lobe of the 8th segment is quite simple, 
not at all laterally compressed; both the dorsal and ventral 
plates of the 7th segment are a little produced and rounded 
at the extremity.

This species resembles exactly the Z. parallelum ; it is 
scarcely smaller, and has the antenne, thorax and elytra 
slightly shorter; but the male characters are remarkable, 
and very different. In this sex the 7th ventral segment 
has a notch similar to that of LZ. parallelum, but it is not

quite so deep, and rather broader at its opening; the 6th 

segment is only indistinctly impressed along the middle, 

but the 5th has a broad and deep impression in the 

middle, and on each side of this, at the extreme base, is a 

deep, abruptly-defined, curved, transverse impression.

Antenne reddish, about as long as head and thorax. 
Head as broad as the thorax; the posterior parts densely 
rugosely punctured, the anterior part sparingly punctured, 
the central part free from punctures. Thorax quadrate, 
just about as long as broad, a broad line along the middle 
impunctate, the sides rather coarsely punctured. Elytra 
slightly longer than the thorax, their punctuation quite as 
coarse as, and similar to, that of the thorax. Hind body 
dull; densely, extremely finely punctured, reddish towards 
the extremity. Legs yellowish. 

The male has at the hinder part of the 7th ventral seg- 
ment a deep notch, the entry of it being broad and quite 
rounded at the sides; the 6th segment is flattened along 
the middle, and distinctly emarginate at the extremity in 
the middle: in these characters 1t approaches considerably 
L.. puncticeps, but the sides of the notch of the 7th seg- 
ment are more cut away, so that it 1s much broader at its 
entry than in L. puncticeps; the 6th segment is less im- 
pressed along the middle, but more deeply emarginate at 
the extremity.

coarsely and not closely punctured; the medial punctures 
at the hind part separated from the others by a narrow, 
smooth space. Elytra rather longer than the thorax, 
finely and not closely punctured, the: punctures indistinctly 
arranged in lines. Hind body with the basal segments 
pitchy, the hind part reddish-yellow, very finely punctured. 
Legs yellow. 

In the male the 6th segment of the hind body beneath 
has a longitudinal impression along the middle ; its hind 
margin is broadly but very shallowly emarginate, the 
emargination limited on each side by a slight projection ; 
the 7th segment has a rather broad and deep notch, the 
front part of which is rounded, and not notched.

hind margin of the 6th segment is also slightly emarginate 
in the middle.

Broader, but only a little longer, than Lathrobium 
longipenne. Antenne yellow, rather longer than head 
and thorax, rather stout; 3rd joint a little longer than 
2nd. Head dark yellow, shining, the front part sparingly 
punctured, a space across the middle impunctate, the 
vertex more closely punctured. Thorax a little longer 
than broad, nearly straight at the sides, very slightly 
narrowed behind, on each side the middle with a row 
of fine punctures, which towards the base are placed in 
a depression; these rows are separated by a broad im- 
punctate central space, and outside them the surface is 
sparingly punctured. The elytra are slightly longer than 
the thorax; they are shining yellow, scarcely lighter in 
colour than the thorax; their punctuation is indistinct, 
consisting of four or five rows of obsolete punctures. The 
hind body is broad in comparison with the front parts ; 
it is reddish in colour, finely and moderately closely 
punctured, and finely pubescent, scarcely shining; the 
legs are pale yellow.

Smaller than Z. longulum, parallel, shining yellow. 
Antenne about as long as head and thorax. Head quite 
as broad as the elytra, straight at the sides and rather 
long, the sides sparingly and rather strongly punctured, 
the middle part impunctate ; it is rather darker in colour 
than the rest of the insect. Thorax rather narrower than 
the elytra, longer than broad, shining yellow, with a line 
of very fine punctures along each side of the middle, and 
some other extremely fine punctures about the sides. 
Elytra rather longer than the thorax, pale yellow, scarcely 
visibly punctured. Hind body scarcely punctured. 

Ega; one specimen (I believe a ¢ ). 

The shining, almost impunctate, hind body renders this 
a very easily distinguished species.

The smallest species of the genus I have seen, Antenne 
short, yellow; 2nd joint scarcely longer than 3rd, the fol- 
lowing joints bead-like, little longer than broad. Head 
shining yellow, sparingly punctured, with the middle part 
impunctate. Thorax about as long as broad, shining 
yellow, with two rows of fine punctures along the middle ; 
the sides sparingly punctured. LElytra scarcely longer 
than the thorax, pale shining yellow, almost impunctate. 
Hind body very finely, sparingly punctured, the apical 
segments more sparingly than the basal ones. Legs pale 
yellow. 

The male has a small notch at the extremity of the 
7th ventral plate of the hind body; this notch is quite 
pointed in front. 

Tapajos; eight individuals. 

This species is smaller than L. chloroticum, and is 
readily distinguished by the much less elongate form of 
the front parts.

the head and hjnd body pale. Antennz yellow, about as 
long as head and thorax; 3rd joint slightly longer than 
Qnd. Head rather small, reddish-yellow, shining, sprinkled 
with rather coarse punctures, which are denser on the 
vertex than elsewhere; the middle part free from punc- 
tures. ‘Thorax slichtly longer than broad, straight at the 
sides, not narrow ed behind, along the middle “with two 
rows of eight or ten fine punctures, aud on each side, near 
the front, with some other punctures. L[Elytra a little

Antenne nearly as long as head and thorax, yellow, 
with the middle joints darker; 3rd joimt slightly longer 
than 2nd. Head rather short and broad, reddish, but 
infuscate, sprinkled with rather coarse punctures, which 
leave a space across the middle free. Thorax shining red, 
oblong, longer than broad, a little rounded at the sides, 
with two rows of about seven punctures along the middle, 
and also with a few punctures on each side, near the front 
part. Elytra about as long as, but distinctly broader than 
the thorax; their apex pale yellow, the base reddish, along 
the middle of each a dark patch; shining, very obsoletely 
and sparingly punctured, the punctures consisting of a 
sutural series and some extremely indistinct serial punc- 
tures near the sides. Hind body reddish, a little dilated 
in the middle, closely and finely but a little roughly punc- 
tured, a little shining, the apical segment infuscate. Legs 
pale yellow. Underside of head s sparingly and finely punc- 
tured, very shining; underside of hind body rather closely 
and somewhat coar sely punctured, but shining.

is also rather coarsely punctured. Thorax shining reddish, 
a little rounded at the sides, and slightly narrowed behind; 
along the middle with two rows of about eight punctures,— 
these rows a little approximate behind; also on each side 
towards the front with a few punctures, Elytra slightly 
longer than the thorax, the larger basal half blackish, the 
smaller apical half pale yellow, shining, with a sutural row 
of punctures and three rows near the side, which are but 
indistinct, and become quite obsolete before the extremity. 
Hind body red-yellow, rather closely and finely punctured, 
but still a little shining, the extremity a little infuscate. 
Legs pale yellow. Under face of hind body more coarsely

darker in the middle, and have the apical joints less elon- 
gate; the thorax is less parallel at the sides; the hind 
body not quite so densely and finely punctured, and so 
more shining. The male characters are very similar in 
the two species. From ZL. pictum it may be distinguished 
by the coarser punctuation of the underside of the head,

DOoLICcAON. 


This generic name was first applied by Laporte to a 
large Staphylinid from the Cape of Good Hope, and 
Erichson afterwards included under it some European 
insects very different in appearance from the South 
African species above alluded to. The genus now com- 
prises over twenty species, most of which are from the 
Mediterranean area, with one or two from India and 
Australia. The insect I here describe as Dolicaon distans 
is very different in appearance from any of the forms 
hitherto included in the genus, though in its structure it 
appears to be rather similar to the Dolicaon lathrobioides, 
from the Cape of Good Hope. As the genus already 
contains species very different in appearance, some of 
which will probably be grouped as distinct genera, there is 
no harm in my adding to their number a distincf South 
American form, which appears to offer all the recorded 
characters of the genus. This insect, as I have above 
remarked, has a peculiar facies, which at first reminds one 
of the genus G¢tdichirus, and I should not feel at all sur- 
prised if it ultimately prove to mimic or resemble some 
Amazonian species of that group.

closely punctured, the punctures becoming less numerous 
towards its middle. Thorax pitchy or dark reddish, rather

these sparingly and irregularly punctured, Elytra very

hind margin broadly yellow ish ; ; on each is three series of 
coarse punctures, and a few punctures external to these; 
these series are abbreviated, especially the external ones, 
and the sutural one is placed in a depression. Hind body 
a good deal dilated towards the extremity, closely and 
finely punctured, dull, with a fine greyish pubescence. 
Legs yellow, with the coxe pitchy reddish; the front

ScOP.EUS. 


This is another widely distributed genus, and one of 
which only two or three species have as yet been described 
from South America. Nevertheless, it is probable that 
species of it are numerous there, and I here describe seven. 
Of these seven the three last, viz., S. distans, S. laxus 
and S. levis, depart widely in facies from the ordinary 
species of the genus, and suggest to one greatly, at first 
sight, our European T'achyusa ferialis; the polished 
surface, elongate and loosely articulated form, and the 
greatly developed legs, distinguish these species from the 
ordinary forms of the genus. As, however, they possess 
the tricuspidate ligula, which is so characteristic a mark of 
Scopeus, as well as all the other characters mentioned in 
systematic works as distinctive of the genus, I have not 
thought it advisable to establish a new genus for them. 
A kindred form has, indeed, been already described by 
Erichson as a Scopeus; at least, I suppose from his 
description of S. pulchellus, from Columbia, that it per- 
tains to the same group as the species in question. I have 
also some other species allied to these insects from Rio de 
Janeiro. The S. chloroticus is also a very peculiar form, 
and one which may ultimately give rise to the establish- 
ment of a separate genus, which, to judge from facies, 
would probably be as much allied to Lathrobium as to 
Scop@us.

breadth in front of the middle, greatly narrow ed to the 
front, and a good deal narrowed towards the base; ex- 
tremely finely carinate along the middle, the carina being 
only distinctly visible near the base, in consequence of the 
surface there being a little flattened or depressed on either 
side; colour and punctuation similar to the head. Elytra

longer than broad, distinctly narrower than the elytra; its 
greatest breadth much in front of the middle, much nar- 
rowed to the front, but only slightly towards the base; the 
surface very obsoletely punctured, so as to be a little 
shining, with faint indications of two fovex at the base in 
the middle. Elytra only slightly longer than the thorax, 
extremely finely and indistinctly punctured, depressed at

Obs.—This minute species is peculiar, and probably 
generically distinct from the ordinary Scopei; the form of 
the front angles of the thorax is dissimilar from what is 
usual in Scopeus ; the general appearance is much that 
of an extremely minute Lathrobium, but, as the structure 
of the tarsi is like that of Scopeus, it may be placed in 
that genus till its characters can be more fully ascertained. 


5. Scopeus distans, n. sp.  Rufo-testaceus, nitidus, 
fere impunctatus, parcius setosus; antennis apice pallidiori- 
bus, elytris disco abdomineque apice obscurioribus ; pedibus 
elongatis, tarsis gracilibus. Long. corp. 2 lin. 

Narrow and elongate in form. Antenne about as long 
as head and thorax, a little thickened towards the ex- 
tremity, reddish, with the four or five apical joints pale 
yellow ; 8rd joint elongate, a good deal longer than 2nd; 
10th joint a little longer than broad. Head rather long 
and narrow, about as ‘broad as the elytra, entirely rounded 
at the vertex; the surface shining reddish-yellow, im- 
punctate, with some upright black sete, and with a fine 
and scanty yellow pubescence. Mandibles each with 
three large sharp teeth in the middle. Thorax elongate 
and narrow, much narrower than the elytra, very convex, 
the greatest width in front of the middle, and thence 
much narrowed towards the front and a good deal to- 
wards the base; impunctate, colour and sete as on the 
head. LElytra long and narrow, a little longer than the 
thorax, shining and impunctate, yellow, but largely dark 
chestnut about the middle. Hind body narrow at the 
base, a good deal broader towards the extremity, yellowish, 
with the 6th segment, except its hind margin, infuscate; 
its punctuation and pubescence very fine and indistinct. 
Legs yellow, long, and rather stout; the hind tarsi long 
and slender, more than half the length of the tibize. 

In the male the ventral plate of the 7th segment of the 
hind body has a broad notch or emargination at the 
extremity, 

Tapajos; several individuals. 


6. Scopeus laxus, n, sp. Rufo-testaceus, nitidus, fere 


Staphylinide of the Amazon Valley. 253 


impunctatus, parcius setosus; antenuis apice pallidioribus, 
elytrorum disco abdominisque apice obscurioribus. Long. 
corp. 1? lin, 

This insect so extremely resembles S. distans, that to 
describe it would be in most points to repeat the descrip- 
tion of that species ; it is, however, rather less elongate in 
all its parts, so that the 10th joint of the antenne is hardly 
as long as broad, and the hind tarsi are distinctly shorter 
when compared with those of S. distans. 

In the male the hind margin of the ventral plate of the 
6th segment of the hind body is broadly but not deeply 
emarginate at the extremity, and the 7th has a small 
notch, and the sdeagus itself is considerably shorter than 
in S. distans. 

Tapajos; six male, two female individuals. 


7. Scopeus levis, n. sp. Rufo-testaceus, nitidus, fere 
impunctatus; elytris abdominisque apice nigricantibus, 
femoribus quatuor posterioribus apicem versus _leviter 
infuscatis. Long. corp. 14 lin. 


Closely allied to S. distans and laxus, but considerably 
smaller. Antenne rather short, a good deal shorter than 
head and thorax, a little thickened towards the extremity, 
reddish, with the apical joints a little paler than the middle 
ones ; 3rd joint shorter than 2nd, 8—10 not so long as 
broad. Head broader than the thorax and as broad as 
the elytra, rounded at the sides, but with the vertex a 
little truncate, the surface shining red, without sculpture. 
Thorax longer than broad, very convex, a good deal nar- 
rower than the elytra, much rounded at the sides, being 
greatly narrowed towards the front and a good deal to- 
wards the base, shining red, impunctate. LElytra scarcely 
longer than the thorax, shining, blackish, without sculp- 
ture. Hind body narrow at the base, a good deal dilated 
towards the extremity, the basal segments reddish, the 
apical ones blackish ; the surface very finely and indis- 
tinctly punctured. Legs yellow, the outer portion of the 
four posterior femora slightly infuscate; the hind tarsi 
slender and long, a good deal more than half the length of 
the tibize. 

Amazons; a single female, without more special 
locality. 


254 Mr. D. Shafts Contributions to the 


LITHOCHARIS. 


The species of this widely-distributed genus are no- 
where more numerous than in South America; thirteen 
species have already been described by Erichson from 
Columbia, so that it is not surprising that I should here 
describe twenty-two species from the Amazons. Among 
these twenty-two species there is sufficient variety in 
structural points to render it probable that some of them 
will ultimately be referred to new genera. The ZL. munda 
bears considerable resemblance in general appearance to a 
Scopeus, and it is probable that this resemblance is indi- 

cative of a real affinity. The five species (L. oculata, 
quadrata, egena, h umilis and ardua) with setose antenn, 
the two basal joints of which are stout, the others slender, 
may also perhaps form a distinct genus; indeed, Kraatz 
has already founded a genus ( Thinochar ts) for some 
Ceylon species possessing “this structure of the antenne ; 
but, as it is doubtful whether the South American species 
I am alluding to are really congeneric with the Eastern 
Thinocharis, and as Erichson has already described as 
members of the genus Lithocharis several Columbian 
species with similarly-formed antenne, I have preferred 
associating the new forms here described with the cognate 
forms from a neighbouring locality. 

LI. discedens and L. connexa are distinguished by a 
peculiarity of structure of the 4th joimt of the hind 
and middle tarsi, and are probably qe related to the 
Columbian L. biseriata, Er. 

The most peculiar of the new species I here describe 
are the four I have placed at the end of the genus, viz., 
LL. polita, germana, pagana and picta. ‘These four 
species I anticipate will be found to be closely allied to 
LL. macularis and L. angularis, Kr., from Venezuela and 
Columbia. Mr. Solsky, who has in the Hor. Soc. Ent. 
Ross. (v. p. 142, pl. iv.) described and figured the 
trophi of Dacnochilus letus, Leconte, has suggested that 
Erichson’s L. angularis should be placed in “that genus ; 
and in the Munich Catalogue this has been done. On 
comparing the parts of the mouth of the species here 
described with Solsky’s figures, I find them to be far from 
agreeing therewith; the labrum in the four species I 
describe possesses an acute stout tooth on either side of 
the central notch, while in Solsky’s figure the lobes are 
quite destitute of this; the 3rd joint of the maxillary 


Staphylinide of the Amazon Valley. 255 


palpi is more slender than in Solsky’s figures, and the 
4th joint, which is concealed within the 3rd, appears to 
be much more slender and acuminate; the last joint of 
the labial palpi is more slender, quite cylindrical, and 
only about half as long as the preceding joint. I am, 
therefore, unable to consider these species as congeneric 
with the North American Dacnochilus letus, and prefer 
to place them for the present in the genus Lithocharis 
rather than establish a new genus for them. 

Krichson describes the Z. macularis and L. angularis 
as possessing a labrum similar in structure to the four 
species I have here described, and I have therefore great 
doubts whether the Z. angularis is correctly referred to 
Dacnochilus. J have another closely allied species of the 
group from Rio de Janeiro. 


1. Lithocharis latro, n. sp. Lata, depressa, fusco- 
ferruginea, antennis rufis, pedibus testaceis, dense sub- 
tilissime punctata, opaca; elytris dilutioribus, thorace 
paulo longioribus; tarsis anterioribus dilatatis. Long. 
corp. 34 lin. 

Antenne rather slender, reddish, 1} lin. in length, not 
at all thickened towards the extremity; 3rd joint dis- 
tinctly longer than 2nd, 5—10 each slightly shorter than 
its predecessor, 10th longer than broad. Palpi red, last 
joint elongate and slender. Labrum red, with a single, 
short, obscure tooth in the middle, on either side of which 
it is a little emarginate. Mandibles red, the left with 
three, the right with four, distinct teeth. Head large, 
slightly broader than the thorax, the hind angles slightly 
produced, so that the vertex is a little emarginate, very 
densely and finely punctured. Thorax very nearly as 
long as broad, fully half a line in length, the sides a little 
narrowed behind, very densely and finely punctured, with 
a very narrow indistinct line along the middle. Elytra 
8 lin. in length, taken together rather broader than long, 
paler in colour than the head and thorax, densely and 
finely punctured. Hind body broad, very densely and 
finely punctured. Legs yellow; front tarsi moderately 
dilated. 

In the male the ventral plate of the 6th seement of the 
hind body is rounded in the middle and emarginate on 
each side ; the ventral plate of the following segment has 
a very broad and deep excision in the middle. 

Ega; a single specimen. 


256 Mr. D. Shas Contributions to the 


Obs.—This species much resembles the Eastern L. 
staphylinoides, but has very different male characters. 
L. hepatica, Ex., from Columbia, appears to be an allied 
species, and I have another closely allied, but distinct, 
species from Rio de Janeiro. 


2. Lithocharis simplex, n. sp.  Rufescens, capite, ely- 
trorum apiece, abdomineque apicem versus infuscatis, 
pedibus testaceis, dense subtilissime punctata; prothorace 
quadrato, linea media impunctata. Long. corp. 12 lin. 


Antenne moderately long, rather stout; 3rd joint about 
equal to 2nd, 5—9 each slichtly broader and shorter than 
its predecessor, 10th about as long as broad. Mandibles, 
palpi and labrum reddish. Head infuscate, large, quite as 
broad as the thorax, densely and extremely finely punc- 
tured. Thorax not quite so long as broad, straight at the 
sides, densely and very finely punctured; rather lighter 
than the head in colour, with a smooth impunctate line 
along the middle. Elytra a good deal longer than the 
thorax and distinctly broader, reddish at the base, in- 
fuscate towards the extremity; densely and finely punc- 
tured, but the punctuation more distinct than on the head 
and thorax. Hind body reddish, with the penultimate 
segments infuscate, densely and finely punctured. Legs 
yellow. 

I do not know the male of this species, but in the female 
the anterior tarsi are not in the least dilated. 

St. Paulo, three individuals; Ega, one individual. 

This species is, in form and sculpture, closely allied to 
our European ZL. ochracea, but it has the labrum quadri- 
denticulate, it being furnished in the middle with four 
short, stout, not very distinct teeth; the mandibles are 
very stout at the base, and beyond the stout basal portion, 
are armed, the left with one, the right with two teeth. 


3. Lithocharis condita,n.sp. Piceo-testacea, antennis 
rufis, pedibus testaceis, elytris obscure testaceis, dorso 
infuscatis, dense subtilissime punctulata, subopaca ; pro- 
thorace media linea obscura glabra; elytris thorace 
longioribus; tarsis anterioribus simplicibus. Long. corp.

Antenne moderately long, rather stout, reddish ; 3rd 
joint about as long as 2nd; ‘Loth joint distinctly broader 
than the 4th, about as long as broad. Mandibles red, 


Staphylinide of the Amazon Valley. 257 


short and robust, their teeth small. Head pitchy, densely 
and very finely punctured, very delicately pubescent, 
scarcely shining. Thorax about as long as broad, scarcely 
broader than the head, and distinctly narrower than the 
elytra; densely and extremely finely punctured, so that an 
impunctate line along the middle is very indistinct, the 
colour scarcely paler than that of the head. Elytraa good 
deal longer than the thorax, obscure testaceous, with the 
disc a little infuscate, closely and finely punctured. Hind 
body very densely and finely punctured, quite opaque. 
Legs yellow; front tarsi not in the least dilated, hind tarsi 
with the basal joint a good deal longer than the 2nd. 

The male characters are very slight; the ventral plate 
of the 7th segment of the hind body being a little emargi- 
nate at the extremity in that sex. 

St. Paulo; three individuals. 

This species appears to be closely allied to the common 
and widely distributed L. ochracea, but is so much 
smaller that it cannot be confounded therewith. L. infus- 
cata, Ex., from Columbia, is probably a very close ally of 
this species, but according to Erichson’s description differs 
in the colour of the hind body. 


4. Lithocharis diffinis, n. sp. Rufescens, capite, 
elytrorum apice abdomineque apicem versus plus minusve 
infuscatis, pedibus testaceis, dense subtilissime punctata ; 
prothorace quadrato, linea media impunctata. Long. 
corp. 2 lin. 


Similar in size, form and punctuation to L. ochracea, 
but with the head larger, it being almost broader than the 
thorax ; rather larger than L. simplex, and with the labrum 
furnished in the middle with two obscure distant teeth; in 
other respects it appears to agree exactly with L. stmplezx. 

The 7th segment of the hind body has the hind margin 
of the ventral plate quite simple in the male, so that I am 
not aware of any external character by which the sexes 
can be distinguished. 

Ega; two specimens.

Antenne red, rather short and stout; 3rd joint scarcely 
longer than 2nd, 10th not quite so long as broad. Head 
large, slightly broader than the thorax, pitchy red; the 
eyes large and rather prominent, the hind angles slightly 
swollen, so that the vertex appears a little emarginate in 
the middle; the surface densely, finely and obsoletely 
punctured, opaque. Thorax scarcely so long as broad, 
straight at the sides, the front obliquely truncate on each 
side; the colour slightly paler than that of the head, the 
surface densely and very obsoletely punctured, opaque, but 
with a shining impunetate line along the middle. Elytra 
a little longer and a little broader than the thorax, of a 
sordid-testaceous colour, but with the apex quite pale, 
finely and closely punctured. Hind body pointed at the 
extremity, densely and finely punctured. Legs yellow. 

Ega; a single specimen. 

Obs.—I do not know the sex of this individual, nor 
have I been able to examine the labrum and mandibles; it 
is excessively close to LZ. diffinis, but has the head rather 
larger and the eyes more prominent, and the vertex more 
emarginate, and the extremity of the elytra paler; the 
front tarsi are not in the least dilated. It is similar to 
LL. ochracea, but has the head larger and the front of the 
thorax more oblique on each side. 


6. Lithocharis sobrina, n. sp.  Fusco-rufa, opaca, 
antennis rufis, pedibus testaceis; capite, thorace, abdo- 
mineque subtilissime punctatis; elytris subtiliter sed magis 
distincte punctatis, fuscis, lateribus margineque apicali 
testaceis. Long. corp. 2} lin. 


. This species is extremely similar to Z. diffinis and 
I. comes, but has the elytra differently coloured, their 
sides being obscurely yellow, while the sutural portion is 
largely infuscate. ‘This infuscation does not, however, 
reach to the extremity, which is similar in colour to the 
lateral margins. 

There are no external characters to distinguish the 
male. 

Para; four individuals, collected by Mr. Smith. 

Obs.—Like the ZL. diffints and L. comes, this insect 
appears to be closely allied to LZ. ochracea. It has the 
antennz longer than ZL. comes, joints 4—10 being each 


Staphylinide of the Amazon Valley. 259 


distinctly a little longer. Notwithstanding its great re- 
semblance to L. diffinis, the sdeagus is different enough 
in the two to make me feel sure they are quite distinct 
species, the appendage with which it is furnished being 
short and hastate in ZL. sobrina, while it is elongate and 
slender in L. diffinis, 


7. Lithocharis crassula, n. sp. Crassiuscula, castanea, 
pedibus testaceis; capite thoraceque nitidulis, transversis,

corp. 2 lin. 

Antenne short, reddish-yellow; 3rd joint about equal to 
2nd, 4th shorter than 3rd, 5—9 differing but little from 
one another; the 9th and 10th, however, slightly stouter 
than the others, about as long as broad. Labrum with a 
small notch in the middle, without teeth. Mandibles with 
the basal part stout, each with three teeth; on the left the 
two upper ones very small, on the right the upper one 
small. Head broad and short, about as broad as the 
thorax, the hind margin distinctly emarginate ; the surface 
rather coarsely and closely punctured, the punctures 
wanting on a space in the centre. Thorax as broad as 
the elytra, a good deal broader than long, scarcely 
narrowed behind, the front a little rounded; the surface 
coarsely and rather closely punctured, with a smooth line 
along the middle. Elytra a little longer than the thorax, 
moderately closely and not coarsely punctured, only a little 
shining. Hind body a good deal pointed at the extremity, 
densely and finely punctured, not shining. Legs yellow; 
front tarsi dilated, hind tarsi slender but not very long; 
4th joint simple. 

In the male the hind part of the ventral plate of the 
7th segment of the hind body has a moderately large notch 
in the middle. 

Tapajos, one male; St. Paulo, one female.

about as long as the two preceding together. Labrum. 
with two distant obscure teeth in the middle. Mandibles 
each with three teeth in the middle; on the left mandible 
the centre one is smaller, on the right mandible longer 
than the others. Head quadrate, rather convex, the vertex 
with a deep, short longitudinal impression in the middle; 
the surface shining, at the sides more densely and coarsely 
punctured than in the middle; the eyes rather small. 
Thorax distinctly narrower than the elytra, not quite so 
long as broad, distinctly narrowed behind, the front a little 
oblique on each side, the front angles rather prominent ; 
the surface shining, rather finely and indistinctly punc- 
tured, with a very ‘obsolete line along the middle. Elytra 
red, shining, a little longer than the thorax, rather 
sparingly and indistinctly punctured, impressed on each 
side the suture at the base, and each with two indistinct 
abbreviated series of punctures on the disc. Hind body 
rather darker than the front parts, but with the apex paler, 
a little contracted at the base, closely and finely punctured. 
Legs yellow, front tarsi only slightly dilated; underside 
of head coarsely and closely punctured. 

Ega; a single individual, of whose sex I am in doubt, 
the hind body showing nothing peculiar in structure.

Antenne reddish, rather slender; 3rd joint about equal 
to 2nd, 4th shorter than third, 5—10 differing little from 
one another, 10th about as long as broad. Labrum 
reddish, prominent in the middle, and there with three 
small teeth. Mandibles and palpi red, the former each 
with three teeth. Head rather long, a little narrowed 
towards the front, a little broader than the thorax, and 
quite as broad as the elytra; nearly truncate behind, with 
the angles rounded, dull reddish in colour, finely and very 
densely punctured, ‘the eyes small. Thorax a little nar- 
rower than the elytra, almost as long as broad, a little 
narrowed behind, the front distinctly but not greatly 
oblique on each side; the surface obscure reddish, finely 
and very densely punctured, without distinct impressions

or line along the middle. Elytra distinctly longer than 
the thorax, and rather darker in colour, very densely, 
finely and indistinctly punctured, quite dull. Hind body 
rather slender, very densely and finely punctured. Legs 
yellow ; front tarsi rather short, distinctly dilated; 4th 
joint of hind tarsi small, simple. 

The male has a very slight emargination at the extremity 
of the ventral plate of the 7th segment of the hind body. 

Ega; two individuals. 


10. Lithocharis compressa,n.sp. Depressa, ferruginea ; 
erebre subtiliter punctulata, subopaca. Long. corp. 14 lin. 

Antenne short, red, scarcely at all thickened towards 
the extremity ; 10th joint slightly transverse. Head large 
and flat, quite as broad as the elytra, reddish, finely 
and closely punctured, the vertex distinctly emarginate. 
Thorax rather narrower than the elytra, rather broader 
than long, distinctly narrowed behind, reddish ; extremely 
finely punctured, with an extremely fine channel near the 
base, and a very indistinct impression at the base on each 
side of the middle. Elytra a good deal longer than the 
thorax, closely and_ finely punctured, infuscate-reddish. 
Hind body reddish, densely and finely punctured. 

Anané; a single female taken by Dr. Trail on the 6th 
September, 1874. 

Obs.—This species greatly resembles L. integra, and 
appears structurally closely allied thereto, but it is smaller 
and more depressed, and has the surface less densely punc- 
tured, so that it is less opaque. 


11. Lithocharis discedens, un. Sp. Ferruginea, elytris, 
antennis, pedibusque rufescentibus, opaca, dense punctata ; 
capite thoraceque dense rugulose punctatis, hoc basi qua-

4th joints about equal to one another, 5—10 each a little 
shorter than its predecessor, 9 and 10 scarcely so long as 
broad, Labrum slightly emarginate in the middle, with- 
out teeth. Mandibles red, each with three teeth; the 
middle tooth on the left mandible very small, on the right 
one longer than the others. Head broad and short, very 
densely and rugosely punctured, the punctures finely ocel- 
lated, the interstices very fine. Thorax almost as long as

broad, narrowed behind the front, on each side very 
oblique, the punctuation similar to that of the head; the 
extreme base with four small fovez, the middle with a short 
and excessively fine channel. Elytra brighter red than the 
head and thorax, distinctly longer than the thorax, closely 
punctured, each ‘with three series of punctures ; one along 
the suture, two along the middle, these rows not reaching 
to the apex. Hind body very densely and finely punc- 
tured, quite opaque. Legs reddish. Front tarsi short, 
moder: ately dilated. 

Ega and Tapajos ; two individuals. 

Obs.—The structure of the 4th joint of the middle and 
hind tarsi is peculiar in this species; though narrow, this 
joint is on the upper side deeply bilobed. I do not know 
the sex of my individuals, but I think them to be males, 
though they have no external abdominal character to indi- 
cate this. 


2. Lithocharis convera,n.sp. Ferruginea, elytris rufes- 
centibus, antennis pedibusque rufo-testaceis ; capite dense

Long. corp. 1}? lin. 


Antenne reddish-yellow ; 3rd joint slightly longer than 
the adjacent ones. Labrum not emarginate in the. middle, 
without distinct teeth. Head very densely punctured. 
Thorax closely punctured, the punctures much finer than 
on the head, and towards the front not so dense as at the 
base, so that the front part is slightly shining, the extreme 
base with four puncture-like foveex, the outer ones being 
very indistinct. Elytra finely and indistinctly, not very 
closely punctured ; a little shining, with traces of a sutural 
and two dorsal series of punctures. Front tarsi distinctly 
dilated. 

In the male the ventral plate of the 7th segment of the 
hind body is slightly emarginate in the middle at the 
extremity. 

Amazons; two male individuals, without special locality. 

Obs.—This species is rather smaller than L. discedens, 
to which it is closely allied; but besides some peculiarities 
of sculpture, which readily enough distinguish it, it has 
the labrum rather differently formed. 

Besides the two individuals above described, I have also 


Stuphylinide of the Amazon Valley. 263 


from Ega a specimen rather smaller and more finely 
punctured and paler, which I believe to be an immature 
variety of L. discedens.

joints 3—10 setose. Labrum red, furnished in the middle 
with two distinct, approximate, stout teeth. Mandibles red, 
each with two large, sharp teeth. Head short and broad, 
broader than the thorax, eyes large and convex, reaching 
to within a short distance of the vertex, which is nearly 
truncate, the surface densely and finely punctured. Thorax 
not so long as broad, the front and front angles rounded, 
the sides much narrowed towards the base; the surface 
covered with fine, moderately close asperities, and along 
the middle with a fine channel, which is deepest in its 
hinder part. Elytra a good deal longer than the thorax 
and rather paler in colour, each one with the external 
angle broadly pale yellow; the surface rather closely 
and finely punctured, the punctuation becoming obsolete 
towards the extremity. Hind body very densely and 
finely punctured. Legs yellow; front tarsi not dilated, 
hind tarsi with the fourth joint small and simple. 

Ega; three ‘ndividuals, of whose sex I am in doubt.

asperities, along the middle with a fine channel, which 
does not reach the front, but is continued to the front as a 
very fine, smooth line. Elytra a good deal longer than 
the thorax, rusty testaceous, their sculpture similar to that

tate, except for some setigerous punctures at the sides. 
Elytra a little longer than the thorax, quadrate, reddish; 
each with a dark mark on the middle towards the extre- 
mity, smooth and shining, each with a series of fine distant 
punctures close to the suture, and with two or three other

7th segment of the hind body has on the underside a 
broad but not deep notch at the extremity, which is con- 
tinued forwards as a shallow, longitudinal depression. In

sutural and two or three lateral rows of fine distant seti- 
gerous punctures. Hind body finely but not densely 
punctured; the 6th segment with a large spot on either 
side blackish. 

In the male the front tarsi are distinctly dilated; the 
ventral plate of the 6th segment of the hind body has an 
extremely slight emargination in the middle at the extre- 
mity; the ventral plate of the 7th segment has a small 
emargination at the extremity and in front of this a short 
smooth depression. In the female the front tarsi are 
scarcely dilated. 

Tapajos; two male, three female specimens. 

Obs.—Though excessively similar in general appear- 
ance to LZ. polita and L. germana, this species is readily 
to be distinguished from them by the peculiar tubercle on 
the mentum.

as long as the thorax, shining red, with a large dull mark 
extending obliquely from the shoulder to the inner angle, 
the series of punctures along the suture and towards the 
sides distinct. Hind body finely and rather closely punc- 
tured, reddish, with the anterior outer angle of each seg- 
ment blackish; the 6th segment entirely blackish except 
towards the hind margin.

Obs.—The single individual I have seen of this species 


270 Mx. D. Shi#’s Contributions to the 


appears to be a female and has the front tarsi scarcely 
dilated; it comes extremely close to the LL. pagana, but 
differs in having the head slightly shorter and the hind 
body a little more closely punctured as well as in its dark 
markings. The tuberculate mentum readily distinguishes 
it from LZ. polita and L. germana. 


STILICUS. 


The species of this genus found by Mr. Bates are only 
two in number, and are evidently closely allied to the two 
species S. jugalis and S. carinatus described by Erichson 
from Columbia. I have also three or four other closely 
allied species from Brazil, so that the genus is probably 
quite as well represented in South America as in any 
other part of the world; the species, though widely distri- 
buted on the globe, being nowhere numerous.

Antenne rather long, quite yellow; 3rd joint scarcely 
longer than 2nd; 10th joint quite as long as broad; 11th 
joint rather long, nearly as long as the two preceding to- 
gether. Palpi yellow, slightly infuscate. Labrum large. 
Head dull blackish, rather elongate, very densely punc- 
tured; the punctures on a small space on the middle 
coarser than elsewhere, so that this spot is a little shining, 
but none of the punctures are wanting, neither are the 
interstices there any broader. Thorax just } lin. in length, 
strongly angulated at the sides and abruptly narrowed 
towards the front, densely punctured and with a shining 
conspicuous smooth line along the middle. Elytra just 
as long as the thorax and about as broad as long, a little 
shining, of an obscure brassy colour, with the extremity 
pale yellow ; ; rather sparingly and not coarsely though dis- 
tinctly punctured. Hind body densely and finely punc- 
tured, slightly shinmg. Legs clear yellow. 

Kea; a single female specimen. 

This species is rather larger than the European S. 
orbiculatus: its antenn are longer, the terminal joint or 
the maxillary palpi is more elongate and more linear, the 
head behind the eyes is longer and less truncate, the 


Staphylinide of the Amazon Valley. 271 


thorax more abruptly angulated at the sides and consider- 
ably longer, the hind tarsi more slender and rather longer.

fortiter profundeque punctatis, apice testaceis. Long. 
corp. 23 lin. 

Antennz short, reddish, the middle joints infuscate. 
Palpi infuscate-reddish. Labrum large. Head broad 
and short, very densely punctured, dull, a little shining 
on a small place in the middle, where the punctures are 
a little coarser. Thorax black, much angulated at the 
sides and abruptly narrowed in front; densely punctured, 
with a conspicuous shining line along the middle. Elytra 
quite as long as the thorax, distinctly brassy, with the 
extremity yellow; distinctly shining, deeply and rather 
coarsely punctured, the punctuation absent on the pale 
extremity. Hind body densely punctured, a little shining. 
Legs yellow. 

Kga; a single female individual. 

This species is about the size of S. orbiculatus, and the 
head is very similar in form thereto, but the palpi are 
darker, with the apical joint more linear and elongate ; 
the thorax is more angular at the sides, and the punctuation 
of the elytra is greatly more conspicuous. From S§. ama- 
zonicus, the smaller size, differently-shaped head, shorter 
antennz, and more coarsely punctured elytra of S. punc- 
tatus, readily distinguish it.

272 Mr. D. SM p’s Contributions to the 


maxillary palpi a little dilated in the middle on the inner 
side and nea at the extremity; 4th joint very minute. 
Head with a slender neck. Thorax subglobose, the horny 
portion of the prosternum large, so that in the natural 
position it extends as far back as the front edge of the 
mesosternum ; but the side pieces of the prothorax are not 
contiguous with this, so that the anterior coxal cavities 
are quite open behind. Mesosternum large, forming a 
well-marked neck. ‘arsi apparently only four-jointed, 
the 3rd joint being short, especially on the upper side; its 
lower surface longer and hairy, and the 4th joint consisting 
of a membrane, hairy beneath, enwrapping the sides and 
undersurface of the fifth joint on the hind foot; the basal 
joint is as long as the rest of the tarsus. Front tarsi 
undilated in both sexes. 

This genus is allied to Suntus, but cannot be amalga- 
mated therewith, owing to the different structure of the 
prosternum. Its facies and form are also different, and 
approach Lithocharis and Scopeus. It forms a connecting 
link between the Pederide with closed anterior coxal 
cavities and those in which these are widely open, and 
its position in the usually adopted scheme of classification 
is between Lithocharis and Sunius. ‘The above characters 
are drawn from a Rio de Janeiro species, of which I give 
a diagnosis in the subjoined note.*

and placed much nearer the antennex than the vertex ; the 
surface rather closely and moderately coarsely punctured, 
with simple impressed punctures, castaneous in colour, 
‘shining, and bearing a fine erect pubescence. Thorax 
much narrower than the elytra, nearly as long as broad, 
without angles, rounded in front, narrowed towards the 
base, and gently curved at the sides; its colour and sculp- 
ture similar to those of the head, but with an impunctate 
line along the middle, not reaching however to the front. 
Elytra longer than the thorax, rather inflated, yellowish 
in colour, but paler at the extremity and slightly clouded 
about the middle, shining and almost impunctate. Hind 
body broad and short, strongly margined, the segments 
very finely and indistinctly punctured; the 6th infuscate, 
but pale at the extremity. Legs slender, pale yellow. 

In the male the ventral plate of the 6th segment of the 
hind body is emarginate at the extremity; the apical seg- 
ments are retracted in my only individual.

ECHIASTER. 


Of this remarkable genus only six species have been yet 
described, viz., three fom Northern South America, one 
from Chil: and two from the United States of North 
america. I here describe ten (or perhaps only nine) new 
species, which show a striking variation in form of different 
parts of the body, and leave no doubt that many other 
species will be discovered ; indeed, I have already two 
others from Rio Janeiro, very dissimilar to any here 
described. 

A highly important: character of the genus appears 
hitherto to have escaped notice, viz., that the prothorax 
behind the front coxe is horny. This character, in con- 
junction with the others indicated for the genus, gives 
it an isolated position in the Pederide, and renders it 
probable that it will prove to be one of the most important 
of the genera of South American Staphylinide ; and also 
that, notwithstanding the extension of one or two species 
into Chili and N orth America, Hehiaster will be one of 
the most characteristic genera of the Austro-Columbian 
Coleoptera. WKraatz has described a genus from East India 
(Sclerochiton, Kr. Staph. Faun. von Ostind. pl. ii. f. 8), 
which appears to possess several points of relationship with 
Echiaster, and to be at present its nearest known ally; it 
is doubtful, however, to what extent the resemblances be- 
tween the two genera indicate a real affinity between them. 
Kraatz indeed in his figure and description gives us no 
reason to suppose that Sclerochiton possesses that peculiar 


Staphylinide of the Amazon Valley. 275 


tubular elongation of the apical abdominal segments which 
is one of the most striking and easily-perceived characters 
of Echiaster.

vatis, subtus oculis dilatatis. Long. corp. (abdomine 
extenso) 14 lin. 

Antenne about as long as head, yellowish ; Ist and 2nd 
joints short and stout; 3rd joint small, rather shorter and 
much more slender than 2nd ; 4—9 each slightly shorter 
than its predecessor, the penultimate joints rather strongly 
transverse; 11th joint rather short. Maxillary palpi with 
the 3rd joint broad and short. Head broader than the 
thorax, and even slightly broader than the elytra, the 
eyes occupying a large portion of the side and encroaching 
greatly on the under surface ; the hind angles rounded, the 
vertex not gradually narrowed but the neck very abrupt ; 
the surface opaque, very densely and indistinctly, though 
not very finely punctured. Thorax only about half as 
broad as the elytra, longer than broad, the greatest width 
in front of the middle, much narrowed towards the front 
and a good deal towards the base; the surface even, the 
colour yellowish, the punctuation similar to that of the 
head. Elytra distinctly longer than the thorax and rather 
darker in colour, very densely and more roughly and 
distinctly punctured than the head, quite opaque. Hind 
body much pointed towards the extremity, similar in 
colour to the elytra, with the terminal segments blackish, 
densely punctured, and with a short subsquamose golden 
pubescence. Legs pale yellow. 

Tapajos; nine individuals, which show me no external 
sexual distinctions.

This species is excessively closely allied to /. boops, 
but it is slightly more elongate; it has the elytra and 
metasternum infuscate, and the head also is more obscure 
in colour, and differs a little from that of EF. boops in its 
form, it being rather longer in proportion to its breadth, 
so that the eyes do not occupy so large a portion of the

castaneo-testaceus, ely tris fusco- nigrosignatis : crebre for- 
titer punctatus; capite elongato, vertice angusto. Long. 
corp. 24 lin. 

Antenne yellow, rather longer than the head, a little 

thickened towards the extr emity ; 3rd joint much narrower 
but almost longer than 2nd; 4th and Sth joints slender, 
nearly equal to one another, each rather longer than 
3rd; 8—10 bead-like, scarcely broader than long; 11th 
rather broader, and a good deal longer than 10th, 
ending in a seta-like spine. Mandibles reddish, very 
elongate and slender, each with two teeth, of which 
the upper one is very long. Labrum with two sharp, 
stout, triangular, approximate teeth in the middle, and on 
each side these with a smaller sharp projection. Head 
longer than broad, reddish, gradually narrowed from the 
eyes to the vertex, densely punctured ; the punctures rough 
and asperate, except on the front part. Thorax elongate 
and narrow, only half as broad as the elytra, twice as long 
as broad; its greatest width about the middle, thence a 
good deal narrowed towards the front and slightly towards 
the base, dull, reddish in colour, densely punctured. Elytra 
only slightly ‘longer than thorax, yellowish, but with four 
large longitudinal marks towards the extremity (often 
more or less confluent), leaving a basal fascia pale, which, 
however, is subinterrupted in the middle by the extension 
forwards of the dark markings; densely and roughly 
punctured. Hind body elongate, slender and _ greatly 
pointed, obscure yellowish; the basal segments rather 
coarsely and asperately punctured, the apical ones very 
finely and indistinctly. Legs pale yellow; under surface 
chestnut-yellow, coarsely punctured. 

Tapajos ; eleven individuals. 

On dissecting one of these specimens I find it to be a 
male, though there are no external characters to indicate 
this, and the «deagus is small and inconspicuous. The 
black marks on the elytra vary a good deal in their 
extent.

testaceus, elytris fuscis, basi testaceis ; “dense punctatus, 


Staphylinide of the Amazon Valley. 277 


opacus; capite elongato, vertice angusto; thorace medio 
longitudinaliter carinato. Long. corp. 2} lin. 


Antenne yellow, about as long as head ; Ist joint much 
stouter and longer than the following ones, as long as the 
three following joints together ; the two or three penul- 
timate joints distinctly transverse. Mandibles very long 
and slender, the upper of the two teeth in the middle very 
long. Labrum with two widely-separate sharp teeth in 
the middle, and sinuate and emarginate between them ; 
lateral teeth indistinct. Head reddish, gradually narrowed 
from the eyes to the vertex ; convex in the middle, so as 
to give an appearance of two obscure anteriorly divergent 
grooves ; the surface dull, densely and intricately punctured, 
with the interstices extremely fine. Thorax elongate and 
narrow, hardly half so broad as the elytra, quite twice as 
long as broad; the greatest width in the middle, thence a 
good deal narrowed towards the front and slightly towards 
the base, pale reddish-yellow, closely but indistinctly 
punctured, dull; along the middle with a broad longi- 
tudinal elevation, and depressed on either side of this. 
Elytra about as long as the thorax, blackish, with the 
basal portion pale yellow, densely and roughly but not 
coarsely punctured. Hind body elongate and narrow, 
very pointed, yellowish, with the extremity darker, and on 
the side of each segment a small, indistinct, dark mark ; 
the basal segments rather coarsely and roughly punctured. 
Legs pale yellow. 

Tapajos; a single female. 

This species at first sight resembles FE. signatus ex- 
tremely, but is abundantly distinct by the structure of the 
labrum and the carinate thorax. 


5. Echiaster latifrons, n. sp. Latior, piceus, antennis, 
palpis, pedibusque testaceis ; capite lateribus rotundatis, 
vertice angusto ; prothorace elongato, bisulcato; elytris ab- 
domineque fortiter asperato-punctatis. Long. corp. 2? lin. 


Antenne reddish-yellow, rather longer than the head ; 
lst joint very stout, quite as long as the two following 
together; 3rd joint more slender than 2nd; 4th and 5th 
slender, each longer than 2nd, differing little from one 
another; 6th shorter than 5th, 7th shorter than 6th, about 
as long as broad; 8—10 slightly transverse, 11th acumi- 
nate at the extremity. Mandibles reddish. Labrum with 
four sharp approximate teeth in the middle. Head broad, 
quite as broad as the elytra, suborbiculate, with the sides 


278 Mr. D. Sharp’s Contributions to the 


evenly curved behind the prominent eyes towards the 
vertex; the colour is pitchy, the surface quite opaque, 
densely punctured with umbilicate punctures, more indis- 
tinct towards the front; the interstices very fine, the vertex 
in the middle with an obscure, longitudinal impression. 
Thorax only half as broad as the elytra, nearly twice as 
long as broad; the greatest breadth about the middle, 
thence much narrowed towards the front and slightly 
towards the base ; along the middle with two deep, longi- 
tudinal furrows ; the colour similar to that of the head, as 
also the punctuation, but the latter not quite so distinct. 
Elytra quite as long as the thorax, of an obscure fuscous 
colour, with some very indistinct paler spaces at the base, 
densely punctured with a distinct scabrous punctuation. 
Hind body with the basal segments roughly and coarsely 
punctured, the apical ones nearly smooth. Legs pale 
yellow. 

Tapajos; a single individual, of doubtful sex. 

Obs.—In the form of the head this species is interme- 
diate between £. boops and £. signatus ; the individual 
described bears a transverse impression on the middle of 
the head, which I have not mentioned in my description, 
as I think it is the result of accident. 


6. Echiaster mamillatus, u. sp. Infuscato-rufescens, 
elytrorum fascia lata basali, antennis pedibusque testaceis ; 
opacus, dense punctatus; capite angusto, vertice elongato, 
subtus pone orem bimamillato; thorace minus elongato, 
latius bisulcato. Long. corp. 2 lin. 


Rather narrow. Antenne reddish-yellow; 1st joint very 
stout, rather short; 2nd joint stout, bead-like, not longer 
than broad ; 3rd joint small, 5—10 each a little broader than 
its predecessor, 7—10 transverse ; 11th joint rather stout, 
oblique at the apex. Mandibles red, very slender, only 
moderately long. ‘Teeth of labrum short and indistinct. 
Head infuscate-red, about as broad as the thorax ; the sides 
convergent, the vertex forming a neck; the surface densely 
and obscurely punctured, convex between the eyes. Thorax 
longer than broad, much narrower than the elytra, rather 
irregular in form, with a rather obscure elevation along 
the middle, and another still more obscure on each side 
of this; colour and sculpture similar to that of the head. 
Elytra longer than the thorax, blackish at the apex, the 
basal part yellow, this colour forming an angulated fascia, 
which occupies nearly half of the elytra; densely asperately 


Staphylinide of the Amazon Valley. 279 


punctured. Hind body much pointed towards the extre- 
mity, the basal segments densely, moderately coarsely, the 
apical ones very finely punctured. Legs pale yellow. 
Front tibiz slightly dilated towards the apex, and dis- 
tinctly bisinuate externally. On the underside of the head, 
at the base of the mouth, are two peculiar fine tubercles. 

Tapajos ; five specimens. 

Obs.—This species varies much in colour, some indi- 
viduals being nearly black, and others reddish or yellow. 

I have dissected the terminal segments of one of these 
specimens, with the hope of ascertaining it to be a male; 
but I am unable to say positively whether this is the case 
or not; for though I have found what may possibly be the 
edeagus, yet it is so small and insignificant that I am by 
no means sure it may not be merely a portion of some 
dried internal tissue ;—this although I have examined it 
with a very high power. 


7. Echiaster muticus, n. sp.? Infuscato-rufescens, ely- 
trorum fascia basali, antennis pedibusque testaceis; opacus, 
dense punctatus ; capite angusto, vertice elongato, subtus 
mutico ; thorace minus elongato, latius bisulcato. Long. 
corp. 2 lin. 

Tapajos; two individuals. 

Obs.—These two specimens present no difference from 
E. mamillatus, except the absence of the tubercles on the 
underside of the head; it is probable that this may be 
merely a sexual character, the /. muticus being only the 
other sex of £. mamillatus, in which case the species may 
bear the name EF. mamillatus. 


8. Echiaster tibialis, n. sp. Rufus, opacus, dense 
punctatus, pedibus testaceis; capite elongato, postice 
angustato; thorace minus elongato, latius bisulcato ; 
tibiis anterioribus extus dilatatis. Long. corp. 1? lin. 


Antenne red, stout, as long as the head; joints 5—10 
each transverse, and each slightly broader than its pre- 
decessor; 11th joint short. Mandibles very slender, 
rather short. Labrum distinctly quadridentate. Head 
elongate, the sides narrowed, but not rounded from the 
eyes to the neck; the surface elevated in the middle, 
densely and obscurely punctured, quite dull, reddish. 
Thorax much narrower than the elytra, rather longer 
than broad, the sides almost rounded; the greatest width 


280 Mr. D. si: Contributions to the 


about the middle, thence much narrowed to the front, and 
a little towards the base, with a broad, ill-defined, longi- 
tudinal impression along each side of the middle; red, 
punctuation dense and obscure. Elytra much longer 
than the thorax, and slightly paler in colour, densely 
and indistictly punctured. Hind body quite dull, densely 
punctured, and with a very fine and short, depressed 
golden pubescence; 6th segment very elongate. Legs 
pale yellow; anterior tibiz flattened, so that seen on one 
face they appear very broad; their tarsi with the basal 
joint broad, each joint following a little narrower than its 
predecessor. 

Tapajos; three individuals. 

Obs.—These three individuals all have the hind margin 
of the ventral plate of the 6th segment of the hind 
body distinctly emarginate in the middle, and I suppose 
them all to be males; the 7th segment is entirely 
retracted, except in one specimen, in which its hind 
margin is exposed, and this is emarginate beneath, like 
the 6th segment. 


9. Echiaster Batesi, n. sp. Testaceus, dense punc- 
tatus, opacus, abdominis apice fuscescente; capite sat 
elongato, lateribus curvatis, vertice angusto; thorace minus 
elongato, profunde bisulcato. Long. corp. 1% lin. 


Antenne yellow, short, quite as long as the head; Ist 
joint rather short, very stout; 2nd almost orbicular ; 
3, 4, 5 small, subequal to one another; 6—10 each a little 
broader than its predecessor, 9 and 10 distinctly trans- 
verse, 11th moderately long. Mandibles very slender, 
rather short. Labrum very indistinctly toothed. Head 
rather long, the sides gradually narrowed in a rounded 
curve to the narrow vertex, which is not prolonged into 
a neck, red, densely and very indistinctly punctured, 
elevated about the middle. ‘Thorax a good deal narrower 
than the elytra, and almost as broad as the head; rather 
longer than broad, almost rounded at the sides; the 
greatest breadth in front of the middle, thence much 
narrowed towards the front, and distinctly towards the 
base, deeply longitudinally impressed on each side of the 
middle, yellow, quite dull, punctuation very indistinct. 
Elytra rather longer than the thorax, closely and indis- 
tinctly punctured. Hind body densely and indistinctly 
punctured, obscurer in colour towards the extremity. 


Staphylinide of the Amazon Valley. 281 


Legs pale yellow; front tibiae short, distinctly dilated 
towards the extremity; their tarsi short and slender. 
Tapajos; a single individual, of doubtful sex. 
Obs.—The different shape of the head, more slender 
antenn, and the differently-formed front tibie and tarsi, 
readily distinguish this species from F. tibialis ; the indi- 
vidual described is perhaps somewhat immature. 


10. Echiaster scissus, nu. sp. Testaceus, dense punc- 
tatus, opacus, elytrorum apice medio, abdominisque apice 
fuscescentibus ; capite lateribus curvatis, oculis minoribus; 
prothorace lato, suborbiculato, profunde bisulcato. Long. 
corp. (vix extenso) 13 lin. 


Antenne rather slender; Ist joint stout and short, 2nd 
stout, 3rd and 4th very small, 6—10 each a little broader 
than its predecessor, 9 and 10 distinctly transverse, 11th 
rather short and stout. Head slightly broader than thorax, 
a good deal narrower than the elytra; the eyes small, the 
sides behind the eyes greatly rounded; the neck very 
slender, the middle of the surface much elevated, so that 
the vertical portion appears much depressed ; yellow in 
colour, quite dull, densely and indistinctly punctured. 
Thorax short, about as long as broad, greatly narrower 
than the elytra, rounded at the sides, with two deep longi- 
tudinal impressions, so as to make it appear tricarinate, 
densely and indistinctly punctured, quite dull. Elytra 
much longer than the thorax, rather broad, yellow, with 
an infuscate patch in the middle at the extremity, densely 
punctured, quite dull. Hind body rather broad, the basal 
segments rather coarsely punctured, the 6th segment 
conical. Legs pale yellow; front tibize moderately broad, 
slightly sinuate. 

Tapajos; a single specimen. 

Obs.—The small eyes readily distinguish this species 
from all the others here described. 


LINDUS (nov. gen. Pederinorum). 


Palpi maxillares articulo tertio magno, subsecuriforml, 
articulo quarto occulto. 

Mandibule perelongate, tenues, valde curvate, eden- 
tatee. 

Tarsi anteriores fortiter dilatati, posteriore articulo 
quarto simplice.

natum. 

Genus perdistinctum, habitu Pinophilinorum, a quibus 
palporum maxillarium articulo 4° condito, et prothorace 
post coxas membranaceo differt. 


Labrum transverse, with the horny part excessively 
short, and with two stout triangular teeth in the middle ; 
from the outside of the teeth proceeds a white membrane, 
which extends all round the exposed part of the labrum, 
and much increases its size. Mandibles very slender, long, 
pointed and curved, and without any trace of teeth. 
First joint of maxillary palpi much shorter than the others, 
longer than broad; 2nd joint rather slender, more than 
twice as long as the Ist joint; 3rd joint longer than 2nd, 
much dilated, especially on the inner side, the extremity 
rather truncate; 4th joint quite invisible. Ligula broad 
in front and emarginate, so as to be in fact bilobed ; para- 
glossee very distinct and greatly developed, extending a 
good deal beyond the ligula, and distinctly beyond the 
base of the 2nd joint of labial palpi. First joint of labial 
palpi concealed in my preparation by the ligula and para- 
glosse ; 2nd joint cylindrical, quite twice as long as broad ; 
3rd joint not much more than half as broad as 2nd, about 
twice as long as broad. Antenne rather stout, not 
thickened towards the extremity. Head short and trans- 
verse, with a moderately broad neck. Thorax transversely 
quadrate, with the base rounded, the side pieces broad 
throughout, and with a long projection near the hinder 
part; membranous under the coxe; the coxal cavities thus 
forming two rather long oblique openings, which are con- 
fluent in their hinder part. Mesosternum forming chiefly 
a horny neck, only forming at the base of the middle 
coxze a short angular projection. Middle coxal cavities 
large and deep, confluent. Hind body subcylindrical, only 
the basal segment margined, terminated in two stout, 
pointed, rigid styles. Wings present. Front tarsi with 
the four basal jomts forming a broad patella; 5th joint 
slender and rather long. Legs moderately long and 
slender; 1st joint of hind tarsi a little longer than 2nd, 
4th not at all lobed. 

The curious insect for which I have established this 
genus has the hind body formed almost as in Gdichirus, 
and gives one, from its facies, the idea of a member of the 
Pinophilini rather than the Pederini; nevertheless its syste- 


Staphylinide of the Amazon Valley. 283 


matic position at present is in the Pederini, in the neigh- 
bourhood of Lithocharis ; but I have a strong impression 
that it will ultimately prove to be one of the steps of a 
transition to the Pinophilini. 


1. Lindus religans, n. sp. Piceus, nitidus, subparal- 
lelus, antennis, pedibus, palpisque testaceis, elytris fortiter 
seriatim punctatis; abdomine parcius pubescente, crebre 
fortiter, profundeque punctato. Long. corp. 3—3 lin. 


Antenne reddish, rather shorter than head and thorax ; 
1st joint elongate, rather longer than 2nd and 3rd together ; 
3rd joint long, a good deal longer than 2nd, 5—10 each 
a little shorter, but scarcely broader than its predecessor, 
10th about as long as broad; 11th joint short, with a 
slender spine or seta at its apex. Head short and broad, 
slightly narrower than the thorax; eyes large and promi- 
nent, separated by a narrow space only from the hind 
margin, with some coarse punctures at the sides and 
vertex, which are wanting along the middle. Thorax 
transverse, a little narrower than the elytra, nearly trun- 
cate in front, the front angles but little rounded, the base 
and hind angles rounded, the sides nearly straight and 
not narrowed behind; on either side of the middle is an 
irregular, longitudinal series or patch of rather coarse 
punctures, and between these and the sides are other 
scattered, pretty numerous punctures. Scutellum small, 
impunctate. Elytra longer than the thorax, quadrate, 
their extremity emarginate, depressed on either side of 
the finely-elevated suture; in the depression a series of 
rather coarse punctures, and outside this with several 
other series of coarse, deep punctures. Hind body stout ; 
the basal segment margined at the sides, the others with- 
out margins, and each slightly narrower at the base than 
the extremity, very coarsely, closely and deeply punctured ; 
the 6th and 7th segments more sparingly and more finely 
than the basal ones; hind margin of upper plate of 7th 
segment angulate in the middle, and spinous at each side ; 
the connecting membranes of the segments coriaceous, as 
in the Pinophilini. Legs yellow. 

In the male the hind margin of the ventral plate of the 
6th segment of the hind body is slightly emarginate at the 
extremity, and is polished and depressed in front of this 
emargination, and the 7th segment has a large notch or 
excision in the same place. 


284 Mr. D. Se Contributions to the 


Tapajos; four specimens of this interesting species were 
brought back by Mr. Bates, one of which, however, I have 
destroyed by an unfortunate accident during examination. 


PADERUS. 


The species of this very widely-distributed genus brought 
from the Amazons are seven in number; they show 
nothing remarkable, their colour and appearance being 
very similar to our European species; they all have the 
mandibles with a simple bidentate tooth in the middle. 
Although scarcely a score of species of Pederus have 
been as yet described from South America and Mexico, 
the species are really numerous there; the more remark- 
able of the South American forms of the genus, such as 
P. rutilicornis and P. ferus, appear to be unrepresented 
in the Amazons. 

The species of the genus require careful study, and 
some of them have already given rise to much discussion ; 
the structure of the edeagus has been hitherto neglected ; 
but when it is considered, it will, I have no doubt, be 
found to greatly facilitate the recognition and discrimina- 
tion of the species. 


1. Pederus solidus, n. sp.  Robustus, alatus, niger, 
elytris thorace paulo longioribus, cyaneis; abdomine seg- 
mentis quatuor primis, thorace, mesosternoque rufis, 
pedum basi antennarumque basi et apice testaceis, his 
medio infuseatis. Long. corp. 5—5} lin. 


Antenne 12 lin. in length, 3 basal joints yellow, the 
next 6 strongly infuscate, the 10th infuscate-yellow, the 
last joint yellow. Palpi yellow, terminal joint infuscate 
at the apex ; mandibles red. Head black, with the neck 
red, broad, a little broader than the thorax, rather sparingly 
and finely punctured ; the punctures wanting towards the 
middle. Thorax bright red, longer than broad, about 
Z lin. long and scarcely ? lin. broad, sparingly and finely 
punctured, with a broad impunctate space along the 
middle, the punctures bearing fine black hairs. Scutellum 
red, elytra blue, parallel, rather longer than thorax, from 
apex of scutellum to extremity of suture being quite { lin. ; 
their common width also about § lin., rather finely and 
moderately closely punctured. Legs rather long ; the cox 
and base of femora yellow, apical third of femora and the 


Staphylinide of the Amazon Valley. 285 


tibiz nearly black; the tarsi strongly infuscate. The 
central notch of labrum shallow, but rather broad. 

The notch on the ventral plate of the 7th segment of 
the hind body in the male is very deep and parallel-sided. 
In the female the extremity of the same plate forms a 
large triangle, and on each side of this at the base is a 
stout, very short tooth. 

Ega and Tapajos ; several individuals. 

This species.is allied to P. equinoctialis, Er., to judge 
from description. I have several closely-allied South 
American species, but fail to ascertain without doubt 
which of them is Erichson’s species. 


2. Pederus tridens, n. sp. Angustulus, niger, elytris 
humeris angustatis, thorace fere brevioribus, cyaneis; 
abdominis segmentis quatuor primis, thorace, mesosterno, 
mandibulisque rufis; palpis, pedum basi, antennarum basi 
et apice testaceis, his medio fuscis; elytris crebre fortiter 
ruguloso-punctatis. Long. corp. 43 lin. 


Antenne slender, 1 lin. in length, 3 basal joints yellow, 
the 3 apical ones reddish, the middle ones deeply infuscate. 
Palpi yellow, apical joint obscurely infuscate at apex; 
mandibles and labrum reddish, the latter with the central 
excision very small. Head black, with the neck reddish, 
rather elongate, sparingly and finely punctured, the 
punctures wanting on the middle. Thorax red, not quite 
Z lin. in length, and not lin. in width, a good deal nar- 
rowed behind ; the surface shining and almost impunctate. 
Elytra narrow, narrower at shoulders, their greatest 
length about that of the thorax, bluish-green ; coarsely and 
rather deeply but irregularly punctured, so that the in- 
terstices are rugulose. Four basal segments of hind body 
red, the two apical ones blackish. Mesosternum and 
scutellum red. Legs long and slender, the coxze and base 
of femora yellow; apex of femora infuscate, the hinder 
much more broadly so than the anterior; tibize and tarsi 
also infuscate. 

In the female the ventral plate of the 7th segment of 
the hind body ends in an elongate pointed central spine 
in the middle, and on either side in a shorter slightly 
curved spine; the narrow tongue-like process, which forms 
the dorsal plate of the 8th segment, is much longer than 
the broader ventral plate. 

Tunantins; a single female.

3. Pederus lingualis, n. sp. Angustulus, niger, elytris 
angustis thoracis latitudine, cyaneis ; abdominis segmentis

palpis, pedum basi, antennarum basi et apice testaceis, his 
medio nigris; elytris fortiter minus crebre punctatis. 
Long. corp. 5 lin. 


This species resembles exactly the P. tridens above 
described, and appears to differ chiefly in the form of the 
labrum, the central notch being larger and much deeper ; 
the elytra also are more sparingly punctured, the punctures 
being less deep and the interstices not so rugulose. 

In the female the structure of the 7th segment of the 
hind body is the same as in P. tridens; but the narrow 
dorsal process of the 8th segment is less elongate than in 
P. tridens, and projects only a little beyond the ventral 
plate. 

Ega; a single female. 


4. Pederus mutans, n. sp. Rufus, elytris viridi- 
cyanescentibus, antennis medio, pedibus basibus exceptis, 
metasterno, abdominisque segmentis duobus ultimis infus- 
catis ; elytris thorace paulo longioribus, humeris distinctis, 
crebre minus fortiter punctatis. Long. corp. 44 lin. 


Antenne 12 lin. in length, yellow, with the five middle 
joints infusecate. Palpi yellow. Labrum with a very 
small notch in the middle and without lateral emargina- 
tion. Head red, rather narrow in proportion to the 
length, finely punctured, the punctures wanting towards 
the middle. Thorax # lin. in length and @ lin. in breadth, 
distinctly narrowed behind, finely and sparingly punc- 
tured, with a space along the middle free from punctures. 
Elytra of a rather faint bluish-green colour, % lin. in 
length, the shoulders distinct and the sides parallel, their 
punctuation rather deep and close, but not coarse. Hind 
body red, with the apical segments infuscate. Legs with 
the cox and basal portion of femora yellow; the front 
femora entirely yellow, the four posterior ones and all the 
tibiz and tarsi strongly infuscate. 

The male has the usual excision on the ventral plate of 
the 7th segment of the hind body. In the female this 
plate ends in the middle in a large sharply-pointed tooth, 
and each outer angle is also produced and acuminate, a 
broad space being left between the central and each lateral 
tooth. 


Stuphylinide of the Amazon Valley. 287 


Tapajos and Para, two $, two @ individuals, 

I have also another female from Para, which has the 
punctuation of the head coarser, and the sides of the cen- 
tral tooth of the 7th abdominal segment more oblique in 
direction, so that the tooth is broader at the base; whether 
this be a distinct species or a mere variety I am unable to 
decide without an examination of more specimens. 


5. Pederus protensus,n.sp. Angustulus, rufus, capite 
piceo, metasterno abdominisque apice fuscis; femoribus 
apice nigricantibus, tibiis, tarsis antennarumque articulis 
4—7 infuscatis ; elytris viridi-cyaneis, parallelis, thorace 
longioribus, crebre fortiter punctatis. Long. corp. 4 lin. 

Antenne 12 lin. in length, slender, yellow, with the 
middle joints a little infuscate. Palpi yellow; mandibles 
red. Head pitchy, shining, rather sparingly and irregularly 
punctured. Thorax shining red, rather longer than 
broad, a good deal narrowed behind, very sparingly punc- 
tured. Scutellum red. LElytra shining bluish-green, 
Z lin. in length, narrow and parallel, rather coarsely and 
deeply punctured, the punctures rather dense. Hind body 
red, with the apical segments pitchy. Mesosternum, coxve 
and femora yellow, the apex of the four hind femora 
blackish; the tibiz and tarsi infuscate-red, the tarsi 
slender. 

The male has the usual deep excision on the ventral 
plate of the 7th segment. In the female this plate ends in 
a broad triangular projection, and each outer angle forms 
a short broad tooth. 

Para; four specimens collected by Mr. Rogers. 

Obs.—This species appears to be closely allied to P. 
mutans, but is rather narrower and more slenderly formed 
and has the head darker. It is readily distinguished in 
the male sex by the structure of the «deagus, which is 
produced at the extremity into a slender beak-like process. 
In the female the teeth of the ventral plate of the 7th 
segment are rather shorter and broader, and so appear less 
acuminate.

with a small notch in the middle; on either side of this a 
little prominent, and outside the prominence slightly 
emarginate. Head dull blackish, with the neck red ; the 
surface finely coriaceous, sparingly and finely punctured. 
Thorax narrow, a good ‘deal longer than broad, scarcely 
narrowed behind, bright red ; finely and sparingly punc- 
tured, with an impunctate space along the middle. Elytra 
parallel, with the shoulders distinct, a little longer than 
the thorax, rather finely, moderately closely punctured, 
bluish or greenish. Hind body red, with the apical seg- 
ments infusecate. Legs yellow; the apex of the hind 
femora distinctly, of the middle ones less distinctly, infus- 
cate. 

In the female the ventral plate ot the 7th segment of the 
hind body is produced, so as to form a projecting triangle 
at the extremity; the apex of this triangle is scarcely 
pointed, the sides do not project in the form of teeth. 

Kga and Tapajos; several individuals. 

This species oreatly resembles our European P. fuscipes, 
but is remarkably easily distinguished therefrom by the 
coriaceous surface of the head; it has also the antennz and 
palpi differently coloured, these beimg clear yellow, and 
the elytra are less closely and distinctly punctured.

Antenne 12 lin. in length, the three basal joints 
reddish, the rest infuscate ; “3rd joint much longer than

at the apex; palpi red, infuscate towards the extremity. 
Head narrow, only about half as broad as the elytra, much 
narrowed behind the eyes, so that the constriction at the 
neck is but little ; it is black in colour, with a blue tinge on 
its upper side ; it is rather closely punctured, except on the 
middle of the hinder half, where the punctures are but 
sparing. Thorax small, g oreatly narrower than the elytra ; 
towards the front it is a ‘eood deal narrowed ; it is red i in 
colour, and distinctly, regularly and rather closely punc-

the middle. LElytra much longer than the thorax, 7 lin. in 
length, dark bluish, rather finely but not densely punc- 
tured. Hind body dull red, with the two apical segments 
black. The coxe are dark red, the femora blackish, with 
the basal part reddish; the tibize and tarsi obscure or in- 
fuscate red. 

The male has a narrow deep excision, the sides of which 
are parallel, on the ventral plate of the 7th segment. 

Carraranen, April, 1874; a single male brought back 
by Dr. Trail. 

Obs.—The form and sculpture of the head and thorax 
render this species very easy to distinguish. 


SuNIUS. 


This genus is one of the most troublesome, in the 
present state of our knowledge of the Staphylinide, to 
any one dealing with a limited fauna, owing to the variety 
of forms included in the genus itself, while at the same 
time a number of closely allied forms have been detached 
as distinct genera. The nineteen species here described 
as new species of the genus possess all, I believe, in 
common the. following characters: terminal joint of 
maxillary palpi minute, anterior coxal cavities closed 
by the junction of the side pieces of the thorax with 
the large horny prosternum, 4th joint of tarsi consisting 
of a membrane embracing the under surface and sides 
of part of the 5th joint. This combination of characters 
is also found, I believe, in the genera Acanthoglossa, 
Stiliderus, Neognathus, Mesumius, Nazeris, Sunides, 
Stilicopsis, Mecognathus and Dibelonetes; but in the 
present state of our knowledge it seems to me that these 
genera can scarcely be maintained as distinct, especially 
while so many heterogeneous forms are still, as I have 
said, included in Sunius. Of the sixteen species here 
described the first six, viz., S. amicus, S. vittatus, S. ser- 
pens, S. ventralis, S. strictus and S. marginatus, have 
quite the facies of our European S. filiformis, and are 
probably structurally very closely allied thereto; while 
the next four, S. brevis, S. modestus, S. crassus and 
S. pictus, must be placed in the section “ Spurii” of 
Erichson, their short, broad form giving them an entirely 
different facies from the S. filiformis group. 8S. confinis

and S. catena have the thorax more narrow and elongate 
than in the preceding species, and appear to afford a con- 
necting link between Stilicopsis and Sunius. The Sunides 
boreaphiloides of Motsch. from Columbia, which is re- 
ferred in the Munich Catalogue to the genus Lithocharis, 
appears to be an insect allied to S. confinis. The next 
two species, S. bidens and S. bispinus are possibly allies 
of the Dibelonetes biplagiatus, Sahl. ; I say ‘ possibly,” 
because no characters are mentioned by Sahlberg which 
can be considered to distinguish his genus from ‘Sunius, 
and I am in great doubt as to which one of several allied 
forms he intended so toname. The two following species, 
viz., S. spinifer and S. celatus, are very possibly but sexual 
forms of one species; they are very remarkable from the 
great development of the two spines of the labrum. 
S. insignis, the last of the species here described, is very 
peculiar on account of the abruptly constricted anterior 
portion of the thorax. From the above remarks it will 
be inferred that Sunius and its allies offer a prominent 
example of that insuperable difficulty in which those 
occupied with descriptive zoology find themselves con- 
stantly involved; for while it is clear that the only idea 
that can be formed of a genus is that of a limited aggre- 
gate of existing species, and consequently that no genus 
can be known till all the existing species of it are known, 
and till whether the characters assigned to it are naturally 
limited or not is known,—while this, I say, is clear, yet we 
are obliged to proceed in our actual descriptions on the 
absurd and “ unthinkable” hypothesis that we know the 
genus before we know the species. I do not think 
naturalists have yet fully recognized this difficulty, but 
certainly until they have recognized it and are prepared to 
deal with it, it will be impossible that zoology can take the 
place it is entitled to as a most charming and important 
educational science. The present method of systematic 
zoology is certainly irreconcileable with a system of syn- 
thetic and inductive science, however well adapted it may 
have been to a period when educated minds were under 
the confusing domination of metaphysical inquiries.

thorax, slender and scarcely thickened towards the apex ; 
2nd joint half as long as Ist; 3rd distinctly longer than 
2nd, slightly longer than 4th; 4—7 scarcely differing 
from one another, 7—10 each very slightly shorter but 
scarcely stouter than the predecessor, 11th one and a half 
times the length of 10th. Head scarcely broader than 
thorax ; eyes rather large and prominent, blackish or 
pitchy, quite dull; punctuation dense, very indistinct, 
consisting of large umbilicated punctures, separated by 
very fine interstices, with a fine pale pubescence and out- 
standing black setze. Thorax about as broad as the elytra, 
a good deal narrowed behind, but broad at the base; 
colour, sculpture and pubescence similar to those of the 
head. Elytra only slightly longer than the thorax, pitchy, 
with a narrow band at the apex yellow; densely punctured, 
with rather fine granular punctures, quite dull. Hind 
body elongate and narrow, only a very little narrower at 
the extremity than at the base, dull, densely and finely 
punctured, with a fine but very distinct ashy pubescence. 
Legs very pale yellow. 

In the male the 6th segment of the hind body has an 
ill-defined channel along the middle, which reaches neither 
the base nor the hind margin; the latter is hardly per- 
ceptibly emarginate, but is furnished in the middle with a 
row of very short, fine black sete ; the hinder part of the 
ventral plate of the next segment bears a rather deep 
excision. 

Tapajos; one male and three female individuals. 

Obs. I.—Rather closely allied to our European 8, 
diversus ; this species is readily distinguished, however, 
therefrom by its duller surface, longer antenne, broader 
thorax and the narrower band of the elytra. 

Obs. I1.—Besides these individuals, I have from the 
same locality two specimens (é and 2) which do not 
appear to me to differ from them in any material respect 
except that of colour. These two individuals are entirely 
of a pale-fulvous colour, and appear at first sight, there- 
fore, very different from the dark individuals above 
described; but I consider them merely a variety of the 
species.

Extremely closely allied to S. amicus, but readily dis- 
tinguished by the colour of the elytra, cach of which has 
the outside occupied by a large black patch, which does 
not quite reach the apex ; the suture also very narrowly 
blackish, the space between these black marks, as well as 
the apex, yellow. It is also rather more slender than 
S. amicus, and the male characters are different. 

In the male the ventral plate of the 6th sezment of the 
hind body has a broad longitudinal impression on the 
middle, its hind margin being quite simple; the hinder 
part of the ventral plate of the next segment bears a 
rather deep excision. 

Tapajos; three males, two females.

Antenne not quite as long as head and thorax, pale 
yellow; 1st joint hardly longer: than 3rd; 3rd much longer 
than 2nd, 4—6 differing little from one another ; 7—10 
each sliehtly shorter and scarcely broader than ‘its pre- 
decessor, 11th distinctly thicker than 10th. Head 
broader than thorax, quite as broad as elytra, yellowish 
in colour, very densely and indistinctly punctured, dull ; 
the punctures very shallow, the interstices very fine; eyes 
large, placed at the middle of the sides. ‘Thorax longer 
than broad, a little narrower than the elytra, almost oval, 
the sides much narrowed behind ; colour and sculpture 
similar to those of the head. LElytra narrow, rather longer 
than the thorax; rather paler in colour than the other 
parts, each with a dark oval spot on the middle nearer to 
the apex than to the base ; rather coarsely but indistinctly 
and not densely punctured, not so dull as the other parts. 
Hind body elongate, very narrow at the base, broader 
towards the extremity, yellowish; the 6th segment blackish 
except at the extremity, quite dull, densely and finely 
punctured, with a very fine dense pubescence. Legs very 
yale. 

The male has a rather deep excision at the extremity of 
the ventral plate of the 7th segment of the hind body. 

Tapajos; numerous examples.

About the size of S. angustatus, but rather more slender. 
Antennz long and slender, as long as head and thorax, 
scarcely thickened towards the apex, very pale yellow; 
3rd joint much longer than 2nd. Labrum very short, with 
a slight notch in the middle, it is a little angular on each 
side of the notch. Head considerably broader than the 
thorax, about as broad as the elytra; eyes large, and placed 
at the middle of the sides, remote from the antennz; the 
surface densely but indistinctly punctured, with the punc- 
tures large and ocellated, the interstices extremely fine, 
Thorax rather small, more than half as broad as the elytra, 
longer than broad, a good deal narrowed towards the base, 
and rounded in front; sculpture similar to that of the head. 
Elytra rather broad, short and convex, a little longer than 
the thorax, yellowish in colour, paler at the apex than at 
the base, on the middle of each an obsolete trace of a 
darker mark; the punctuation sparing at the extremity, 
closer at the base. Hind body convex, narrow at the base, 
a good deal broader towards the extremity, shining but 
for the long, fine pubescence; rather coarsely punctured, 
the punctures consisting of three rows of transversely 
placed punctures on each segment; these rows very dis- 
tinct on the under side, much less distinct on the upper. 
Legs very pale yellow. 

In the male the 6th segment of the hind body has on 
‘the under side a large, impunctate, longitudinal impres- 
sion, and the following segment bears a small notch at the 
extremity. 

Tapajos; a single male. 

Obs.—This species is interesting from the peculiar, 
Qdichirus-like punctuation of the hind body.

Very similar at first sight to S. angustatus. Antenne 
yellow, as long as head and thorax; Ist joint rather stout, 
2nd more slender and a good deal longer than 3rd; 4—7 
slender, 8—10 each a little thicker than its predecessor, 
10th more than twice as long as broad, 11th distinctly 
stouter and a good deal longer than 10th. Mandibles 
elongate, yellow. Head broader than the thorax, about 
as broad as the elytra, blackish, with reticulate punctua- 
tion, which becomes more rugulose on the vertex. Thorax 
small, rather longer than broad, much narrower than the 
elytra; much narrowed towards the base,and more abruptly 
towards the front, blackish, with a coarse, reticulate sculp- 
ture. Elytra broad and short, scarcely longer than the 
thorax, black, with the apical portion pale yellow, the pale 
part slightly broader near the suture than at the sides; 
they are densely, rather coarsely and rugulosely punctured. 
Hind body blackish, with the hind part of the 6th and 
following segment paler: it is rather stout and convex, but a 
good deal narrowed at the base; it is coarsely punctured. 
The legs are rather short, and almost white. 

Rio Purus; a single female, taken by Dr. Trail on the 
13th October, 1874. 

Obs.—This species much resembles our European S. an- 
gustatus, but is slightly larger, the antenne are conside- 
rably longer, the elytra are shorter and more rugulosely 
punctured, and the pale colour does not extend so far 
forwards along the suture; the hind body is more con- 
stricted at the base, and the eyes are a good deal larger.

Antenne slender, quite as long as head and thorax ; the 
10th joint scarcely visibly thicker than the preceding ones, 
and the 11th only very slightly thicker than 10th. Head 
coarsely punctured, and with reticulate sculpture. Thorax 
with reticulate sculpture, of which the meshes are large 
and distinct. Elytra rather longer than the thorax, with 
a coarse and rather distinct punctuation, black, with the 
hind margin yellow, the yellow colour extending much 
farther forwards along the suture than elsewhere. Hind 
body rather coarsely punctured, and with distinct, rather 
coarse pubescence and sete. 


Staphylinide of the Amazon Valley. 295 


Para; a single female captured by Mr. Rogers. 

Obs.—The resemblance of this species to S. angustatus 
is at first extreme ; not only is the general form and out- 
line similar, but the colours of the elytra are similarly 
disposed ; nevertheless, the two species are very different 
when compared. S. marginatus has the antenne very 
much longer, the eyes larger, the thorax more elongate, 
and the sculpture coarser and less dense. S. marginatus 
is closely allied to S. strictus, but has the sculpture coarser, 
less dense, and therefore more distinct; the elytra rather 
longer, and the colours differently disposed, and the in- 
termediate joints of the antenne rather more elongate. 


7. Sunius brevis,n.sp. Brevior, latiusculus, parallelus,

14 lin. 


Antenne pale yellow, rather slender, a little shorter than 
head and thorax ; Ist joint elongate, as long as the three 
following together, 3rd a little longer than 2nd; the joints 
from 4—10 slightly thickened, the 10th being distinctly 
broader and shorter than the 4th, but not so broad as long; 
11th joint rather stout, and a good deal longer than 10th. 
Labrum large, oblique on each side, so as to be prominent 
in the middle, the most projecting part with a slight notch. 
Mandibles moderately long; the left with one, the right 
with two teeth. Head broad, quite as broad as the elytra; 
the eyes large and prominent, placed in the middle of the 
sides, the vertex appearing emarginate in front of the neck ; 
the hind angles about right angles, and a little rounded ; 
the surface dull, densely punctured with large but indis- 
tinct punctures, the interstices of which are extremely fine. 
Thorax about as broad as the elytra, distinctly transverse ; 
the front rounded, the sides a little narrowed behind; the 
surface densely punctured, in a similar manner to the 
head. Elytra yellow, paler than the head and thorax; the 
side of each with an ill-defined spot, distinctly longer than 
the thorax, rather closely punctured. Hind body broad 
and short, very finely punctured. Legs pale yellow, rather 
short. 

In the male the hind margin of the ventral plate of the 
6th segment of the hind body is slightly emarginate on

each side of the middle; that of the 7th segment is broadly 
emarginate.

8. Sunius modestus, n. sp. Brevior, latiusculus, paral- 
lelus, testaceus, capite piceo-rufo, thorace rufescente ; dense 
punctatus, subopacus; capite subquadrato; thorace trans- 
verso. Long. corp. 14 lin. 

This species is extremely close to S. brevis, but the 
head and thorax are not quite so broad; the elytra are 
without lateral mark; the head is darker in colour, and its 
punctuation is more conspicuous, and joints 3—10 of the 
antenne are not quite so elongate. These differences are 
but slight however. 

In the male the hind margin of the 7th segment is 
broadly emarginate; and the 6th segment, instead of being 
emarginate on either side as in S. brevis, has a single 
broad, rather deep emargination, extending from side to 
side, like that of the 7th segment. 

Tapajos; one male and one female. 


9. Sunius crassus, n. sp. Brevior, latiusculus, paral-

Iixtremely Blacally allied to S. brevis, but not quite so 
dull; the head and thorax rather more distinctly punc- 
tured, the thorax not quite so transverse; the elytra more 
sparingly punctured and distinctly shining, and without 
lateral mark, and the antennz a little shorter. Even more 
closely allied to S. modestus, but with the head rather 
broader and paler in colour, and the elytra more distinctly 
less closely punctured.

than its predecessor, 7—9 differing little from one 
another, 10th slightly stouter and shorter than 9th, small, 
about as long as broad; 11th joint a good deal longer and 
distinctly stouter than 10th. Head large, subquadrate ; 
the eyes prominent and rather large ; the vertex straight, 
but emarginate at the neck; the hind angles but shghtly 
rounded, reddish, densely punctured, the punctures dis- 
tinct, and each umbilicate, the interstices extremely fine. 
Thorax scarcely narrower than the head, and very slightly 
narrower than the elytra, nearly as long as broad; the front 
rounded, the sides slightly conver oent behind; the colour 
and sculpture similar to those of the head, but the latter 
rather finer and less distinct. Elytra rather longer than 
the thorax, quadrate, rather finely and closely punctured; 
a large spot on the side of each black, and the suture also 
blackish, but with this colour not reaching to the scu- 
tellum. Hind body broad and short, densely, finely and 
indistinctly punctured; the basal segments reddish, the 
5th infuscate, the 6th pale yellow. Legs pale yellow, 
rather short. 

Ega; a single female. 

Obs.—This species is closely allied to S. brevis, but is 
larger, and its thorax is less transverse ; I have not been 
able to examine satisfactorily the mandibles and labrum 
of the only individual I possess, but from what I can see of 
them, I have little doubt they are very similar to those of 
S. brevis.

each about as long as broad, and just a little broader than 
its predecessor; 11th distinctly stouter than the 10th. 
Labrum with two short but distinct denticles in the 
middle. Mandibles moderately long and slender, their 
teeth very indistinct. Head rather long and narrow, dis- 
tinctly broader than thorax, and narrower than elytra; the 
eyes placed in the middle of the sides, convex and pro- 
minent, the hind angles rounded; reddish in colour,

densely but not very distinctly punctured, the interstices 
extremely fine. ‘Thorax rather small, a little longer than 
broad, much narrower than the elytra; its greatest width 
in front of the middle, thence much narrowed towards the 
front, and slightly towards the base; colour and sculpture 
similar to those of the head. Elytra rather elongate, 
much longer than the thorax, a little narrowed towards 
the shoulders, yellow, distinctly and moderately closely 
and finely punctured. Hind body broad and rather short, 
tawny in colour, dull, very finely punctured and pubescent. 
Legs pale yellow, moderately long.

corp. 14 lin. 


Antenne pale yellow, moderately slender; 1st joint as 
long as the three following together ; joints 6—10 each 
slightly broader than its predecessor, the 10th almost 
transverse, 11th rather stouter than 10th. Labrum large, 
with two very approximate denticles in the middle, and 
with an extremely small one on either side of these. Head 
large, broader than the thorax, and quite as broad as the 
elytra, the hind angles quite rounded, the eyes prominent; 
reddish in colour, densely punctured, with the interstices 
very fine. Thorax a good deal narrower than the elytra, 
rather longer than broad; its greatest breadth in front of 
the middle, thence much narrowed towards the front, and 
distinctly towards the base; reddish, quite dull, densely 
punctured. Elytra quite as long as the thorax, quadrate, 
yellow, distinctly, moderately closely punctured, a little 
shining. Hind body broad, rounded at the sides, yellowish, 
densely and finely punctured. Legs pale yellow. 

In the male the hind margin of the ventral plate of the 
6th segment of the hind body is broadly but shallowly 
emarginate ; the 7th segment is concealed in the example 
described. 

Ega; a single male. 

Obs.— This species is readily distinguished from 
S. confinis by its broader form and shorter elytra. I have 
been unable to keep open the mandibles for proper exami- 
nation, but I think they are longer and have the teeth

more distinct than in S. confinis. The insect greatly 
suggests by its form and colour a Boreaphilus, and makes 
a great approach to Stilicopsis paradoxus, Sachse.

thorace suborbiculato. Long. corp. 13 lin. 


Antenne slender, pale yellow, shorter than head and 
thorax, not thickened towards the extremity; Ist joint 
elongate, about as long as the three following together ; 
2nd joint rather slender, 3rd distinctly longer than 2nd, 
4—10 each slightly shorter than its predecessor; 11th 
longer, but scarcely broader, than 10th, oblique at the 
extremity. Mandibles elongate and slender, the left one 
with two teeth, of which the upper one iselongate. Labrum 
much produced towards the front in the middle, the pro- 
minent part terminating in two distinct teeth. Head 
much larger than thorax, and even broader than the 
elytra; the eyes large and convex, placed in the middle of 
the sides, the hind angles not much rounded, the vertex 
emarginate in front of the neck; reddish in colour, closely 
finely and not very distinctly punctured, with extremely 
fine interstices, the punctuation becoming obsolete in the 
middle towards the vertex, so that in front of the emar- 
gination it 1s represented only by some fine granules. 
Thorax small, much narrower than the elytra, not longer 
than broad; the greatest width in front of the middle, 
thence much narrowed towards the front, and distinctly 
towards the base; reddish in colour, densely punctured, 
with very fine interstices. Elytra rather broad and short, 
a little longer than the thorax, infuscate, so as to approach 
blackish in colour; the extreme base obscurely reddish,

Antenne elongate and slender, almost geniculate, not 
thickened towards the extremity; Ist joint elongate, as 
long as the three following together; 2nd joint rather 
long, 3rd more slender than, but about as long as 2nd, 
5—10 each a little shorter than its predecessor, 11th rather 
long, slightly stouter than, and twice as long as the 10th, 
Mandibles elongate, the left one with two teeth, of which 
the upper one is clongate, the right one with three rather 
large teeth. Labrum large, the middle prominent, and 
with two rather long and slender teeth, and on each side 
of these with a small obscure one. Maxillary palpi pale 
yellow; 2nd and 3rd joints elongate and slender, the 3rd 
being about four times as long as broad. Head rather 
large, broader than the thorax and quite as broad as the 
elytra, the vertex rounded, the neck narrow, the eyes 
remote from the antennx, the colour pitchy or infuscate 
red; the surface rather coarsely punctured, with the usual 
Sunius punctuation. Thorax a good deal narrower than 
the elytra, rather longer than broad; the greatest width in 
front of the middle, thence abruptly narrowed to the front, 
and a good deal towards the base ; in colour and sculpture 
similar to the head. Elytra quadrate, a little longer than 
the thorax, blackish, with the extremity rather broadly 
pale yellow ; the base reddish, moderately closely, quite 
distinctly punctured, a little shining. Hind body finely 
punctured; the two basal segments reddish, the three fol- 
lowing ones blackish, the extremity yellow. Legs long

head and thorax ; Ist joint elongate and slender, not quite 
so long as the three following together; 2nd joint rather 
long; 3rd joint elongate and very slender, longer than 
2nd; 4—10 each very slender, each slightly shorter than 
its predecessor, even the 10th three times as long as 
broad; 11th slender, but distinctly stouter than the pre- 
ceding ones, rather longer than 10th. Labrum large, 
with two short, obtuse denticles in the middle, forming its 
most prominent part; slightly emarginate on each side of 
these, and thence falling away on either side as an oblique 
sinuation to the lateral angle. Mandibles elongate, ab- 
ruptly curved, stout at the base; the left in the middle 
with a large stout tooth, which is slightly emarginate on 
its inner side; the right one with two rather large teeth, of 
which the upper one is the longer. Head broader than 
the thorax, quite as broad as the elytra; the eyes large, 
and very outstanding in front; the sides behind the eyes 
rounded and narrowed in a curve to the neck, yellowish in 
colour, rather flat; the surface with Swndus punctuation, 
forming rather large meshes, but immediately in front of 
the neck the sculpture obsolete; the underside almost 
impunctate. Thorax a good deal narrower than the elytra, 
the sides in front of the middle much rounded and nar- 
rowed to the neck, only very slightly curved, and narrowed 
from the widest part to the base; its colour and sculpture 
similar to the head. Elytra elongate, one and a half times 
the length of the thorax, yellowish, each with a dark spot 
on the middle, moderately finely and closely punctured. 
Hind body elongate and slender, dull, but only sparingly 
and indistinctly punctured. Legs elongate, very pale. 

In the male the hind margin of the ventral plate of the 
6th segment is broadly but slightly emarginate; the 7th 
has a very large and deep semicircular excision.

than broad. LElytra distinctly longer than the thorax, 
rather coarsely, closely and deeply punctured, marked each 
with an indistinct fuscous spot on the middle, and with a 
common one on the suture, towards the extremity. Hind 
body indistinctly and sparingly punctured, each segment 
with a longitudinal fuscous mark on each side, close to the 
margin, and the 6th with the base transversely marked 
with the same colour. 

_ In the male the hind margin of the ventral plate of the 
6th segment of the hind body is broadly but not deeply 
emarginate; the 7th has a rather broad and moderately 
deep subtriangular excision, the lower angles of which are 
quite rounded. 

Tapajos; a single male. 

Obs.—This species appears at first sight to be very 
closely allied to S. bidens, but when examined is found to 
be very distinct. S. bispinus is much broader, has the 
teeth of the labrum more elongate, the 10th joint of the 
antenne stouter, and the notch of the 7th segment of hind 
body very different in form. 


17. Sunius spinifer, n. sp.  Elongatus, castaneus, 
capite thoraceque plus minusve infuseatis, illo elongato, 
labro spinis duabus elongatis armato ; elytris nitidulis,

perelongatis. Long. corp. 3} lin. 


Antenne very slender and elongate, nearly 13 lin. in 
length, quite filiform; 3rd joint very elongate, abuts as 
long as the basal joint; jomts 4—10 differing from one 
another only in those nearest the apex being a little shorter; 
11th joint elongate, pointed, slightly stouter and but little 
longer than 10th. Labrum large, in the middle with two 
straight, slender, elongate spines, and angulate on each 
side of these. Mandibles extr emely elongate, toothed near 
the base with two teeth, of which the lower is ver y small, 
Head very elongate, the eyes convex, placed rather nearer 
to the antennz than to the vertex, the sides behind the 
eyes narrowed in a gradual curve to the neck; pitchy in 
colour, with the usual Sunzus sculpture, which is rather 
coarse and conspicuous; beneath with moderately coarse 
impressed punctures. ‘Thorax much narrower than the 
elytra, longer than broad, transversely convex; the greatest 
breadth in front of the middle, thence much narrowed 


Staphylinide of the Amazon Valley. 303 


towards the front and slightly towards the base; blackish in 
colour (or reddish if immature), coarsely sculptured in a 
similar manner to the head, the sides towards the front 
appearing serrate. Elytra rather longer than the thorax, 
of a shining castaneous colour, with a dark spot on the 
middle, rather coarsely and deeply but not densely punc- 
tured. Hind body with the segments sericeous and cori- 
aceous at the base, the hind portion of each shining and: 
punctured, the punctures rather obsolete but moderately 
coarse ; beneath entirely with a peculiar silky lustre and 
very obsoletely punctured. Legs yellow; the apex of the 
femora slightly infuscate. 

In the male the ventral plate of the 6th segment is con- 
siderably shorter than the dorsal plate and is a little 
emarginate, and the ventral plate of the following segment 
is broadly but not deeply excised. The wdeagus itself is 
provided at the extremity with a slender elongate ap- 
pendage, which is quite as long as the body of the organ ; 
this appendage is sinuate in the middle, and furnished at 
the apex with an abruptly inflexed additional piece, giving 
its apex the form of a hook. 

EKga ; three individuals,—two males, one female.

macula media fuscé; antennis tenuibus perelongatis. 
Long. corp. 34 lin. 

In the male the edeagus is furnished with an elongate 
and rather broad strap-like appendage, which is shorter 
than the body of the organ, a little constricted in the 
middle and furnished at the extremity with a very small 
abruptly inflexed additional piece. 

Tapajos ; a single male. 

Obs.—The single individual before me seems to me to 
offer no certain character to distinguish it from S. sp7- 
nifer, except the difference in the edeagus; as the form 
and length of the appendage of this organ is quite the 
same in the two males from Ega, I have thought it advi- 
sable to consider the Tapajos individual as indicating a 
different species, though further researches on an addi- 
tional number of specimens will be necessary before this 
can be considered to be certainly established.

Antenne pale yellow, of the ordinary Sunius structure, 
about as long as head and thorax, slender; 3rd joint much 
longer than 2nd, 4—10 each shorter than its predecessor, 
8—10 each slightly less slender than its predecessor, 10th 
longer than br road, 11th rather stouter and a good deal 
longer than 10th. Labrum very large, the middle part 
much produced, and the most projecting part truncate, 
without notch or teeth. Mandibles moderately long, much 
curved ; the left with two, the right with three teeth i in the 
middle. Head shining chestnut in colour, of the usual 
Sunius form, but more » evadually narrowed behind towards 
the slender neck; ; it is only sparingly and indistinctly 
punctured. Thorax narrower than the elytra, of a sin- 
gular, somewhat flask-shaped, form ; the sides of the hinder 
portion rounded, then abruptly need in front of the 
middle to make a slender neck; the middle part is more 
elevated than the sides, so that there is the appearance of 
a longitudinal depression on each side; it is of a brownish 
or chestnut colour and is rather coarsely punctured ; it has 
a narrow impunctate line along the middle, and the lateral 
portions are only indistinctly punctured. Elytra about as 
long as thorax, rather shining, of a chestnut colour, each 
with a darker oblique mark across the middle, and the 
outer angle alittle paler; they are rather deeply, somewhat 
coarsely ‘and closely punctured. Hind body broad, chest- 
nut-yellow, alittle shining; the front portion of the two or 
three basal segments rather distinctly punctured, the rest 
scarcely visibly punctured. Legs very pale yellow; the 
first joint of the hind tarsus about as long as the other four 

together. 

a single female of this extremely remarkable species 
was captured by Dr. Trail on the 5th November, 1874; 
but he has not transmitted to me the exact locality. 


TXNODEMA. 


This genus consists at most of seven or eight described 
species, two only having been known to E richson ; never- 
theless I have described here eighteen species, and have 
quite a dozen others in my collection. The genus appears 


Staphylixide of the Amazon Valley. 305 


to me one of the most characteristic of the South American 
Staphylinide ; it has not yet occurred in Mexico or away 
from the tropical parts of the South American continent, 
and I know of no similar insects in the Old World. The 
species here described show a considerable variation of 
size, form and appearance, though some of them are ex- 
cessively closely allied inter se. They are apparently very 
rare, and I have had great difficulty in making up my 
mind as to whether certain of the forms should be treated 
as species or varieties; it is possible that I may in some 
cases have come to wrong conclusions on this point, 
although I have made a very careful examination in each 
case before coming to a decision.

extremity as at the base, about as long as head and thorax 
(3 lines in length); 3rd joint nearly twice as long as 2nd, 
11th slightly longer than 10th. Head distinctly narrower 
than the thorax, with a large shallow impression on each 
side in front; its surface with the middle and vertical 
portions nearly impunctate, the impressions coarsely 
punctured ; some coarse scattered punctures behind the 
labrum, and a few very coarse rugose punctures on the 
inner side of the hind part of the eye; besides the coarse 
punctures the surface is sparingly sprinkled with some 
minute punctures. Thorax about as long as broad, slightly 
rounded at the sides, dark brassy, shining, sparingly and 
rather finely punctured; the punctures irregularly dis- 
tributed, consisting of two longitudinal patches along the 
middle separated by a broad irregular space, and outside 
these with some punctures towards the sides, the front 
part (behind the eyes) slightly raised and smooth ; besides 
the larger punctures with a few minute punctures, which 
ave most visible about the sides. Scutellum narrow and 
elongate, with a few coarse punctures. Elytra about as 
long as, and scarcely broader than, the thorax, dark brassy, 
with some coarse punctures scattered over them; the hinder 
external angles much rounded, and, as well as the project- 
ing humeral angles, free from punctures. Hind body

presented by only a single female. 

The Staphylinus eneus of Olivier, from Surinam, is 
probably a closely allied species.

similar in colour to the head, with a longitudinal patch of 
punctures on each side the middle, with some other coarse 
punctures at the side about one-third of the length from 
the front, and three or four others behind these, and also 
with some fine punctures scattered sparingly over the 
surface. Scutellum same colour as head and thorax, with 
a few rather coarse punctures. Elytra scarcely longer 
than the thorax, violet, but blue at the base, smooth and 
shining, very sparingly punctured, the punctures becoming 
extremely fine and sparing towards the extremity. Hind

St. Paulo; two individuals, ¢ and ¢. 

Apart from its beautiful colour, this species, though 
clothed with long black sets, is remarkable for the very 
scanty pubescence of the upper surface.

coarsely punctured, only a narrow transverse space between 
the eyes being impunctate; the punctures are umbilicate, 
each bears a fine pale hair. Thorax nearly as long as 
broad (about 1 lin. broad, and +3 long); it is a little 
rounded at the sides, and slightly narrowed behind, 
similar in colour to the head; the surface is rather closely 
but unequally covered with punctures, the punctures 
wanting on a space on each side near the front angles, 
also on a very small longitudinal space in front of the 
base in the middle, and more sparing about the margins 
than they are on the disc; the punctures are of unequal 
sizes, the larger ones being umbilicate. Scutellum brassy, 
punctured. Elytra quite 14 ln. in length, shining 
metallic, the basal part similar in colour to the head and 
thorax, the apical part blue; they are sparingly punctured, 
the punctures are all fine, those at the base being coarser

rounded at the sides, similar in colour to the head, very 
shining, coarsely punctured, the punctures irregularly 
distributed, wanting on a space near the front angles ; two 
elongate patches of punctures along the middle separated

and slightly narrowed behind. Scutellum with a few fine 
punctures. Elytra 1 ln. in length, Hind body nearly 
concolorous at the extremity. 

Ega; a single male. 

This may possibly prove to be only an individual varia- 
tion of T'enodema lenta; it differs only from it in being 
rather smaller, and having the front parts rather narrower, 
the thorax being a little less rounded at the sides, rather 
more coarsely punctured along the middle, the punctua- 
tion of the hind body rather less, and the legs a little 
shorter. 


6. Tenodema quadrata, n. sp. Nigra, nitida, capite,

Antenne about 14 lin. in length, the two basal joints 
yellow, the intermediate ones nearly black, the apical joint 
pitchy yellow ; 3rd joint about one and a half times as long 
as 2nd. Head small, rather closely punctured, a space 
in front of the vertex impunctate, the punctures on the 
front part forming a patch in the middle and a patch on 
each side, but the three patches only a little separate; 
vertex rather finely punctured. Thorax not quite so long 
as broad, nearly % lin. in length, a little rounded at the 
sides, not narrowed behind, shining, coarsely punctured, 
the punctures more sparing towards the margins, and

wanting on a space near the front angle. Scutellum 
finely but rather closely punctured. Elytra about 1 line 
in length and rather broader than long, brassy-green, 
shading into bluish at the sides and extremity, very 
shining, finely and sparingly punctured, the punctures 
almost wanting towards the extremity, and closer together 
along the suture, especially at the base. Hind body quite 
black. Legs rather short. 

Kga; a single female. 

This species is again very closely allied to 7. lenta, but 
is shorter but not narrower; the elytra are distinctly more 
quadrate, and the legs a little shorter. 


7. Tenodema tarsalis, n. sp. Nigra, nitida, capite, 
thorace, elytrisque viridi-zneis; antennarum basi, palpis, 
tarsisque anterioribus testaceis; capite thoraceque fortiter,

Antennz slender, just over a line in length, black, with 
the two basal joints yellow, the apical joint nearly black; 
the 3rd joint one and a half times as long as the 2nd. 
Head small, above shining green, the front part coarsely 
punctured, not so closely along the middle as in the lateral 
depressions; a space in front of the vertex impunctate, the 
vertex punctured, but the punctures almost absent from 
its middle. Thorax about as long as broad, a little 
rounded at the sides, scarcely at all narrowed behind, 
shining, brassy-green, coarsely punctured, the punctures 
sparing towards the margins; a space near the front angles 
quite impunctate. Elytra about { lin. in length, scarcely 
so broad as long, greenish-brassy, more bluish at the sides 
and extremity, finely and sparingly punctured. Hind 
body entirely black; legs rather short. 

Ega; a single female. 

I am doubtful whether this will prove a distinct species 
from J. guadrata or not; it is a little smaller than 
T. quadrata, the head, thorax, and especially the elytra, 
are a little narrower; the antenne are a little shorter and 
the front tarsi rather less dilated.

bearing a few fine pale hairs; transverse space between the 
eyes smooth and shining. Thorax about 2 lin in length, 
and about the same in breadth, slightly rounded at the 
sides, and slightly narrowed behind; the disc flattened and 
coarsely and densely punctured, the margins with only a 
few scattered punctures, this free space being largest on 
the front near the angles; the colour is shining bluish- 
green, like that of the head. Elytra about as long as the 
thorax, rather broader than long, shining blue, rather 
finely and sparingly punctured; the punctures rather 
coarser and closer at the suture behind the scutellum than 
elsewhere, becoming finer towards the extremity and sides, 
so as to be wanting at the hind angles. Hind body black 
and shining, sparingly punctured, the hind parts of the 
segments impunctate, the 6th and 7th only very finely 
punctured, the outstanding black sets well marked. Legs 
short and stout, black, with the front tarsi pitchy above, 
pale beneath; under face of hind body more coarsely

Ega; a single female. 

This species, though it greatly resembles, at first sight, 
T. tarsalis and the allied species, may be readily distin- 
guished by the dense and regular sculpture of the thorax, 
the punctures being all large and crowded together on the 
middle, instead of being of unequal sizes and unevenly 
distributed.

Antenne about 2 lin. in length, scarcely thickened to- 
wards the extremity, pitchy, with the two basal joints 
yellow behind ; 3rd joint much shorter than Ist, about one 
and a half times as long as 2nd. Palpi pitchy yellow, 
with the upper margin of the last joint yellow; mandibles 
pitchy, reddish at the apex. Head coarsely and densely 
punctured and clothed with a pale pubescence, a trans- 
verse space in front of the vertex smooth and shining. 
Thorax 1 lin. long and about § broad, very densely punc- 
tured, a small space on each side in front and the hind 
margin free (in a fresh specimen. probably densely clothed 
with ashy pubescence). Elytra fully 11 lin. in length, 
densely punctured; the suture (except at the base) has a 
very narrow space free from punctures, and the hind 
margin is also free, but the punctures almost completely 
cover the extreme base and front angles (in fresh speci- 
mens the punctured parts probably covered with a dense 
pale-ashy pubescence). Hind body black; the segments 
punctured and pubescent, except on their apical portions ; 
8th segment and hind margin of 7th reddish. Legs pitchy, 
with the femora red. 

In the male the hind margin of the ventral plate of the 
7th segment is a little emarginate at the extremity. 

Ega ; a single male individual. 

Very closely allied to 7’. cinerea, but narrower, with 
the thighs clear red, the front parts on the upper surface 
quite blue, and the thorax and elytra more evenly covered 
with punctures. The male has the edeagus considerably 
longer than +n cinerea and rounded at the extremity, 
whereas this is acuminate in ctnerea. The single in- 
dividual, which is all I possess for comparison, has the 
upper surface very rubbed, but I have no doubt, from the 
few hairs that remain, that in the fresh state the pubes- 
cence is very similar to that of 7’. cinered.

and with a pale pubescence, a small space in front of the 
vertex smooth and shining. Thorax 1 line (scarcely) in

margin and the suture except at the base free. Hind 
body black, the segments punctured and pubescent except 
at their hind margins, the apex reddish. Legs, including 
the cox, reddish; the tibiz infuscate. 

Kga; a single female individual. 

This species is again very closely allied to 7. cinerea, 
but besides being considerably smaller, it has the legs 
shorter and paler, and the punctuation of the thorax and 
elytra a little coarser. The individual described is much 
rubbed, but I do not think the pubescence would differ 
materially in fresh individuals from that of 7. cinerea.

very narrow, shining black; the basal segments rather 
coarsely but not closely punctured, their hind margins 
impunctate; apical segments finely and sparingly punc-

longer, the pale pubescence of the upper surface is less 
conspicuous, and is absent from a larger portion of the 
elytra. 


PINOPHILUS. 


This genus, as at present understood, consists of about 
fifty species, inhabiting the warmer parts of the Old and 
New Worlds in about equal proportions: it is probable, 
however, that the species are really more numerous in the 
New World than in the Old; for while in Europe the 
genus is only represented by an eastern species that has 


Staphylinide of the Amazon Valley. 319 


extended its habitat to the island of Sicily, in America, 
north of Mexico, several species occur, some of them, 
indeed, being apparently not uncommon there. 

Mr. Bates has discovered a remarkably fine series of the 
genus, no less than twenty-four species being here de- 
scribed; of these Pinophilus dux is to be ranked amongst 
the largest of the Staphylinide, while other species are 
insignificant in size. One of the species, P. mimus, is 
remarkable from its great general resemblance to Lathro- 
bium opalescens, the two species being, I believe, found 
living together. 

As is also the case with some of the Amazonian species 
of Lathrobium and other genera, certain of the species 
here described bear the most complete resemblance to one 
another in their general characters, but are distinguished 
by well-marked external and internal sexual characters.

raceque nitidis, vage punctatis; elytris subnitidis, fortiter

The largest and most powerful species of the genus, 
being considerably broader and slightly longer than P. 
tenebrosus. Antennz rather short and stout, obscure 
reddish, the basal joints pitchy red. Head short and 
broad, shining black, sparingly and irregularly punctured ; 
the punctures coarse, almost ocellated, and bearing fine 
sete. Thorax just about as long as broad, a little nar- 
rowed behind, with all the angles rounded, shining black, 
coarsely and sparingly punctured, with punctures similar 
to those of the head, and irregularly distributed, a longi- 
tudinal irregular space along the middle being free from 
punctures ; outside this an irregular double row of punc- 
tures, then a narrow very irregular space almost free from 
punctures, then a broad space at the sides with scattered 
punctures. LElytra slightly narrower than the thorax, 
and scarcely longer ; rather coarsely and sparingly punc- 
tured, and very finely and sparingly pubescent. Hind 
body elongate and parallel; the segments rather coarsely 
and closely punctured and finely ‘pubescent, the apical 
ones with the punctures coarser and more elongate than 
the others, but not rugose ; the apex rather deeply emargi- 
nate. 

Ega; a single female specimen.

This species appears to be closely allied to P. torosus, 
Er., a species which I know only by description. P. > duz 
would seem to be larger than torosus, and it has not the 
apical seements of the hind body rugose ; other details of 
Erichson’s description of P. torosus do not seem very 
applicable to P. dux, so that if a comparison of the two 
species were made it is possible they might be found to 
differ in other minor points.

the head, dull red; the basal joints stout, the 3rd joint 
distinctly longer ian 2nd. Mandibles wail a long tooth. 
Head shining black, with a few large punctures about the 
middle, and also some very minute punctures; the hind 
angles rather closely punctured. Thorax distinctly longer 
than broad, quite as broad as the elytra, quite straight at 
the sides, with the hind angles much rounded; very 
shining black, sparingly punctured, near the middle two 
irregular rows of punctures, and with some other scattered 
punctures about the sides and front, and the surface 
besides is sprinkled with very minute punctures. Elytra 
scarcely longer than the thorax, rather coarsely but not 
densely punctured. Hind body rather coarsel y and closely 
punctured, its extremity reddish, truncate, and with a 
small spine on each side the truncation ; the apical seg- 
ments rather more sparingly punctured than the preceding 
ones. The legs are pitchy, with the tarsi reddish; the 
metasternum has a fine channel along the middle. 

Tapajos; a single female specimen, from which the 
pubescence has been removed. This species is about the 
size of our Ocypus ater. It is larger and more parallel 
than the North American P. picipes, and differs there- 
from by the large tooth of the mandibles.

and parallel, longer than broad, quite straight at the 
sides, moderately coarsely punctured, shining, the punc- 
tures irregularly distributed, leaving a narrow space along 
the middle smooth; outside this a space where the punc- 
tures are crowded together, then again an ill-defined space, 
most distinct towards the front, free from punctures, the 
sides again more closely punctured especially on the 
hinder part. Elytra oblong, quite as long as the thorax, 
rather coarsely and closely punctured. Hind body closely 
and rather coarsely punctured, generally reddish at the 
extremity; the apex of the upper terminal plate is not 
truncate, but a little rounded or produced in the middle, 
with a short spine on each side. Legs clear red. 

In the male the trochanters of the hind legs are acu- 
minate at the extremity, and the thighs are armed in the 
middle beneath with a sharp tooth; the 6th ventral seg- 
ment is depressed in the middle towards the extremity, 
the hind margin narrowly emarginate; the 7th segment 
has a rather broad and deep emargination at the extremity, 
in front of which it is flattened or depressed.

Antenne red, slender and elongate, quite as long as 
head and thorax ; 3rd joint one and a half times the length 
of 2nd. Head almost as broad as thorax, very shiming, 
the upper surface with a few coarse punctures, most nume- 
rous about the hind angles, but nearly wanting in the 
middle of the vertex. Thorax oblong, longer than broad, 
quite straight at the sides, shining, rather finely and not 
densely punctured, the punctures leaving an irregular 
space along the middle, and a round space near the front 
angles, impunctate. Elytra slightly longer than thorax, 
rather coarsely and not densely punctured. Hind body 
not densely punctured, reddish at the extremity. 

Ega; a single female. 

This species, though closely allied to P. mimus, is abun- 
dantly distinct by its larger size, more elongate thorax, 
and the more sparingly punctured front parts of the upper 
surface; the extremity of the hind body is simple, as in 
P. mimus, but I have not ascertained whether the 5th 
segment bears a transverse line or not.

rather stout, not thinner at the extremity; 3rd joint a 
little longer than 2nd. Head small, shining, dark reddish, 
with a very few punctures. Thorax longer than broad, 
about as broad as the elytra, quite straight at the sides, 
shining red, with a few fine punctures, viz., four distant 
ones in a row on each side of the middle, and five or six 
on each side near the margin. Elytra a little longer than 
the thorax, infuscate, rather finely and sparingly punctured, 
but slightly shining. Hind body dull, infuscate, reddish 
at the extremity, the punctuation indistinct, moderately 
close. Legs yellowish-red ; extremity of hind body simply 
rounded.

Antenne yellow, slender, moderately long; 3rd joint 
a little longer than 2nd. Palpi pale yellow; mandibles 
pitchy. Head with the vertex densely punctured ; in front 
of this with a transverse, quite shining space, the anterior 
part with coarse punctures on each side, and two mode- 
rately large punctures on the front edge of the clypeus in 
the middle. Thorax one-fourth longer than broad, quite 
straight at the sides, densely, moderately coarsely and 
evenly punctured, the punctures covering the whole sur- 
face and leaving no smooth spaces. Elytra scarcely longer 
than the thorax; their punctuation very similar to that of 
the thorax, their hind margin obscurely red. Hind body 
moderately coarsely and not closely punctured, the extre- 
mity broadly red. The legs are pale yellow; the anterior 
tarsi extremely broad. 

The male has the ventral plate of the 7th segment 
almost simple; it is not produced, and only very obsoletely 
emarginate at the extremity; the ventral plate of the 8th 
segment is visible and rather broad, and remains part of 
the sheath, it not being modified to form part of the intro- 
mittent organ; the form of the latter is very peculiar.

its Indian allies, rather than to the other Austro-Columbian

error in the indication of its locality.

Antenne yellow, very slender, 3rd joint about as long 
as 2nd. Head short, black, mandibles and front of clypeus 
pitchy red, dull, the front part with large distant punctures, 
the vertex on each side coarsely but obsoletely punctured. 
Thorax not quite so long as broad, slightly narrowed 
behind, very dull, sparingly and extremely obsoletely 
punctured ; in the middle in front of the base with a short, 
very obscure, longitudinal elevation. Elytra a little longer 
than the thorax, quite dull, densely punctured ; the punc- 
tures moderately coarse, the interstices rugulose. Hind 
body narrow, quite dull, indistinctly punctured, the punc- 
tuation obscured by a coarse pubescence. Legs pale 
yellow, with the cox dusky reddish, the front tarsi very 
broad. 

In the male there is a small but distinct notch at the 
extremity of the ventral plate of the 7th segment of the 
hind body; the ventral plate of the 8th segment is enfolded 
by the dorsal plate; it is narrowed towards the extremity, 
and furnished there with two small hooks placed at right 
angles to the rest of the plate; in the female this plate is 
broader and visible, and has a triangular notch at the 
extremity. 

Tapajos; several specimens; one immature specimen is 
quite pale brown; I have also a male specimen from Ega 
which differs only in being broader and a little more 
depressed.

Head dull, front part with sparing coarse punctures, 
punctuation of the vertex obsolete. Thorax quite as long 
as broad, quite straight at the sides, not narrowed behind, 
quite as broad as the elytra; its surface dull, sprinkled 
with distinct, though very slightly impressed, moderately 
fine punctures. Elytra slightly longer than the thorax, 
dull, rather coarsely and moderately closely punctured, 
the interstices larger than the punctures. Hind body 
rather slender, its punctuation indistinct, rather coarse, 
but shallow and not dense, concealed by a coarse pubes- 
cence. -The legs are pale yellow, with the coxz reddish ; 
the anterior tarsi very broad. 

Tapajos; two specimens, both females; the extremity 
of the hind body is formed as in P. incultus 2, to which 
species, as well as to P. proximus, the present spécies is 
closely allied, but it may readily be distinguished by its 
more slender form and more sparingly punctured elytra.

the 7th ventral segment is smooth, being quite free from 
punctuation or pubescence, and shows no trace of emargina- 
tion; the ventral plate of the 8th segment is enfolded and 
concealed by the dorsal plate; it is elongate and slender 
(when dissected out), its basal portion only slightly broader

more sparing towards the front, so that it is there shining ; 
also with some coarse punctures on each side in front of 
the middle, and with the vertex coarsely but not deeply 
punctured. Thorax about as long as broad, distinctly 
narrowed behind, dull, coriaceous, and with rather coarse 
but only little impressed punctures, which are rather more 
distinct about the middle than elsewhere; there is no 
definite longitudinal space free from these punctures, but 
just in front of the base is a small, shining, longitudinal 
elevation. The elytra are slightly longer than the thorax, 
quite dull black, obscurely reddish at the extremity, covered 
with a rather deep, but only moderately coarse and close 
punctuation. Hind body reddish towards the extremity.

opaque behind, the back part coriaceous, and the hinder 
angles with obsolete, very coarse punctuation ; the front 
part with sparse, fine punctures, with two coarse ones in 
the middle, immediately behind the labrum, and with four 
or five other large punctures obliquely placed on each side, 
near the front. Thorax about one-fourth longer than 
broad, a little narrowed behind, with extremely coarse, 
shallow punctures; the interstices very shining, the punc- 
tures opaque, being coriaceous; along the middle with two 
broad, longitudinal impressions, rather deep behind, indis- 
tinct towards the front; in these impressions the punctures 
are confluent; small spaces near the front and hind angles 
are free from punctures. Elytra hardly longer than the 
thorax, coarsely and closely rugosely punctured. Hind 
body dull, rather closely, moderately finely punctured. 
Legs pale yellow, coxze pitchy. 

Inthe ¢ the under part of the 7th segment of the hind

This species resembles extremely the P. bisulcatus, but 
differs by its male characters. In other respects it may 
be said to resemble that species exactly; the single speci- 
men I have seen exhibits some slight differences in sculp- 
ture, the punctuation of the upper surface being a little 
coarser; this is more notable on the thorax than elsewhere, 
so that the coarse punctures are more confluent, and the 
shining interstices more reduced in extent. 

I have no more special locality for this species than 
«* Amazons,” but I suspect it to be from the upper portion 
of the river.

of coarse distant punctures, and the vertex with sparing 
coarse punctures. Thorax about as long as broad; the

Ega, a single specimen ; also without special locality 
two other specimens, male and female, which I suspect 
represent a closely allied species, but may perhaps be a 
variety of this species ; they have the thorax more sparingly 
punctured, and the male has the antennz with the joints 
a little differently shaped, but this may possibly depend on 
a slight shrivelling of these delicate structures. P. pal- 
matus, Er., is evidently a closely allied species.

closely punctured. Hind body reddish, with the 6th and 
7th segments infuscate in the middle, and their hind 
margins very pale; the segments are rather closely punc- 
tured, but shining. The legs are white; the front tarsi 
very broad, the hinder ones slender and elongate. 

In the male the front tibie are furnished at the extre- 
mity (or perhaps the tarsi at the base) with a stout process, 
which projects inwards, and is broader at the apex than 
the base; the ventral plate of the 7th segment is slightly 
produced in the middle, that of the 8th segment is in- 
ternal; the sides of the dorsal plate greatly overlapping 
one the other at the base. 

Tapajos ; two specimens. 

This is a very curious species, and will probably form a 
distinct genus.

cessor, each distinctly longer than broad. Palpi elongate, 
white, the terminal joint slender and elongate. Head 
much smaller than the thorax, very shining black; the 
mandibles red; the antennal tubercles reddish; a single 
fine puncture on the front margin of the clypeus, a depres- 
sion inside the tubercles, and behind this two punctures 
on each side, and a few punctures on each side of the 
vertex. Thorax very shining, black, about as long as 
broad, transversely convex, not narrowed behind, with an 
irregular row of four or five coarse punctures on each side 
the middle; with four or five others outside these, some 
fine punctures on the front margin, and with a few fine 
obsolete punctures scattered over the surface. Scutellum 
black, not punctured. Elytra slightly longer than the 
thorax, shining red, deeply and very coarsely punctured, 
the punctures not dense. Hind body short, opaque, the 
segments obscurely punctured, the three or four basal 
ones with ashy pubescence on each side; the 7th segment 
white, with a black patch on the middle. Legs rather 
stout, white. The sternum, with the coxe and under 
face of hind body, reddish. 

In the male the ventral plate of the 7th segment has the 
middle part greatly produced, so as to form a large tongue- 
like process; it is separated by a deep notch from the 
lateral portion, and is finely punctured in the middle; 
that of the 8th segment forms part of the intromittent 
organ; it is polished and quite smooth, from beyond the 
middle gradually narrowed to the extremity, where it forms 
a sharp spine. 

Amazons; a single male, without special locality. 

This very remarkable species is allied to the P. egens, 
though extremely different from it in appearance. I should 
suppose the Columbian P. crassicollis, Er., may be an 
allied species. 


CEDODACTYLUS. 


The two species here described are only referred wit! 
doubt to the genus Qdodactylus, hitherto representea 
only by G2. fuscobrunneus, from Chili. They are re- 
markable by the elongate anterior coxz, and the great 
development of the side pieces of the thorax, and may be 
considered the Austro-Columbian representatives of the 
Arctogeal and Australian Procirrus, to which genus the 
Chilian species approaches in facies more nearly than do 


Staphylinide of the Amazon Valley. 337 


the two Amazonian insects. ‘These, moreover, are dis- 
cordant in appearance inter se; the sculpture and some 
of the details of G. anceps recalling Sunius, and I 
think it quite possible that a real affinity in that direction 
will be detected. The genus Procirrus is one of the 
most remarkable of the Stuphylinide, from the fact that 
the very elongate front coxe are entirely exserted, there 
being only a small circular opening at the extreme front 
angle of the thorax for their insertion. This peculiarity 
appears to result from an unusual and extreme development 
of the ento-thorax, and from certain parts thereof, that 
are usually membranous, becoming horny. Certain other 
members of the Pinophilini (Pinophilus latipes, e. g.) 
offer us the existing intermediate stages of this transform- 
ation ; and it appears to me probable that the gradations 
of metamorphosis of this part will offer the most important 
clue to the classification of the members of the group.

longer than the very slender 3rd joint; jomts 4—11 each 
very slender at the base, and longer than broad. Maxil- 
lary palpi yellow, last joint less produced inwardly than in 
CE. errans. Head small, narrower than the thorax, closely 
and rather coarsely but not deeply punctured, the interstices 
slightly shining. Thorax about as long as broad, with 


the base rounded, so that the hind angles have disappeared ; 
it is slightly lobed in the middle in front, the front angles 
nearly right angles; it is densely punctured, the punc- 
tures on the middle shallow, subocellate, the sculpture at 
the sides and base granular. Elytra a little longer than 
the thorax, dull, densely punctured with an asperate 
punctuation, Hind body slender and elongate, pointed at 
the extremity, densely punctured. Lees rather long, 
yellow, front tarsi elongate and (for the group Pinophilin?) 
narrow. 

Tapajos; a single individual. It is, I believe, a male, 
but the extremity of the hind body is retracted, and I 
have damaged the specimen in trying to withdraw it. 


CE pICcHIRUS. 


This genus has not been registered as found in the New 
World, but my collection contains six or eight species 
from South America. According to a note of Mr, Bates 
the G2. optatus here described is found on trees. 

I believe the Elytrobeus geniculatus, Sahlberg, from 
description (Act. Soc. Fenn. 2, p. 802), to be an insect of 
this genus, the characters mentioned as separating the 
genus from Gdichirus appearing to me very indefinite. 
Amongst these, Sahlberg lays stress on the last joint of 
the antenne terminating ina spine. On examining the 
European G2. pederinus, I find that in some individuals 
the antennz end in a short spine or seta; and of the 
three specimens I possess of @?. optatus, the two females 
have the extremity of the antennx truncate, while in the 
male these organs are terminated by a slender but rather 


Staphylinide of the Amazon Valley. 339 


long spine or seta. I have not, however, made any 
allusion to this in my description, for I am not at all clear 
that this character is more than illusory. It appears to 
me probable that the apex of the antenne is formed by a 
projecting membrane which bears the spine, and that the 
membrane can be retracted, in which case the spine dis- 
appears, and the extremity of the antenna is apparently 
truncate.

Antenne yellow; 14 lin. in length, 2nd and 3rd joints 
about equal. Palpi and mandibles yellow. Head broad 
and short, the front half bearing ten or twelve coarse 
punctures; the clypeus in front smooth, the vertex with a 
few coarse punctures on each side; the hind part bounded 
on either side by a slightly raised carina. Thorax fully 
# lin. in length, and about 2 in its greatest width, very 
much narrowed behind, of a shining pitchy colour like 
the head; the sides in front greatly deflexed, the surface 
bearing very coarse punctures, consisting of two irregular 
rows of about a dozen punctures each along the middle, 
these rows separated on the basal portion by a broad 
smooth space, but on the anterior portion between them 
about five coarse punctures on each side, so as to occupy 
there the middle space; near each side is a shorter row 
of punctures divergent towards the front; between this and 
the middle three or four punctures in front of the middle, 
and also with punctures along the base and margins. 
Scutellum moderately large, smooth. LElytra, from the 
apex of scutellum to extremity of suture, ~ lin. in length, 
curved at the sides and much narrowed at the base, rather 
paler-pitchy in colour than the thorax; their hind angles 
projecting a good deal behind, the surface bearing coarse 
ill-defined punctures and a few long hairs. Hind body 
ample, the segments coarsely punctured, the 6th and 7th 
segments only obsoletely and sparingly punctured; the 
surface is but little shining, the basal portion of each 
segment being coriaceous; the punctures are quite irre- 
gularly disposed. Ths legs are entirely pale yellow.

PALAMINUS. 


The species of this genus hitherto described are only 
about twelve, and of this number only five are from 
South America, the others inhabiting North America, 
Ceylon, and the Cape Verde Islands. Nevertheless the 
species in South America are excessively numerous, my col- 
lection containing about sixty species from that continent. 
The genus is one of those where the examination and 
description of the species in a thoroughly satisfactory 
manner is surrounded with great difficulties. These 
insects are small and delicate, and the different species 
bear the greatest resemblance inter se, and apparently in 
some cases are found together in a gregarious manner. 
In order to distinguish the species a very careful examina- 
tion of the sexual characters should be made, and this 
ought to include an examination of the appendages of the 
male intromittent organ; these are very different in the 
different species, and in certain cases are extremely re- 
markable; bilateral asymetry is very common. The 
external abdominal sexual characters are in some species 
striking, while in others they are scarcely present. I 
cannot mention any general external characters by which 
the sex of an individual may be distinguished with cer- 
tainty, but, as a rule, it appears that an excision or notch 
at the hind margin of the ventral plate of the 7th seement 
is characteristic of the female, while a conspicuous pro- 
longation of that part generally indicates the individual 
possessing it to be a male. Erichson (who in his * Genera 
and Species” has only described four species of the 
genus) appears to have probably fallen into error in his 
identification of the sex of the individuals described by 
him; in the case of one of the species, P. variabilis, 
he enumerates five or six varieties, all of which will, I 
have no doubt, prove to be distinct species. Twenty 
species found by Mr. Bates are here described, as well as 
one other captured by Dr. Trail, and, after comparing 
them carefully with a large series of species found in the 
neighbourhood of Rio de Janeiro, I find not a single one 
is common to the two localities.

Long. corp. 23—2% lin. 

Mas et femina: abdomine segmento 7° ventrali sim- 
plice. 

An elongate and slender species. Antenne almost 
white, longer than head and thorax; 3rd joint elongate, 
longer than the 2nd joint; 11th joint simple, scarcely so 
long as, and slightly broader than, the 10th. Palpi pale 
yellow, with the last jomt very large. Head yellow, the 
vertex slightly emarginate, the eyes reaching very near to 
the back of the head, with a fine margin behind them; 
the surface is rather coarsely punctured, the punctures, 
however, not sharply defined, and become more obsolete 
and sparing towards the vertex. Thorax fully as long as 
broad, the sides not curved but much narrowed behind ; 
the surface rather coarsely and irregularly punctured, the 
punctures towards the sides more indistinct than about 
the middle, the smooth spaces not conspicuous. Elytra 
slender but considerably broader than, and about one and 
a half times the length of, the thorax; deeply emarginate 
behind, so that the outer angle reaches considerably farther 
back than the suture; ferruginous yellow, slightly darker 
about the suture; rather deeply and moderately coarsely 
punctured, the punctuation at base rather close, sparing 
at the extremity. Hind body slender, darker and less 
shining than the other parts, ferruginous ; the four basal 
segments coarsely sculptured, the two apical ones smooth. 
Legs slender and elongate, almost white, basal joint of 
hind tarsus forming rather more than half the length of 
the tarsus. 

The 7th abdominal segment is nearly similar in the 
two sexes, and shows no peculiar structure; the terminal 
joint of the maxillary palpi is, however, considerably larger 
in the male than in the female, and the dorsal plate of 
the 7th segment is just a little more prolongéd in the 
middle. 

Tapajos, Ega; five individuals, 3 2, 2 ¢; also a female 
individual from Tapajos, which is much broader than the 
Ega specimens, so that I think it probable a knowledge 
of the male might show it to be a distinct species.

Fem.: abdomine segmento 7° ventrali simplice. 

Very closely allied to P. simplex, but the vertex is more 
emarginate, so that the fine line which bounds the vertex 
is not so straight; the insect is also rather less slender, the 
thorax is bronders in proportion to its length, and has the 
sides a little rounded and the central space more distinct, 
and the pubescence of the hind body is more conspicuous.

Antenne white, slender and very elongate, much longer 
than head and thorax. Palpi with terminal joint very 
large. Head rather small, the vertex almost straight; the 
punctuation similar to that of P. simplex. Thorax about 
as long as broad, a good deal rounded at the sides but not 
greatly narrowed behind; its surface coarsely and irregu- 
larly, not densely punctured, the central space rather con- 
spicuous behind. Elytra broader than the thorax, and 
nearly one and a half times as long; their punctuation 
rather coarse, but not dense. Hind body with the pubes- 
cence long and conspicuous; the sculpture of the four basal 
segments coarse, the two apical ones smooth. Legs white ; 
hind tarsi elongate and slender. 

In the male the middle portion of the ventral plate of 
the 7th segment of the hind body is a good deal produced ; 
the hind margin is rounded, and has a small, sharply 
defined notch in the middle. 

Kga ; a single male. 

Though this species greatly resembles P. simplex, it 
may be very readily distinguished by the male characters ; 
though the female is unknown to me, the different form of 
the thorax from that of P. simplex will no doubt be com- 
mon to it and the male. The species bears a still greater 
resemblance to P. longicornis, but the head is smaller, the 
vertex less emarginate, and the thorax less narrowed behind.

Antenne very slender, moderately long, almost white ; 
3rd joint very slender, a good deal longer than the 2nd; 
joints 4—8 each very slender, and a little shorter than 
its predecessor (the three terminal joints are wanting in 
the individual described). Palpi pale yellow, terminal joint 
moderately large. Head large, broader than the thorax, 
and about as broad as the elytra; the eyes distinctly 
removed from the posterior angles, the vertical line 
strongly marked, much deflexed in the middle, owing to the 
emargination of the vertex, and also interrupted in the 
middle; the surface is coarsely and not densely punctured 
with distinct, well defined punctures, most numerous 
between the front part of the eyes, and wanting at the 
extreme vertex. Thorax rather broad, its length rather 
less than its width, a little rounded at the sides, and much 
narrowed behind; the surface sparingly and irregularly 
punctured with well-defined punctures, these forming a 
patch on each side the middle; the sides but sparingly 
punctured, the smooth spaces well marked but not elevated. 
Elytra one and a half times as long as the thorax, rather 
paler in colour than the rest of the upper surface, their 
punctuation moderately coarse and close. The legs are 
almost white. 

Amazons. 

The single female individual, the only one I have seen of 
this species, is very mutilated, and shows no peculiarity of 
abdominal structure; but the species will be easily recog- 
nized by the broad head and the well-defined punctures of 
the head and thorax, in which respects it resembles some of 
the black species here described rather than any other pale 
species I am acquainted with.

not very large. Head very short, broad, almost as broad 
as the thorax; the vertical line fine, very slightly deflexed 
in the middle, contiguous at the sides with the hind margin 
of the eyes, slightly interrupted in the middle; the surface 
is coarsely and rather closely punctured. Thorax a good 
deal broader than long, slightly narrower than the elytra, 
the base and hind angles rounded; the surface rather 
coarsely and closely punctured, so that the smooth spaces 
are almost absent. Elytra not quite one and a half times 
the length of the thorax, rather closely and only mode- 
rately coarsely punctured; the punctures near the scutellum 
dense, at the extremity distinctly more sparing. Hind 
body broad, darker in colour than the front parts; the two 
apical segments without imbricate punctures. Legs pale 
yellow, rather stout and short, 

In the female the ventral plate of the 7th segment of 
the hind body is produced and has a large deep notch in 
its apical portion ; the sides of this plate come to a point 
at their termination, and are a little curved upwards.

When I first examined it, I supposed this individual to 
be a male; but as on dissection I find no trace of the 
edeagus, I conclude, with something like certainty, that 
it is a female.

The head is short, with the vertex scarcely emarginate ; 
the vertical line is fine, contiguous at the sides with the 
eyes, only slightly deflexed, and interrupted in the middle. 
The thorax is about as broad as the head, but a little nar- 
rower than the elytra, its length considerably less than its 
width ; the sides only slightly curved, and a little narrowed 
behind, the hind angles obtuse but not rounded ; its sur- 
face covered with rather coarse punctures, which become 
wanting at the front angles, but leave no distinct space 
along the middle smooth; the base in front of the middle 
slightly bi-impressed. LElytra quite one and a half times 
the length of the thorax, rather closely and coarsely punc- 
tured, with the punctures much more sparing at the extre- 
mity. Hind body rather slender, darker in colour than 
the front parts; the four basal segments with imbricate 
sculpture. The legs very pale yellow, rather short. 

The female has a rather br oad, moderately deep notch 
in the middle of the extremity of ‘the ventral plate of the 
7th segment of the hind body. 

Amazons, probably Tapajos; a single female. 

This species appears rather closely allied to P. robustus, 
but is very much more slender; it has the thorax shorter 
and the elytra less densely punctured, and in the female the 
lobes at the sides of the notch of the 7th segment are not 
acuminate. Though the antenne are broken, ‘they probably 
much resemble those of P. robustus ; ; the two basal joints 
which remain are quite as short, but hardly so stout~as in 
P. robustus.

the vertical line fine, at the sides very near to the eyes, 
scarcely deflexed and slightly interrupted in the middle. 
Thorax a little shorter than broad, distinctly narrower 
than the elytra, curved at the sides and a good deal nar- 
rowed behind; the colour reddish, but much infuscate; the 
punctuation rather fine; the surface with two impressions 
on the middle towards the base, separated by a slight, 
raised, smooth space. LElytra about one and a half times 
as long as the thorax, their punctuation sparing except 
about the scutellum; they are reddish in colour at the 
base, pale yellow at the extremity. Hind body rather 
dark red, with the 7th segment, and the 8th infuscate ; 
four basal segments with imbricate sculpture. Legs pale 
yellow. 

The female has the ventral plate of the 7th segment of 
the hind body distinctly emarginate at the apex.

than 2nd; last joint broader than the 10th, and as long as 
the 9th andl 10th together. Palpi pale yellow, terminal 
joint small. Head small, with the vertex scarcely visibly 
em arginate ; the vertical: line dine and indistinct, at the 
sides contiguotis with the eyes. Thorax a good deal nar- 
rower than. the elytra, quite as broad as the head, a good 
deal broader than long, curved at the sides, and a good 
deal narrowed behind; its surface coarsely punctured, 
without smooth middle space and only extremely obsoletely 
bi-impressed. Elytra about twice as long as the thorax, 

rather closely punctured at the base; the punctures be- 
coming gradually more sparing towards the extremity, 
where they are nearly entirely wanting. Hind body red- 
dish, darker than the front parts; the four basal segments 
with imbricate sculpture. Legs almost white, rather 
short. 

Ega; a single individual, whose sex is uncertain ; the 
ventral plate of the 7th segment is very slightly produced,

A rather slender species. Antenne long and slender, 
pale yellow, distinctly longer than head and thorax; 3rd 
joint very slender, elongate, considerably longer ee 2nd; 
11th joint slender, only slightly broader than 10th. Palpi 
pale yellow, only moderately large. Head quite as ena 
as the thorax, but slightly narrower than the elytra; the 
vertex a little emarginate, the vertical line fine, at the

sides very close to the eyes, only slightly deflexed in the 
middle; the surface rather coarsely but not closely punc- 
tured. ‘Thorax about as long as broad, a good deal nar- 
rowed behind but hardly at all curved at the sides, irre- 
gularly punctured; the middle with two series of punctures, 
divergent towards the front, joined together in front of 
the base, and slightly impressed behind, the front part of 
the included space bearing large punctures, so that only 
a small part behind is free from them; outside these 
central series are a few punctures scattered at the sides. 
Elytra about one anda half times the length of the thorax, 
coarsely but not closely punctured, the punctures more 
sparing towards the apex. Hind body with the four basal 
segments with imbricate sculpture, the two apical ones 
smooth. Legs pale yellow, rather long. 

The female has the dorsal plate of the 7th segment of 
the hind body with a curved emargination on each side, 
between which the hind margin is a little rounded, but 
slightly truncate in the middle; the ventral plate has the 
hind margin almost truncate, but with a slight emargina-

This insect resembles extremely the P. niger, but has 
the thorax rather different, the sides being a little more 
curved, but less narrowed behind, and the elytra are 
slightly more finely and closely punctured; these diffe- 
rences are but slight, and it is possible that the single 
individual I have seen may be the male of P. niger. 

The dorsal plate of the 7th segment of the hind body is 
much rounded in the middle, and deeply sinuate on each 
side; the ventral plate is a good deal produced, and the 
produced part would have the form of half of an oval 
plate, were it not for a small notch in the middle at the 
extremity.

Obs.—P. modestus, above described, resembles this 
species, both in the external characters of the male and 
the structure of the aedeagus, but differs strikingly in 
colour; it is just possible, however, as all other characters 
seem to agree, that P. modestus is only an immature form 
of the P. anceps.

Antennz pale yellow, rather slender, moderately long ; 
3rd joint distinctly longer than 2nd, Lith a little stouter 
than 10th. Palpi pale “yellow. Head about as broad as 
the thorax; the vertex a good deal emarginate, the vertical 
line contiguous with the eyes at the sides, strongly deflexed 
in the middle, and distinctly interrupted by a longitudinal 
depression; the surface coarsely, distinctly and closely 
punctured. Thorax quite as long as broad, greatly nar- 
rowed behind, but not in the least rounded at the sides, 
the middle part closely punctured; in front of the base 
a slightly raised longitudinal smooth space in the middle, 
the lateral margins sparingly punctured. Elytra scarcely 
one anda half times the length of the thorax, rather coarsely 
punctured, the punctures not very close, the apical margin 
quite smooth. Hind body with imbricate sculpture on the 
four basal segments, and also on the anterior part of the 
following segment. Legs pale yellow, rather long. 

The structure of the 7th abdominal segment is but little 
dissimilar in the two sexes, the hind margins being almost 
simple; the terminal joint of the maxillary palpi is, how- 
ever, considerably larger in the male than in the female. 

Tapajos ; ; two individuals, male and female.

Antenne pale yellow; 3rd joint slender, a good deal 
longer than 2nd; joints 4—6 rather short (a good deal 
shorter than in P. sobrinus), the others broken off. Pal pl 
pale yellow. Head slightly broader than the thorax, ‘he

tudinal depression ; the surface convex, coarsely, distinctly 
and rather closely punctured. Thorax not so long as 
broad, a little rounded at the sides, and narrowed behind ; 
in the middle is a smooth shining space, not reaching the 
front, and on each side of this the surface is slightly de- 
pressed, the depressions coarsely and closely punctured ; 
towards the sides, in the middle, are some other punctures, 
as also in front of the smooth space, and a few at the lateral 
margins and base. Jlytra more than one and a half times 
the length of the thorax, distinctly and rather closely punc- 
tured, the punctures becoming only a little more sparing 
towards the extremity, but the apical margin quite smooth 
and impunctate. Hind body slender; the four basal seg- 
ments with imbricate sculpture, and the anterior portion 
of the following segment with similar but less distinct 
sculpture. Legs pale yellow, rather long. 

The male shows little peculiarity in the structure of the 
7th segment of the hind body. 

Tapajos; a single male specimen. 

Obs.—This species greatly resembles P. sobrinus, but 
may be readily distinguished by the shorter thorax ; the 
elytra also are more closely punctured. The structure of 
the edeagus is not very dissimilar in the two species, but 
its size in P, sobrinus is double that of P. puncticeps.

than the thorax; the vertex greatly emarginate, the vertical 
line coarse, at the sides remote from the eyes, greatly de- 
flexed in the middle, and with a narrow interruption; the 
front part between the eyes coarsely and closely punc- 
tured, the vertical portion sparingly punctured, and at 
the back in front of the line the surface broadly coriaceous 
and opaque. Thorax about as long as broad, a good deal 
narrowed behind, and distinctly rounded at the sides; the 
surface coarsely but irregularly punctured, the punctures 
consisting of two broadly-separated, rather divergent series, 
between which, on the front portion, are two other series,

and between the middle and the sides are a few other 
punctures; the two main series are only very slightly 
impressed. Elytra about one and a half times as long as 
the thorax, the basal portion rather closely punctured ; 
the punctures become more spar ing towards the extremity, 
and at the apex are quite w anting. Hind body with the 
four basal segments with imbriente sculpture. Lees 
almost white, 1 rather long and slender. 

In the female the 7th segment of the hind body is 


simple, the hind margin of the dorsal plate being slightly 
rounded, while that of the ventral plate (which is scarcely 
longer) is almost truncate, being scarcely visibly emar- 
ginate in the middle. 

Tapajos ; a single female. Also from the same locality 
I have paemee female, which may possibly be a distinct 
species, the head being a little smaller and the elytra with 


rather more punctures towards the extremity.

25 lin. 


Head rather large, with the surface in front of the 
vertical line scarcely coriaceous. Thorax with two dorsal 
series of punctures convergent in front of the base; between 
these in front with a few punctures, and with a few other 
punctures between the middle and the sides; the main 
series scarcely impressed, but the portion between them 
distinctly elevated except in front. The elytra are rather 
sparingly punctured, the punctures becoming more sparing 
towards the extremity and altogether wanting at the apex. 

In the female the dorsal plate of the 7th segment of the 
hind body is nearly truncate, being only very slightly 
rounded in the middle; at the extremity the ventral plate i is 
scarcely longer than the dorsal one, and, like it, is rounded, 
though rather more distinctly, at the apex. 

Amazons; a single female, without special locality. 

Obs.— This species resembles P. parcus extremely, and 
differs from the description above given of that species 
only in the characters here mentioned.

Head large, broader than the thorax, about the width of 
the elytra; the vertex emarginate and depressed in the 
middle, the vertical line coarse but not much raised, de- 
flexed in the middle and interrupted, at the sides remote 
from the eyes; the surface coarsely punctured, the punc- 
tures moderately close on the front part, sparing towards 
the vertex, in front of the vertical line a little coriaceous. 
Thorax about as long as broad, the sides slightly rounded, 
distinctly narrowed behind; the surface sparingly punc- 
tured, the middle space broad and a little elevated behind. 
Klytra at the sides one and a half times the length of the 
thorax, even at the base sparingly and not closely punc- 
tured, the apical portion impunctate. Hind body with 
imbricate sculpture on the four basal segments. Legs 
almost white at the base; the tibize and also the extremity 
of the hind femora infuscate. 

External abdominal characters to distinguish the male 
are almost absent; the dorsal plate of the 7th segment has 
the hind margin very slightly rounded; the ventral plate 
is scarcely longer than the dorsal, and is truncate, with 
the outer angles rounded. 

Tapajos; a single male specimen.

This species greatly resembles P. fuscipes, but is rather 
larger and much broader, and has the elytra more closely 
punctured, especially at the extreme base; in all other 
respects the description above given of P. fuscipes will 
apply to the P. stipes.

a little stouter than 10th. Palpi yellow, with the last joint 
small (in the female). Head large, a little broader than 
the thorax, and almost as broad as the elytra; the vertex 
a good deal emarginate, the marginal line moderately 
remote from the eyes at the sides, in the middle much 
deflexed and a little interrupted; the surface coarsely 
punctured, the punctures rather close towards the front, 
widely separated at the vertex. Thorax broad, very 
nearly as long as broad, much narrowed behind, a little 
rounded at the sides, the front angles greatly rounded ; 
the surface sparingly and coarsely punctured, the punc- 
tures consisting of two divergent, rather widely separated 
series along the middle, with accessory punctures between 
them on the front part, and outside them with a few other 
punctures; the depression at the hind part of the main 
series is only slight. Elytra about one and a half times 
as long as the thorax, pitchy in colour, with a broad straight

STEN -ESTHETUS. 


This genus was characterized by me a year or two ago, 
for the purpose of describing an interesting species from 
Japan, which had no very near known ally. 1 was there- 
fore much astonished when, on examining the species here 
described, I found it to be so closely allied to the Japanese 
insect, that I have not been able to find any characters 
to distinguish it as a genus therefrom. The Amazonian 
species possesses the heteromerous tarsi, with the very 
elongate basal joint to the hind feet of the Japanese insect; 
and though I have not dissected the mouth of the New 
World species, its parts, so far as I can see, are quite 
similar to those of the S. sunioides. I have not, however, 
been able to see the base of the maxillary palpi in S. ¢dla- 
tus. In my description of the genus (Trans. Ent. Soc. 
Lond. 1874, p. 79) I neglected to mention the form of the 
labrum: it is large and simply rounded, without notch or 
denticulations, and seems quite similar in the two species ; 
in the S. cllatus the paraglosse (or possibly the sides of 
the ligula) project beyond the labrum, and have much the 
appearance of two slender denticles, so that it might readily 
be supposed, on a superficial examination, that the labrum 
was armed with two slender teeth in the middle. As 
regards the number of joints in the antennze I am still 
uncertain whether it be ten or eleven; if the latter number 
be correct, then there are two stout basal joints, of which 
the first is short and concealed by the elevation over the 
point of insertion. The position of the genus is un- 
doubtedly between Kuesthetus and Stenus, and the occur- 


Staphylinide of the Amazon Valley. 357 


rence of this form in South America as well as in Japan 
renders it highly probable that other links will be found 
between these two dissimilar genera. I may indeed here 
express my cpinion that the interesting genus Ctenomastaz, 
recently described by Kraatz, from Spain, should be placed 
next Huesthetus, and not among the Pederide; mdeed, 
the descriptions and figures of Kraatz and Fauvel appear 
to point out as generic distinction from Euesthetus only 
a slight difference in the insertion of the antenne. 


1. Stenesthetus illatus, n. sp. Castaneo-testaceus, fere 
glaber, subnitidus, capite, thorace, elytrisque crebre sat 
fortiter punctatis, abdomine subtilissime punctulato; tho- 
race subcordato, elytris hujus longitudine. Long. corp. 
12 lin. 


Antennz very slender, but with the basal joint stout, it 
being quite four times as broad, though scarcely so long 
as, the 2nd; joints 2—8 excessively slender, differing 
little from one another in length, 9 and 10 very slender, 
but distinctly broader than the preceding ones, 10th rather 
longer than 9th. Head short and broad, with the eyes 
rather broader than the thorax ; near the front with two 
distant foveze; moderately closely punctured; the punc- 
tures, when seen under a high power, are umbilicated, as 
in Sunius, but the interstices are broad, and covered with 
a very fine, intricate reticulation, which renders the surface 
nearly opaque; the eyes very convex, moderately large, 
coarsely facetted, reaching the broad vertex. Thorax a 
good deal narrower than the elytra, rather longer than 
broad; the sides a little rounded in front of the middle, 
narrowed behind the rounded part; the hind angles nearly 
right angles, not rounded; the surface rather coarsely 
sculptured, with sculpture similar to that of the head, 
but.the punctures deeper and the interstices narrower ; 
along the middle of the basal part are traces of two longi- 
tudinal impressions. Elytra about as long as and rather 
more coarsely punctured than the thorax. Hind body 
robust, but with the apical segments very narrow, exces- 
sively finely and indistinctly punctured, not shining. Legs 
slender, pale yellow. 

In the male, on the underside, the 4th and 5th seg- 
ments of the hind body are plicate in the middle, and the 
elevated part is slightly produced; the 6th has the hind 
margin slightly emarginate. 


358 Mr. D. Sharp’s Contributions to the 


Tapajos; one é, 2 ¢ individuals; a specimen was also 
found at Lages, near Manaos, by Dr. Trail, on the 5th 
January, 1875. 

Obs.—This species differs from S. sunioides by the 
larger and more convex eyes, which reach quite to the 
back of the head. 


STENUS. 


Although the species of this world-wide distributed 
genus seem to be everywhere amongst the most numerous 
of the Staphylinide, yet only fourteen or fifteen species 
have been as yet described from the warmer parts of the 
New World. The twenty-five species here described will 
help, therefore, somewhat to rectify this disproportion, and 
indicate that the genus is richly represented in South 
America, as elsewhere. 

Of these species the first eight might, I should have 
thought, have been properly placed in Erichson’s division 
I. B. Erichson, however, has described three or four 
species from Columbia (S. augur, &c.), which I judge 
from his descriptions are very closely allied to these eight 
species, and has placed them in his division I. A. I have 
therefore left these species without indication as to their 
position in Erichson’s classification of the genus. Species 
12 to 18 belong to a group of which the species are nume- 
rous in South America, but no species of it occur in 
Europe. Species 20—25 might be placed in a natural 
manner between the European S. eicindeloides and S. con- 
tractus. 


1. Stenus inspector, n. sp. Niger, subopacus, antennis 
fuscis, basi obscure testaceis, palpis flavis, pedibus testaceis, 
geniculis infuscatis; fronte excavata, vertice angustissime 
carinato; thorace profunde transversim rugoso-punctato ; 
elytris thoracis longitudine, dense fortiterque punctatis ; 
abdomine gracili, crebre, basi distincte, apice obsolete, 
punctato, submarginato; tarsis gracilibus, articulo 4° vix 
lobato. Long. corp. 24 lin. 

Antenne moderately long, pitchy, yellowish at the base ; 
3rd joint a good deal longer than 4th; the three apical 
joints distinctly stouter, the 10th distinctly longer than 
broad. Palpi pale yellow. Head with the eyes large, 
quite as broad as the elytra; the front distinctly excavated, 
the clypeus abruptly deflexed; the surface densely and 


Staphylinide of the Amazon Valley. 359 


coarsely punctured, obsoletely bisulcate, with an extremely 
narrow carina at the vertex. Thorax a good deal nar- 
rower than the elytra, a good deal longer than broad ; 
the sides rounded in front of the middle, and narrowed 
behind the middle; the surface covered with a very dense, 
transversely rugose punctuation. LElytra quite as long as 
the thorax, coarsely, deeply and very closely punctured, 
the shoulders standing abruptly out from the base of the 
thorax. Hind body slender and elongate, the basal seg- 
ment distinctly margined, the following segments each 
constricted in front of the middle; the constricted part 
obscurely margined, the apical part not margined; the 
surface rather closely punctured, the punctuation on the 
basal segment distinct, but not coarse, on the penultimate 
segments indistinct; the front part of the two basal segments 
finely carinate on the middle. Legs yellow, coxe pitchy, 
the knees infuscate ; the 4th joint of the tarsi small, and 
scarcely lobed. 

In the male the under surface of the 6th segment of the 
hind body is clothed with fine, pale-yellow pubescence, 
and is distinctly emarginate at the hind margin ; the 3rd, 
4th and 5th segments also have the hind margin very 
obscurely truncate in the middle, the 7th bears a narrow, 
very elongate notch. 

Kga; a single male. 

Obs.—I have not referred this species to any of the 
generally received sections, because doing so would be 
very likely to create confusion about it. The tarsi 
might be described as having the 4th joint simple, but 
this would not be strictly correct, and the same remark 
would be applicable if the hind body were described as 
unmargined. The species suggests at first sight an alli- 
ance with S. speculator.

so broad as the elytra, densely and coarsely punctured, a 
little excavate, distinctly bisuleate, and with a narrow 
central carina. Hind body slender; the basal segment 
marginate, and the anterior portion of the next following 
segment finely margined, the others immarginate; the 
segments rather closely punctured, the punctures on the 
basal segment quite distinct, but becoming less deep on 
the following segments, so as to be obsolete on the penul- 
timate sezments; the sezments bear also a fine, depressed, 
scanty, ashy pubescence. ‘The legs are long and slender, 
the hind tarsi elongate and slender, with the 4th joint 
simple ; the cox are pitchy black, the femora are yellowish, 
but somewhat infuscate towards the extremity, and the 
tarsi become more obscure in colour towards the apex. 

In the male the 6th segment beneath is broadly but 
faintly impressed along the middle; the impressed part is 
pubescent and densely punctured; the pubescence towards 
the apex of the segment is dense at each side of the 
impression, the hind margin scarcely emarginate ; the 
following segment bears a narrow elongate notch. 

Ega; two males. 

Obs.—This species is closely allied to S. inspector, but 
is undoubtedly distinct ; the character of the sculpture is 
very similar, but is less dense on the thorax and elytra of 
S. obductus ; and other less striking differences are con- 
veyed by the two descriptions; the tarsi of S. obductus 
have the 4th joint slender and simple. 


3. Stenus tinctus, n. sp. /Eneo-niger, vix nitidus, 
palpis flavis, antennis fuscis, basi cum pedibus testaceis,

Antenne pitchy, yellowish at the base, rather short ; 
palpi pale yellow. Head slightly narrower than the 
elytra, densely and rather coarsely punctured, a little ex- 
cavate, and with a distinct shining carina along the middle. 
Thorax distinctly narrower than the elytra, rather longer 
than broad, the sides much rounded in front of the middle; 
the surface covered with coarse and deep transverse ruge, 
with one or two of the interstices about the middle rather 
broader. Elytra rather short and broad, about as long as 
the thorax; the humeral angles well marked, coarsely and

closely punctured, with the interstices near the suture 
distinct, broader than the external ones. Hind body rather 
slender, subcylindric; the basal segment margined, the four 
following ones each with a slight margin on the basal 
portion; the segments rather closely but obsoletely punc- 
tured, the basal one rather more distinctly than the 
others, and with a carina at the base in the middle, the 
two following ones with more indistinct carinz; all the 
segments with a well-marked, fine, depressed, pale-yellow 
pubescence. Legs moderately long, reddish-yellow ; the 
femora, as also the tibize and tarsi, more obscure in colour 
in their apical portion; 4th joint of tarsi simple. 

In the male the underside of the 6th segment is flattened 
along the middle and finely pubescent; the 7th segment 
has a very elongate and narrow notch. 

Tapajos; a single male. 

Obs.—This species is very closely allied to S. obductus, 
but is more metallic in colour, rather less elongate in 
form, has the thorax with the sculpture rather coarser, 
the sides more rounded, the hind body more obsoletely 
punctured, and the limbs rather shorter and stouter.

Antenne short, yellowish, infuscate at the extremity ; 
palpi pale yellow. Head nearly as broad as the elytra, a 
little excavate, and distinctly carinate along the middle. 
Thorax longer than broad, a good deal rounded at the 
sides; the surface coarsely sculptured, with transverse 
ruge, the interstices of which are broad enough to be dis- 
tinctly shining. LElytra about as long as the thorax, 
coarsely punctured, with the interstices distinctly shining. 
Hind body slender, subcylindric; the basal segment mar- 
gined, the four following ones each with a slight margin 
on the basal portion; the segments rather closely but 
obsoletely punctured, the basal one rather more distinctly 
than the others, and with a carina at the base in the 
middle, the two following ones with more indistinct 
carine; all the segments with a fine, depressed, pale-yellow 
pubescence. Legs moderately long, reddish-yellow. 

In the male the underside of the 6th segment is flattened

slightly emarginate ; the 7th segment has a very elongate 
and narrow notch. 

Tapajos ; two males. 

Obs.—This species bears an extreme resemblance to 
S. tinctus, but is more slender; it is more shining, has 
the punctures on the elytra rather less crowded, so that 
the interstices are more shining, and the limbs are still 
shorter,

Antenne dusky yellow, infuscate towards the extremity, 
short; 10th joint about as long as broad. Head nearly 
as broad as the elytra, densely punctured, distinctly ex- 
cavate, and with a very fine but distinct shining carina 
along the middle. Thorax rather longer than broad, dis- 
tinctly rounded at the sides, deeply transversely rugose, 
the interstices narrow. LElytra about as long as the 
thorax, rather coarsely and closely punctured, the inter- 
stices wider on a space near the suture than elsewhere. 
Hind body rather closely punctured, the basal segment 
distinctly, the apical ones obsoletely ; the basal segment 
very finely carinated in the middle, the following two only 
very obsoletely carinate. 

Tapajos; a single female. 

Obs.—I have some doubts whether the individual above 
described be really distinct from S. cognatus. It is just 
the same size as that species, but has the antennz a little 
shorter, the vertex more finely carinate, the interstices of 
the sculpture on the thorax and elytra rather narrower, 
and the carine of the basal segments of the hind body less 
distinct. These differences, however, are but slight, and 
it is possible may be sexual or individual rather than 
specific characters. I have, however, another female from 
St. Paulo which agrees in these respects with the S. vacil- 
lator, and is probably conspecific with it; but as it departs 
very slightly in one or two other respects from the Tapajos 
individual, [ have drawn my description entirely from the 
latter.

corp. 1% lin. 

Antenne rather short, the basal joints yellow, the others 
infuscate ; palpi very pale yellow. Head rather narrower 
than the elytra, between the eyes coarsely punctured but 
distinctly shining; a little excavate, with a shining carina 
along the middle. Thorax much narrower than the 
elytra, much longer than broad, very little rounded in 
front of the middle, and but little narrower at the base 
than in the middle; densely covered with a deep, trans- 
versely rugose sculpture. Elytra along the suture quite 
as long as the thorax, coarsely and closely punctured; the 
interstices near the suture rather broader than elsewhere. 
Hind body slender, but a good deal narrower at the apex 
than the base; the basal segment margined and finely 
carinate in the middle, the two following segments scarcely 
carinate, the segments rather closely punctured; the punc- 
tures on the ante-apical segments obsolete, the pubescence 
depressed, fine pale yellow. Legs slender, rather long, 
yellowish ; the femora and tarsi darker towards the apex. 

Tapajos ; a single female. 

Obs.—This species is very closely allied to the S. cog- 
natus, but its more slender form, the smaller and more 
shining area separating the eyes, and the more cylindric 
thorax, leave me no doubt that it is specifically distinct 
therefrom. At first sight it suggests, to any one acquainted 
with the European species, S. proditor or S. impressi- 
pennis. It may be well to give a detailed comparison with 
the S. proditor. Besides the brassy colour of its upper 
surface and the paler legs and palpi, S. cursitor has the 
head more excavate and the central elevation narrower, 
polished and impunctate. The thorax is much more 
cylindric, with deep transverse ruge for sculpture; the 
punctures of the elytra are deeper and rather coarser; the 
hind body is more slender and cylindric, the basal segment 
only distinctly though finely margined, and the same 
segment is finely carinate in the middle as in S. proditor, 
but the following segments are scarcely carinate; the 
punctures on the basal segment are not very dissimilar to 
those of S. proditor, but on the following segments they 
are more indistinct; the legs are about as long, but are

slender.

Antenne moderately long, yellowish, infuscate towards 
the extremity; palpi pale yellow. Head about as broad 
as the elytra, excavate between the eyes, and with a dis- 
tinct shining carina in the middle of the excavation. 
Thorax rather longer than broad, the sides in front of the 
middle distinctly rounded; the surface coarsely and closely 
punctured, the punctures somewhat confluent, so as to 
form transverse ruge. Elytra about as long as the thorax, 
deeply, densely and coarsely punctured. Hind body 
moderately broad, with the basal segment finely margined, 
and carinate at the base in the middle, the two following 
segments with less elongate carine; the segments rather 
closely punctured, the punctures much finer towards the 
apex than on the basal segment. Legs yellow; the femora 
and tarsi obscured towards the extremity. 

In the male the 6th segment of the hind body beneath 
is broadly impressed along the middle; each side of the 
impression towards the extremity 1s densely pubescent, and 
there is a notch on each side concealed by the pubescence ; 
the following segment bears an elongate narrow notch ; the 
4th and 5th segments are also a little flattened along the 
middle. 

Tapajos ; one male, one female specimen. 

Obs.—This species, at first sight, a good deal suggests 
our common European S. impressus: though closely allied 
in structure to S. cognatus and the neighbouring species, 
it is undoubtedly distinct from them all.

Antenne pitchy, not paler at the base, moderately long; 
3rd joint a little longer than 4th; club slender. Palpi 
pale yellow. Head with the eyes as broad as the elytra, 
distinctly excavate, and with a shining carina at the 
bottom of the excavation. Thorax rather narrow, but 
longer than broad, much narrower than the elytra; the 
sides distinctly rounded in front and narrowed at the base; 
the surface densely punctured, the punctures arranged so 
as to make the interstices assume somewhat the form of 
transverse ridges. Elytra rather narrow, quite as long as 
the thorax, densely and coarsely punctured. Hind body 
slender, the basal segment rather coarsely punctured, 
carinate in the middle at the base, and finely margined at 
the sides; the two following segments more indistinctly 
carinate in the middle, and more finely punctured ; the 
segments towards the extremity very finely punctured, and 
with a very fine, depressed pubescence. Legs slender, 
rather long, yellowish; the femora a little darker towards 
the extremity ; tarsi very slender, 4th joint quite simple. 

In the male the 5th segment of the hind body on the 
underside is broadly impressed along the middle before the 
extremity ; the 6th is still more deeply impressed, and has 
the edges of the impression a little raised, and furnished 
towards the extremity with a ridge of raised black 
pubescence; the 7th segment bears a very long and ex- 
tremely narrow notch.

allies here described by the dark basal joints of the an- 
tenne.

at all shining. Hind body narrowed towards the extre- 
mity; all the segments finely margined, the three or four 
basal ones finely carinate at the base in the middle; the

Kga ; a single female. 

Obs.—This species is about the size of S. incanus, but 
is a little more elongate in proportion to the width, the 
antenn and legs are longer and more slender ; the elon- 
gate basal joint of the front and other tarsi separate it 
abruptly from that species and its allies.

than its predecessor; 7th joint much broader than 6th, 8th 
smaller than the contiguous ones, 9th and 10th stout, but 
each longer than broad; 11th joint small, shorter than 10th. 
Palpi only moderately long, quite yellow. Head almost 
as broad as the elytra; the space between the eyes rather 
depressed, but almost even, very obsoletely bisulcate, 
evenly and densely punctured. Thorax rather longer than 
broad, a good deal narrower than the elytra; the sides 
much rounded in front of the middle, and a good deal 
constricted behind; it is densely and rugosely punctured 
and not shining. LElytra a little longer than the thorax, 
densely and coarsely punctured, quite dull. Hind body 
finely but distinctly margined, much acuminate, closely 
punctured; the punctures moderately coarse on the basal 
segments, quite fine on the penultimate one, 2—4 each

Tn the male there is a moderately large excision at the 
extremity of the ventral plate of the 7th segment; the 6th 
is flattened and slightly depressed along the middle, finely 
punctured and very delicately pubescent, and its hind 
margin is a little emarginate; the hind margin of the 5th 
segment is obscurely emarginate.

yellow. Head with the eyes very large, a little broader 
than the elytra; the space between the eyes is distinctly 
depressed, but obsoletely bisulcate, rather coarsely but not 
evenly punctured, with a small, shining, smooth space at 
the vertex in the middle. Thorax a good deal narrower 
than the elytra, a little longer than broad; the sides a good 
deal rounded in front, and distinctly narrowed behind the 
middle; it is coarsely, very densely and quite rugosely 
punctured, so as not to be shining. Elytra broad, scarcely 
longer than the thorax, very coarsely, densely and rugosely 
punctured, not shining. Hind body rather slender, with 
the sides finely but distinctly margined; it is rather coarsely 
and distinctly and not closely punctured; it is distinctly 
shining, and there are no carine in the impressions on the

elongate; the hind tarsus has the basal joint very long, 
quite as long as the three following together; the 2nd 
joint is also elongate, and about half the length of the 
basal one, the lobes of the 4th joint are elongate and 
slender. The under surface is shining and coarsely 
punctured.

Antenne pale yellow, elongate and slender, longer than 
head and thorax; 3rd joint more than twice as long as 2nd, 
and a good deal longer than 4th; joints of the club elon-

the extremities; the surface closely and rather coarsely 
punctured. Ely tra just about as long as the thorax, but 
a good deal broader; the sfenid Sei distinct, the ee 
slightly curved; the punctuation rather coarse, a little 
coarser than on the thorax, rather close. Hind body 
elongate and cylindrical, the basal segment finely mar- 
gined, each segment with a long white pubescence, which 
is most distinct on its basal portion ; ; the basal segments 
finely but distinctly, rather sparingly punctured, the apical 
ones quite finely and sparingly. ” Legs pale yellow, elon- 
gate, rather slender, the lobes of the tarsi broad. 

In the male, on the underside, the 7th segment of the 
hind body bears a deep, narrow notch; the “6th is more 
closely punctured and pubescent along the middle than at 
the sides; the 5th is depressed along the middle before the 
apex, the depression impunctate but scarcely shining; the

broad as the elytra; the front not excavate, but a little 
depressed on either side between the eyes and the middle 
part, which is shining and impunctate. Thorax a good 
deal narrower than the elytra, much longer than broad, 
cylindric, the sides nearly straight, a little narrowed 
towards the base and slightly towards the front; mode-

obscurely punctured, with a distinct, silvery, depressed, 
long pubescence ; its under surface finely and sparingly 
punctured. Legs very pale yellow, elongate and slender; 
the lobes of the tarsi broad. 

Tapajos ; a single female. 

Obs.— This species bears an extreme resemblance to 
S. ventralis, but is undoubtedly distinct; S. extensus is 
rather the more slender of the two, and has the thorax 
more cylindric and distinctly carinated along the middle ; 
it is best distinguished, however, by the punctuation of 
the hind body, which is finer than in S. ventralis, a differ- 
ence which is very easily perceived when the undersides 
are compared.

minent; they are black and shining, coarsely punctured, 
the punctuation at the base dense, more sparing at the 
apex; at the extreme base is some delicate white pubes- 
cence. Hind body eylindric, slender, only the basal 
segment margined, the four basal segments rather coarsely 
punctured, and with a white pubescence at the extreme 
base of each. Legs clear yellow. 

The male has a broad and deep excision on the ventral 
plate of the 7th segment of the hind body; the 6th seg- 
ment is a little depressed near the hind margin, and 
there finely punctured, the hind margin being distinctly 
emarginate. 

Pari; two individuals ($ and ), collected by Mr. 
Smith. 

Obs.—This species bears a great resemblance to S. ez- 
cisus and S. Pare; but it is more slender than S. excisus, 
and has the elytra more closely punctured, and the punc- 
tuation of the hind body considerably coarser. It is rather 
smaller than S. Pare, is blacker, and more finely punc- 
tured, and has the pubescence at the base of the abdominal 
segments distinct.

and thorax, pale yellow, with the three or four apical 
joints infuscate, the three apical ones distinctly thickened ; 
3rd joint more than twice as long as 2nd. Head with the 
eyes almost broader than the ely tra; the space between 
the eyes slightly alc almost even, rather coarsely 
and closely punctured, yet distinctly shining. Thorax 
elongate and narrow, yet distinctly contracted behind the 
middle, so that the sides in the middle appear a little 
prominent; it is also slightly narrowed towards the front ; 
it is densely and coarsely punctured and yet shining. The 
elytra are rather narrow; they are scarcely longer than the 
thorax, their sides are a little rounded, the humeral angles 
quite prominent; they are coarsely and not closely punc- 
tured and shining, the punctures being fine and sparing 
at the hind margin; at the extreme base is a distinct 
white pubescence. The hind body is slender and eylin- 
dric, with only the basal segment margined; the four 
basal segments are distinctly, ‘but not coar rsely nor densely 
punctured, the apical ones obsoletely punctured ; each 
segment has at the extreme base a distinct, whitish 
pubescence. The legs are long and slender, very pale 
yellow; the tarsal lobes elongate and slender. 

In the male the ventral plate of the 7th segment has a 
very broad and deep incision ; the 6th seg ment is a little 
flattened towards the extremity and finely “punctured, and 
with a fine, pale pubescence; its hind margin is a little 
emarginate,

joints of about the same length. Palpi pale yellow. Head 
broad and short, about as broad as the elytra; the eyes 
separated by a broad space, which is distinctly depressed, 
and closely and coarsely punctured, but in the middle the 
punctures become sparing, so as to leave an irregular longi- 
tudinal shining space; on the underside the gene are 
very broad, and densely and coarsely punctured. Thorax 
much longer than broad, greatly narrower than the elytra, 
subcylindric; very slightly rounded at the sides, very

Palpi elongate, very pale yellow. Head with the eyes 
large, rather smaller than the elytra, distinctly excavate ; 
at the bottom of the excavation with a smooth, carina-like 
space. Thorax much longer than broad, subcylindric, but 
distinctly narrowed towards the front, and a little towards 
the base; shining brassy, with fine, pale hairs; coarsely, 
deeply and rather closely punctured. Elytra quite as long 
as the thorax, with the shoulders well marked and _pro- 
minent; coarsely, deeply and closely punctured, shining 
brassy, with a fine, pale, scanty pubescence. Hind body 
cylindrical, not margined, shining, sparingly, moderately 
coarsely punctured, with a fine, pale, elongate pubescence. 
Legs yellow, rather long; 4th joint of tarsi bilobed, the 
lobes rather long and narrow. 

The male characters are extraordinary: the hind legs 
are deformed; the femora are incrassate, the lower margin 
thickened near the middle, abruptly contracted near the 
base ; the tibixw are also thickened, and furnished near the 
middle with an angular prominence on their inner face, 
and below this prominence the inner face is partly sliced 
off; the basal joint of the tarsus is also distinctly dilated. 
On the underside of the hind body the basal segment has 
the hind margin thickened in the middle, but much emar- 
ginate, so as to form a broad notch, with rather prominent 
edges; the next segment has a smaller but shining notch, 
the 4th and 5th segments are also shining in the middle, 
in front of the hind margin ; the 6th is broadly emarginate, 
and the 7th is emarginate at the extremity, the emargination 
being continued forwards as a narrow, deep fissure.

closely punctured, except on the elevation. Thorax rather 
longer than broad, much narrower than the elytra, the 
basal portion distinctly contracted, and the sides narrowed 
towards the front; the surface closely and moderately 
coarsely punctured, with a small spot behind the middle 
free from punctures. Elytra largely developed, much 
longer and broader than the thorax, slightly depressed 
within the prominent shoulders, rounded and contracted 
towards the extremity, densely and coarsely punctured. 
Hind body broad at the base, and gradually narrowed 
towards the extremity; rather closely and moderately 
coarsely punctured, with a fine, distinct, depressed pubes-

Antenne only moderately long, pitchy, with the two 
basal joints yellow, and the following ones intermediate 
in colour; 3rd joint a good deal longer than 4th. Palpi 
elongate, yellow, the last joint dusky yellow. Head broad, 
but narrower than the elytra, only sparingly punctured, a 
broad space in the middle being quite smooth and even, 
outside this the punctures are but sparing ; the front is 
not excavate, but there is an impression on each side of 
the smooth central place; the antennal tubercles are very 
small, Thorax about as long as broad, much narrower 
than the elytra, a good deal broader in the middle than at 
the front and base; coarsely but rather sparingly punc- 
tured, the punctures most numerous near the front margin; 
a broad space on the middle impunctate. LElytra broad, 
the shoulders prominent, rather longer than the thorax, 
coarsely but sparingly punctured. Hind body broad at 
the base, but much narrowed towards the extremity; seg- 
ments 2—5 transversely depressed near the base in the 
middle, and a little contracted at the sides; rather

sparingly but coarsely punctured, the apical segments with 
only sparing and fine punctures. Legs dark yellow; tarsi 
rather long, with the lobes broad. Genz coarsely and 
rather closely punctured; underside of hind body very 
coarsely punctured. 

Tapajos; a single individual, which is I believe a female. 


24. Stenus parviceps, n. sp. (Sect. II. B, Er.) Niger,

femoribus tibiisque basi quam apice dilutioribus ; capite 
thorace vix latiore, bisulcato; elytris thorace longioribus, 
crebre fortiter punctatis; abdomine apicem versus angus- 
tato, crebre fortiter punctato. Long. corp. 2 lin. 


Antennz moderately long, yellow, with the club darker ; 
3rd joint a good deal longer than 4th. . Palpi yellow, the 
apical joint darker than the preceding one. Head much 
narrower than the elytra, and scarcely broader than the 
thorax, not excavate, but distinctly bisuleate ; the surface 
irregularly punctured, as when viewed from the front, the 
middle and some spaces near the eyes appear like shining 
spots. Thorax scarcely longer than broad, greatly nar- 
rower than the elytra, the sides not rounded but a little 
narrower at the base than in front; the surface coarsely, 
moderately closely punctured, the punctures absent from 
a very small space behind the middle. Elytra much 
longer and broader than the thorax, the shoulders rec- 
tangular and a little elevated, coarsely and closely but not 
densely punctured. Hind body a good deal narrowed 
towards the extremity, rather coarsely punctured; the 
punctures on the apical segments much finer than at the

fuscate towards the extremity; tarsi infuscate-yellow: 
under surface deeply, coarsely and densely punctured, 
opaque and with the white pubescence elongate and con- 
spicuous. 

The male on the underside exhibits a notch at the ex- 
tremity of the 7th segment; it is, however, much con- 
cealed by the dense, fine, elongate, pale pubescence, which 
covers the middle of the segment; the 6th segment is also 
densely pubescent along the middle, and its hind margin 
is slightly notched at the extremity.

378 Mr. D. Sharp’s Contributions to the 


Amazons; a single individual, without more special 
locality. 

Obs.—I have also a specimen from Ega, which I believe 
to be merely a variety of this species; the chief difference 
it exhibits from the individual above described consists in 
the absence of any smooth space on the thorax. 


25. Stenus proximus, n. sp. (Sect. II. B, Er.) Niger, 
supra nitidus, parcius albido-pubescens, antennis palpisque 
testaceis, apice infuscatis; pedibus infuscato-rufis, femoribus

latiore, bi-impresso; elytris thorace longioribus, crebre 
fortiter punctatis; abdomine crebre fortiter punctato. 
Long. corp. 14 lin. 


Antenne reddish with the club, dusky; palpi yellow, 
but with the front half of the last joint distinctly darker. 
Head small, not excavate, with two impressions between 
the eyes, which can scarcely be called sulci, as they do not 
reach the vertex, and are also abbreviated in front by the 
well-marked antennal tubercles ; only sparingly punctured, 
the more elevated portions appearing as smooth spaces. 
Thorax much narrower than the elytra, rather longer 
than broad, slightly curved at the sides towards the front, 
coarsely and rather closely somewhat irregularly punc- 
tured. LElytra longer than the thorax, distinctly impressed 
within the prominent shoulders, coarsely but not closely 
punctured. Hind body rather coarsely and moderately 
closely punctured, much more finely at the extremity than 
on the basal segments. 

Amazons (probably Tapajos ; a single male. 

Obs.—This species is excessively closely allied to S. 
parviceps, and differs therefrom only in slight characters ; 
it is a little smaller than S. parviceps, and has the antennz 
distinctly shorter ; the sulci on the head are less distinct, 
being more fovea-like ; the thorax is slightly narrower, the 
elytra are rather shorter and rather more coarsely and less 
closely punctured; the punctuation of the hind body is 
not quite so coarse and deep. The male characters seem 


scarcely to differ. 


M&GALOPS. 
Many points of the structure of these remarkable insects 
remain to be ascertained, before the position and affinities 
of the species can be satisfactorily decided on. Erichson 


Staphylinide of the Amazon Valley. 379 


describes the antennz as ten-jointed. I find them, how- 
ever, to be certainly eleven-jointed, the basal joint being 
short and very stout, and much concealed by the prominence 
above its point of insertion. Erichson has also described 
the tarsi as five-jointed, and the 4th joint to be minute. 
On inspection, however, the tarsi appear at first to be only 
four-jomted, but a more careful examination reveals the 
fact that the tarsi are really five-jointed, and that the 
4th joint is not minute, but consists of a very small basal 
and articular portion, to which are attached two long 
slender lobes, which are so closely applied to the 5th joint 
as only to be detected by bending or lifting up the ter- 
minal joint. 

Nothing is known as to the structure of the labrum, 
which is quite invisible in the species. It is probable, 
however, that it is concealed under the largely-developed 
horny clypeus, and that it is moveable; and that the two 
long spines which appear to proceed from the front of the 
clypeus are in reality appendages from the labrum. The 
sexual characters have hitherto escaped observation. I 
have pointed them out in the following description of 
M. spinosus, but should add that, though in M. spinosus 
the antenne are similarly formed in the two sexes, in some 
of the other species there is a remarkable sexual disparity 
in the structure of the apical joints. 

Seven species of the genus have already been described : 
two from Northern America, three from South America, 
one from Australia and one from South Africa. The 
species, however, are undoubtedly more numerous in 
South America than elsewhere, for I have thirteen species 
from thence in my collection, while the only other species 
I have seen is the Australian one. 


1. Megalops spinosus, n. sp. Niger, nitidus, antennis

Antenne yellow, darker towards the extremity, with 
the club fuscous; 8rd jomt twice as long as 2nd, 4th 
about as long as 2nd; 5—7 each shorter than its pre- 
decessor; 8th small, 9th a good deal broader than 8th, 
bead-like ; 10th rather strongly transverse, 11th moderately 
large, slightly broader than 10th, as long as 9th and 10th 


380 Mr. D. Sharp’s Contributions to the 


together, obtusely pointed. Palpi yellow. Head broad; 
the eyes very large, even broader than the elytra; the 
clypeus armed in front with two very elongate, pitchy- 
yellow spines, which are ciliated internally, the horny 
clypeus deeply impressed and separated by a straight 
depressed line from the front; the front with elev ations 
and depressions so placed as to form a central elevated 
space, surrounded, except at the summit in the middle, by 
a broad, irregular depression; also with a fine depression 
along the inner margin of the eyes, in which are a few 
punctures. Thorax broad, with four transverse furrows 
in which are large punctures; the first of these grooves is 
placed near the front margin, whose course it follows; the 
second extends in a near ly straight line across the fone 
so that it is nearer to the front one at the sides than in the 
middle,—it can scarcely be said to be interrupted in the 
middle; the third furrow is the broadest and is distinctly 
interrupted in the middle, the hinder one is placed close 
to the base; the sides appear a little waved and have two 
angular projections near the front. Scutellum emarginate- 
truncate at the apex, bearing two fover. Elytra “proad, 
broader than long, about as long as the thorax, deeply 
impressed at the base for the thorax; each near the 
shoulder with an oblique stria, sharply limited on the 
inner but not on the outer side. Legs yellow; coxe 
castaneous. 

Ega; two specimens, both of which appear to be 
females. 

Obs.—Besides the two females above described, I have 
also two males of this species, which I obtained from the 
collection of Mr. E. W. Janson, where they were labelled, 
* Para, Brazil.” These two males have the ventral plate 
of the 7th segment of the hind body slightly emarginate 
on each side the middle at the extremity: and the pre- 
ceding segments are slightly flattened along the middle, 
and furnished there with a very fine and scanty short 
pubescence. The structure of the antennz is quite the 
same as in the females.

more obscure; joints 6—8 small, 9th transverse, 10th 
much broader than 9th, strongly transverse, 11th rounded, 
rather large. Palpi yellow; clypeus with two elongate 
spines, its front with an emargination on each side. Head 
broad and short, with impressions placed much as in M. 
spinosus, but the depressions formed as it were by con- 
fluent punctures. Thorax with very coarse punctures 
covering the greater part of its surface; a series behind 
the front margin, a second series separated from the front 
one by a rather elevated space; along the middle with 
a third, broad, confused, double series, interrupted in the 
middle, also with a basal series, and with additional 
punctures (not extending across the middle) in front of 
the basal series. Elytra broad and short, the sutural stria 
very deeply impressed at the base, across the middle with 
a deep oblique impression, and near the inner edge of this 
with two obsolete punctures. Hind body with the im- 
pressions at the base of the segments large and distinct. 
Legs yellow; cox darker. 
Villa Nova; a single female, found under chips. 


Osorius. 


About eighteen species of this genus have been described, 
eight from warm America, one from North America, and 
the others from the warm parts of the Old World. I here 
describe seven Amazonian species, and though this seems 
a considerable addition to the South American species, it 
is, In comparison with the undescribed species, but small ; 
for I find the specimens of the genus from South America 
extant in my own collection must be referred to about 
forty species. The genus is one of excessive difficulty to 
the student, from the extreme resemblance of the species 
to one another; and it is not until careful examinations 
and comparisons are made, that the characters distin- 
guishing the species from one another are seen and appre- 
ciated. ‘The structure of the species indicate very sedentary 
habits; the cohesion or attachment of the different parts 
of the body together is but slight, so that these insects 
drop to pieces in our collections with only too great ease. 
It has been observed that some of the species live in 
burrows in decaying wood, but it is not indicated whether 
they follow the borings of other insects, or make the 
burrows for themselves. The almost complete absence 
of external characters to distinguish the sexes is worthy of

remark, as is also the simple but peculiar form of the 
edeagus, this organ scarcely varying, moreover, in the 
different species.

Head with the surface coriaceous, and sprinkled with 
distinct punctures; the clypeus emarginate in front, so 
that the anterior angles form blunt projections, but not at 
all spinose, and also obtusely prominent in the middle ; 
the temples, over and behind the eyes, with coarse distinct 
ruge, and some small rough elevations. Thorax much 
broader than long; the sides much narrowed behind and

distinctly sinuate in front of the hind angles, which are 
distinct and nearly right angles, but a little obtuse; the 


sides distinctly impressed i in front of the hind angles; so as 
to make the lateral margin appear strongly raised there ; : 
the surface entirely coriaceous, but more finely so than the 
head, and with distinct though sparing punctures, and 
with a short, fine channel alone the middle. Elytra dis- 
tinctly longer than thorax, entirely covered with shallow 
irregular ruge ; on the underside the prominence of the 
proster num is ‘very marked, the mesosternum distinctly 
carinate in front of the coxe. The hind body with very 
few sete, the apical segment coarsely strigose, especially 
at the sides, and with strongly marked tubercles.

Obs.—TVhis is the largest species of the genus yet 
known ; the structure of the front of the head readily dis- 
tinguishes it from O. ater.

Clypeus almost straight in the middle in front, but with 
the angles thick and prominent, but not at all spinose. 
Head shining, rather sparingly but distinctly punctured, 
the antennal tubercles well marked, and the eyes distinctly 
prominent; the punctures are wanting in front of the 
vertex, and are wanting about an irregular longitudinal 
space along the middle. Thorax slightly longer than it is 
broad at the base, a little narrowed from the front to the 
base; the surface shining, sprinkled with punctures like the 
head, indistinctly channelled along the middle; the hind 
angles distinctly obtuse, but not far from right angles. 
Elytra a little longer than the thorax, shining, with indis- 
tinct rugulose impressions and elongate punctures. Hind 
body shining, rather slender, impunctate above; on the 
underside the 7th segment bears a large smooth impression 
in the middle at the ‘extremity , on each side of which it is 
sparingly sculptured, and furnished with scanty hairs, the 
punctures quite at the side forming obscure distant rugee ; 
the 6th segment coarsely punctured, the punctures rather 
close on the middle; the preceding segments also with 
coarse punctures on the middle.

Obs.—This species is closely allied to O. nitens, but is 
rather smaller and distinctly more slender; the clypeus i is 
not prominent in the middle, and the antennal tubercles 
are more distinct; it is possible that the paler colour may 
be only the result of the immaturity of the individual de- 
scribed.

Clypeus emarginate in front, the angles not produced. 
Head rather coarsely and moderately closely punctured, 
with a smooth space in front of the finely-punctured 
vertex ; black and shining, not coriaceous. Thorax about 
as long as it is broad at the base, only a little narrowed 
from the front to the base; the hind angles distinctly 
obtuse, but not far from right angles; the surface shining 
black, rather coarsely and not ver y sparingly punctured, 
and with traces of a short channel on the middle. E lytra 
a little longer than the thorax, shining, with a distinct 
but neither dense nor deep sculpture, consisting of indefi- 
nite rug, and sparing, ill-defined, elongate “punctures. 
Hind body black; above sparingly sprinkled with obsolete 
punctures, beneath with the 7th segment in the middle 
coarsely punctured, and bearing a fine elongate pubes- 
cence, the punctures at the sides more sparing, but coarse, 
and passing into shallow ruge; 6th segment coarsely 
punctured about the middle, and the preceding segments 
also with some coarse punctures about the middle. 

Ega; a single male. 

Obs.—This species at first sight exactly resembles 
O. nitens, but the clypeus is not prominent in the middle ; 
the head and thorax are more distinctly punctured, and 
the punctuation of the hind body is different.

with the front angles distinctly prominent; surface of 
head shining, rather coarsely punctured, with a smooth 
space in front of the vertex; over the eyes the punctures 
become strigose. Thorax about as long as it is broad in 
front; the sides gently narrowed to the base, the angles 
obtuse, and, owing to the base being distinctly curved 
_ near the angles, appearing somewhat rounded; the surface 
shining, rather coarsely and not very sparingly punctured. 
lilytra scarcely longer than the thorax, shining, with rather 
coarse, elongate, distinct punctures. Hind body above 
with a few obsolete punctures, which are most numerous 
and most visible on the 6th and 7th segments; these seg- 
ments are besides very finely strigose, so as not to be 
shining. The sculpture of the ventral plate of the 7th 
segment similar to that on the dorsal plate, viz., some 
coarse but obsolete, sparing, elongate punctures, the sur- 
face besides being finely and densely strigose, so as to 
be opaque; the 6th segment beneath is also scarcely 
shining, and with some coarse, scattered punctures. 
Mesosternum strongly carinate. 

St. Paulo ; a single individual, which I consider to be 
a female. 

Obs.—This species is remarkable by reason of the com- 
parative large development of the upper tooth on the 
right mandible.

which pass into rugz over the eyes, and are wanting in 
front of the vertex. Thorax about as long as it is broad 
in front, the lateral margin fine throughout; the sides 
gently narrowed towards the base, slightly sinuate in front 
of the hind angles, which are therefore distinct, and are 
obtuse; the surface coriaceous, and sprinkled with rather

punctures. Hind body shining above; the 6th and 7th 
segments with shallow, rather sparing punctures; sculp- 
ture of the 7th segment on the under side almost similar 
to that of the upper side; 6th with sparing coarse punc- 
tures. Legs reddish, with the femora pitchy red. 

St. Paulo; a single individual, which I consider to be a 
female. 

Obs.—This species is closely allied to O. solidus, and 
has the mandibles similarly formed, but is readily distin- 
guished by the different sculpture.

Antenne red; 7th joint abruptly larger than the pre- 
ceding ones. Clypeus nearly straight in front, the angles 
very slightly prominent ; surface of head shining, coarsely 
punctured, the punctures wanting along the middle and 
at the vertex. Thorax about as long as broad, coarsely, 
deeply and rather closely punctured, with a sharply- 
defined longitudinal space along the middle impunctate ; 
the sides slightly narrowed from the front to behind the 
middle, and thence more abruptly to the base; the lateral 
margin very fine, the hind angles obtuse and indistinct. 
Elytra rather longer than the thorax, coarsely and mode- 
rately closely and deeply punctured. Hind body above 
densely punctured, and with a distinct, rough, pale pubes- 
cence; beneath coarsely punctured, but more sparingly 
than on the upper side, and therefore more shining. Legs 
red; hind tibiz slender, bearing three spines. 

Ega; three individuals. 

Obs.—This species at first sight greatly resembles the 
North American O. latipes, but it is considerably smaller, 
and may be at once distinguished by the larger and more 
convex eyes. Laporte has described a species about 
this size from Columbia; but the few words of his de- 
scription (Osorius pygmeus, Etudes Ent. p. 130) are 
so meagre as to render the identification of his species 
extremely difficult. 


Staphylinide of the Amazon Valley. 387 


HoLoTrRocHus. 


Six species are at present placed under this. generic 
name, five of which inhabit tropical America, the other 
being found in Madagascar. I here describe six other 
species ; of these the H. durus appears to be somewhat 
allied to the H. volvulus figured by Erichson. The 
species I have described as H. syntheticus differs from 
the HZ, durus by some structural peculiarities, among the 
more interesting of which is the formation of the apical 
segments of the hind body. Attention being paid to this 
character and to the facies of the species an affinity with 
Lispinus is strongly suggested. The other two species, 
viz., H. pubescens and H. subtilis, when I first examined 
them, at once suggested to me a relationship with an insect 
which has been one of the unsatisfactory ones in the clas- 
sification of the Staphylinide, viz., Phleocharis subtilis- 
sima; and, on comparing the Hl. pubescens with P. sub- 
tilissima, | find such a prima facie resemblance in the 
structure of the thorax and middle body as to lead me to 
think that the natural connection of Phlwocharis subtilis- 
sima will be found to be with this group of Holotrochus. 
Indeed, I may say, the variety of facies and of certain 
structural characters which exist in Osortus and its allies 
and in these species of Holotrochus, suggest to me that 
the accurate study of these insects will be found to suggest 
an improved arrangement of some of the Prestini, Oxy- 
telint and Phleocharini; and I shall not be at all surprised 
if it be ultimately considered that we have here preserved 
for us sume of the more primitive forms of the Staphy- 
linide. It will not improbably be suggested that I ought 
to have established a new genus for H. syntheticus and 
H. pubescens, but after the examination of several un- 
described intermediate American forms which exist in my 
collection, I have considered it better not to do so. As 
regards the two last species here described, viz., H. clavipes 
and H. Fauveli, I think it highly probable that they will 
prove to be closely allied to Anceus megacephalus, Fauvel. 
In establishing the genus Anceus, M. Fauvel, to dis- 
tinguish it from the Oxzytelini, pointed out the hidden and 
retractile 7th segment of the hind body. The structure 
of that segment is, however, subject to so much variation 
both in the Ozytelini and Piestini (as they are at present 
limited) that this point throws but little light on the 
affinities of M. Fauvel’s insect. M. Fauvel considered 

cc2 


388 Mr. D. Ms Contributions to the 


the Anceus megacephalus to be most allied to Lispinus ; 
but the two insects I have described as H. clavipes and 
H. Fauveli differ in a highly important respect from the 
species of Lispinus, inasmuch as they have the front cox 
exserted and not covered or separated by any process 
similar to that which is so conspicuous in Lispinus. I 
must not be understood as implying that the two insects 
I here allude to will be ultimately considered congeneric 
with the other Holotrochi here described, for I consider 
that in the present state of our knowledge of these Staphy- 
linide it is quite impossible for us to decide where there 
really occur those separations and gaps between species 
which warrant the formation of genera. 


1. Holotrochus durus, n. sp. Niger, glaber, nitidus, 
parce sed distincte punctatus, antennis piceis, pedibus 
piceo-rufis. Long. corp. 34 lin. 

Mas: abdomine segmentis ventralibus 6 et 7 profunde 
impressis. 


Antennz stout, shorter than head and thorax, insertion 
near the front of the eye in a large cavity, greatly over- 
lapped by the side of the clypeus; Ist joint much con- 
cealed, and thick, 2nd joint small, 3rd a good deal longer 
than 2nd, dilated towards the extremity; joints 4—10 
transverse, llth rather narrower than 10th, obtusely 
pointed; the six basal joints are pitchy, the others red, but 
this colour is much obscured by the pubescence. Head 
much narrower than the thorax; clypeus greatly rounded 
in front; the surface shining and rather finely and sparingly 
but quite distinctly punctured. Thorax scarcely so long 
as broad, almost broader than the elytra; the sides a little 
rounded towards the front, nearly straight behind the 
front, and thence only very slightly narrowed to the base ; 
the hind angles almost right angles; the surface is shining 
black, rather sparingly but distinctly punctured; it is 
transversely convex, the sides margined, the base closely 
applied to the elytra and not margined; near the hind 
angles are traces of a longitudinal impression. Elytra 
shghtly longer than the thorax, with a well-marked 
sutural stria moderately finely and sparingly punctured, 
with an indistinct longitudinal series of four or five larger 
punctures along the middle. Hind body with segments 
2—5 of equal width, each segment smooth in the middle, 
obscurely punctured at the sides, less shining than the front

parts of the body. Legs dark reddish. Prosternum pro- 
minent, but not carinate in the middle in front; meso- 
sternum with a prominent piece between the middle coxa, 
which are therefore distinctly separated; metasternum 
smooth, shining black, deeply channelled. In the male 
the ventral plate of the 6th segment bears a large and 
deep, almost horseshoe-shaped impression, which is sur- 
rounded by a kind of margin, and has a peculiar granular 
pubescence along its sides; the 7th segment bears a similar 
but more elongate impression, the bottom of which is 
covered by the peculiar granular pubescence; the apical 
portion of this segment is produced in the middle as a 
broad lobe; the punctures on the under face of the hind 
body in this sex are coarser than in the female. 

The female lacks the impressions described above, and 
the produced lobe of the 7th segment is narrower and 
more pointed. 

Amazons; three females, one male. One of these 
specimens is indicated as being from Ega. 

Obs.—The structure of the 8th segment of the hind 
body and of the «zdeagus in this species are peculiar; the 
dorsal and lateral plates of the former are formed much as 
in Osorius, but each lateral plate bears a pencil of elongate 
delicate hairs; the ventral plate appears to be altogether 
absent; the wdeagus is complicated in its structure and 
laterally asymmetrical, and the missing ventral plate of 
the 8th segment appears to me to be attached to one side 
of the «edeagus as a lateral appendage thereof.

Antenne yellow; 1st joint rather long and stout, not 
much concealed by the clypeus, 2nd and 3rd joints sub- 
equal, rather slender, 4, 5 and 6 small, not differing much 
from one another, the 6th hardly so long as broad; joints 
7—11 much larger than the preceding ones, 7—10 
scarcely differing from one another, each distinctly trans- 
verse, 11th scarcely so broad as 10th, obtusely pointed. 
Head small, much smaller than the thorax; the eyes pro- 
minent; the clypeus rounded; the surface pitchy, very

shining, rather sparingly but distinctly punctured, the 
vertex smooth. Thorax strongly transverse, the sides 
slightly curved, about as broad at the hind as at the front 
angles; the hind angles sharply-marked right angles, 
much more elevated than the front ones; the lateral 
margin very fine; close to each hind angle is a large broad 
and deep impression; the surface is shining, and it is 
distinctly, not closely punctured, the punctures are most 
numerous about the middle, nearly wanting at the sides, 
and there is a very indistinct longitudinal space along the 
middle smooth. Elytra much longer than the thorax, 
very shining, rather coarsely and sparingly punctured, 
each with a well-marked sutural stria. Hind body elongate, 
conical cylindric, being much narrowed towards the ex- 
tremity; the surface nearly opaque, being finely pubescent, 
and covered with a peculiar obsolete punctuation. Legs 
reddish, the tibiz bearing hair-like spines, which are most 
distinct on the intermediate legs. Prosternum short, with 
a very fine tubercle in front of the cox; mesosternum 
with a sharply-elevated laminar carina; metasternum with 
a short, coarse channel, shining, sparingly punctured. 

In both sexes the ventral plate is produced at the 
extremity, so as to form an angular projection; this pro- 
jection is more elongate and the angle at its extremity 
more acute in the female than in the male. 

Tapajos ; five individuals. 

Obs.—This species departs widely in its facies from 
H. durus, and in the structure of its hind body approaches 
to Lispinus; the dorsal plate of the 8th segment has not 
the peculiar box-like structure found in H. durus and in 
the species of Osorius; the ventral plate appears to be 
absent as in Hf. durus, the under face of the segment 
being formed by the folded lateral plates, which are ample, 
and have quite lost the very hard, spinous character of the 
same parts in //. durus.

the preceding ones, 7—10 rather strongly transverse; 11th 
joint as broad as the 10th, obtusely pointed. Head much 
narrower than the thorax, dull reddish; punctuation very 
indistinct, but with a well-marked, fine, rather long, 
yellowish pubescence ; eyes rather prominent. Thorax as 
broad as the elytra, rather strongly transverse, very slightly 
curved at the sides; the front angles more depressed than 
the hind ones, the base a little emarginate, so that the 
hind angles project backwards ; the surface clothed with a 
fine, dense pubescence, but with scarcely visible sculpture. 
Elytra a good deal longer than the thorax, with similar 
pubescence and obsolete sculpture. Hind body cylindric, 
scarcely narrowed till the 7th segment, which is very 
retractile. Legs reddish, the tibize with fine spines, which 
are most. distinct on the intermediate legs. 

Tapajos ; ten individuals. 

Obs.—Notwithstanding the great difference in appear- 
ance between this species and the preceding (//. synthe- 
ticus), they appear to be structurally closely allied. In 
certain individuals of 7. pubescens the ventral plate of the 
7th segment of the hind body is somewhat prolonged and 
acuminate in the middle; judging from what is the case 
in H. syntheticus, I consider these to be females. 


4. Holotrochus subtilis, n. sp. Ferrugineus, subtiliter 
sat dense pubescens, subnitidus, obsolete punctatus ; pro- 
thorace transverso, angulis posterioribus fere acutis. Long. 
corp. 14 lin. 

This species is extremely closely allied to H. pubescens, 
but is readily enough distinguished, on comparison, by the 
much shorter and more inconspicuous pubescence and the 
less opaque surface; it is also a little smaller, and has the 
antenne a little shorter; in other respects it appears 
scarcely to differ from H. pubescens. 

Ega; three individuals.

spicuous, crossed in repose. Head elongate; the front 
angles of the elongate clypeus rounded, the middle slightly 
emarginate; on each side, near the front, is a large depres- 
sion; the surface very finely strigose, so as to be but little 
shining, and with a few fine, distant punctures. Thorax 
about as long as broad, distinctly narrowed towards the 
base, but ae the aude not curved; the lateral margin 
excessively fine, and only distinct on the posterior part ; 
close to each hind angle is a rather large, but not sharply 
defined depression ; the hind angles are dbbask: the sculp- 
ture of the surface is similar to that of the head, and there 
is a fine, abbreviated channel along the middle. Elytra 
rather longer than the thorax, and about as ‘broad as it is 
at the base, with a well-marked sutural stria; the sculp- 
ture similar to that of the head and thorax, but the scat- 
tered punctures excessively fine and indistinct. Hind body 
almost without sculpture. Legs short, pitehy ) yellow, the 
hind femora extremely stout, the four basal joints of the tarsi 
very short. Under surface smooth and without sculpture.

from one another, the 7th and 8th, however, distinctly 
transverse; 9th and 10th distinctly broader than the pre- 
ceding ones, rather strongly transverse; 11th obtuse at 
the extremity. Head elongate, with the mandibles not 
large but prominent; the ely peus with the front angles

BLEDIUS. 


The species of this well-known genus here described 
are seven in number, and suggest no special remark; only 
one species was found by Mr. Bates, the other six being 
discovered by Dr. Trail. Only three or four species have 
been previously described from South America, yet it is 
very probable that the genus is numerously represented 
there, for these insects. are very retiring in their habits 
and little likely to come under the notice of collectors, 
except special search be made for them. 


1. Bledius albidus, Nn. sp. Pallide testaceus, obsolete 
punctatus, subnitidus ; capite castaneo, bituberculato. 
Long. corp. 13 lin. 

Antenne very pale yellow, slender 5 basal joint as long 
as the three or four following ones together; 2nd more 
than twice as long as 3rd; the four or five apical joints 
stouter than the others, each of them about as long as 
broad. Mandibles elongate, their upper edge with a tooth 
near the base, and beyond the middle with a long spine- 
like tooth directed forwards and upwards. Head darker 
than the rest of the insect, castaneous, with the eyes black; 
the clypeus much deflexed; close to the eye on each side 
is a prominent tubercle; the punctuation is quite obsolete. 
Thorax a little narrower than the elytra, not so long as 
broad, nearly straight at the sides, with the hind corners 
oblique; it is almost white, except that the fine depressed 
basal margin is black in the middle; it is extremely finely 
channelled, and finely and obsoletely punctured, Elytra 
short, but a little longer than the thorax, pale yellow, finely 
and indistinctly punctured. Hind body pale yellow, im- 
punctate. Legs very pale yellow; the front tibie very 
broad below the middle, abruptly contracted at the apex. 

Jurua; a series of individuals, captured by Dr. Trail on 
the 3rd November, 1874. 

Obs.—This very distinct little species can be readily 
identified by the perpendicular front part of the head. I 
do not observe any indications of sexual differences.

nearly straight at the sides till behind the middle, and 
thence a good deal narrowed to the base, so that the hind 
angles are very obtuse; it is not quite so long as broad,

tatis; abdomine impunctato. Long. corp. vix 14 lin. 

Antenne yellow, rather short, gradually thickened from 
the 3rd joint to the extremity ; joints 6—10 rather strongly 
transverse. Mandibles reddish, slender and curved, only 
moderately long, unarmed. Head black, with the eyes 
very convex, without sculpture and quite unarmed. Thorax 
reddish, only slightly shining, much broader than long, 
nearly as broad as the elytra, ‘the hind angles very obtuse ; ; 
it has a very fine channel along the middle, and is indis- 
tinctly and rather sparingly punctured. Elytra distinctly 
longer than the thorax, yellow, with the sutural portion 
broadly infuscate; they are finely and rather closely punc- 
tured, the hind margin of each separately much rounded. 
Hind body quite impunctate. Legs pale yellow, short ; 
the tibiz rather slender.

capite nigricante; thorace vix transverso, obsolete canali- 
culato, parce obsoleteque panei elytris crebre subtiliter 
punctatis. Long. corp. § lin. 

Antenne yellow, rather stout; all the joints from 3—10 
short, and each stouter than its predecessor, so that the 
penultimate ones are strongly transverse. Mandibles not 
elongate. Head black, without distinct punctuation, 
quite unarmed, with the eyes very convex. Thorax 
slightly narrower than the elytra, only a little broader 
than long, the hind angles quite rounded; it is yellowish 
and distinctly shining, “only sparingly and very obsoletely 
punctured, and with a very obsolete channel along the 


396 Mr. D. Si,’s Contributions to the 


middle. FElytra distinctly longer than the thorax, yel- 
lowish, finely and moderately closely punctured. Hind 
body yellow, impunctate. Legs yellow, only moderately 
stout. 

Rio Madeira; two individuals, captured by Dr. Trail 
25th May, 1874. They were attracted by light. 


6. Bledius similis, n. sp. Fusco-testaceus, capite ab- 
dominisque apice summo nigricantibus, pedibus pallidis ; 
prothorace subtransverso, obsolete punctato, subtiliter 
canaliculato, angulis posterioribus sinuatis; elytris sub- 
tiliter sat crebre punctatis. Long. corp. 1 lin. 


Antennz yellowish; all the joints from 3—10 short, 
and each distinctly stouter than its predecessor, so that 
though the 3rd joint is both short and slender, the penul- 
timate ones are rather strongly transverse. Head black. 
Thorax reddish, blackish towards the front margin, dis- 
tinctly shorter than broad, only slightly narrower than the 
elytra, sparingly and indistinctly punctured, channelled 
along the middle; it is a little shining: the sides are 
nearly straight, till near the hind angles, when they are a 
good deal narrowed, in such a way as to make the hind 
angles appear a little sinuate. "The elytra are rather 
narrow, a good deal longer than the thorax, of a dirty- 
yellowish colour, finely and indistinctly punctured. The 
hind body is yellowish and impunctate, the extreme apex 
a little blackened. The legs are pale yellow, rather 
slender. 

Rio Purus; a single individual, found by Dr. Trail on 
the 25th October, 1874. 

Obs.—This minute species resembles extremely the 
B. muticus, but has the thorax differently formed. 


7. Bledius modestus,n.sp. Piceus, elytris dilutioribus, 
antennis pedibusque testaceis; prothorace latitudine haud 
breviore, lateribus rotundatis, canaliculato, sat evidenter

% lin. 

Antennz yellow, short; all the joints from 3—10 short 
and each distinctly broader than its predecessor, so that 
the penultimate ones are rather strongly transverse. Man- 
dibles and palpi yellow, head nearly black, with the an- 
tennal tubercles rather strongly marked, and the eyes very 
convex. Thorax distinctly narrower than the elytra, as 


Stuphylinide of the Amazon Valley. 397 


long as broad, the sides a little rounded, and the base and 
hind angles rounded; it is of a pitchy colour and distinctly 
shining, with a channel along the middle, moderately 
closely but not very distinctly punctured. Elytra of an 
obscure-yellowish colour, distinctly longer than the thorax, 
finely and rather closely punctured. Hind body pitchy, 
curved at the sides and evidently contracted at the base ; 
it is shining and almost impunctate. Legs pale yellow, 
rather slender. 

Rio Madeira, a single individual found by Dr. Trail on 
the 25th May, 1874; it was attracted by light. 

Obs.—This is the smallest species of Bledius I have 
seen; it is closely allied to B. muticus and B. similis, but 
is rather more slender in form, and has thé sides of the 
thorax more curved. 


TROGOPHL@US. 


Five species of this genus are here described, and only 
one other was previously known from the Continent of 
South America; the genus is one of almost universal 
distribution, and likely to prove numerous in species even 
in the tropics. The paucity of species as yet known from 
South America is pretty certainly, therefore, only the result 
of neglect on the part of collectors; several species are 
known from Cuba, and species of the genus are numerous 
in Chili. 


1. Trogophleus mundus,n.sp. Niger, dense punctatus, 
pedibus testaceis, antennarum basi fusco-testaceo; elytris 
subtestaceis ; prothorace basi minus discrete bi-impresso. 
Long. corp. | lin. 


Antenne moderately long, a good deal thickened 
towards the extremity, blackish, the basal joint yellowish ; 
3rd joint shorter and more slender than 2nd; 4th joint 
small, 6—8 small and transverse, J—11 distinctly broader 
than the others. Palpi infuscate, the 3rd joint broad. 
Head nearly as broad as the thorax, the eyes large, and 
occupying nearly all the side of the head; antennal tuber- 
cles elongate and sharply elevated, the surface depressed on 
the inside of each, so that the front of the head bears two 
longitudinal impressions; the surface of the head very finely 
punctured, dull. Thorax a good deal narrower than the 
elytra, a good deal broader than long, much narrowed 
towards the base ; the surface densely punctured, and near 


328 Mr. D. SH¥P)’s Contributions to the 


the base with two indistinct impressions extending towards 
the hind angles, and with scarcely any traces ‘of longi- 
tudinal impressions. Elytra brownish, the base rather 
infuscate, densely and finely punctured, much longer than 
the thorax. Hind body black, very densely punctured, 
with a very fine, short, delicate, pale pubescence. Legs, 
including the cox, pale yellow ; ; middle coxve elongate, 
and separated by a very narrow space. 

Kga; a single individual. 

Obs.—This species, at first sight from its small size and 
comparatively narrow form, sugvests a comparison with 
our 7. corticinus and T. pusillus, but its structural cha- 
racters show it to be more nearly allied to T. obesus. A 
second specimen from the same locality has the palpi, the 
base of the antennz and the thorax paler in colour ; but 
I consider it probable that these differences are only the 


result of the immaturity of the specimen. 


2. Trogophleus breviceps, n. sp. _ Brevior, latiusculus, 
piceus, antennis, palpis, pedibus, abdominisque apice tes- 
taceis; capite brevi, lato; thorace fortiter transverso, 
longitudinaliter bi-impresso ; elytris subnitidis, minus 
dense punctatis. Long. corp. 14 hn. 


Antenne yellowish, longer than head and thorax; Ist 
joint very elongate, 3rd much more slender than 2nd, 
8th about as long as broad, 9th and 10th a little transverse. 
Head very short and broad, but a little narrower than the 
thorax, the eyes, however, leaving a distinct prominent 
space behind them at the sides; the antennal tubercles 
short, the surface dull and extremely finely punctured. 
Thorax a good deal narrower than the elytra, about twice 
as broad as long, distinctly narrowed towards the base ; 
the surface dull, extremely indistinctly punctured, with 
two distinct longitudinal impressions along the middle, 
which do not reach to the front, and near each side with a 
more indistinct broad impression. LElytra much longer 
than the thorax, neither altogether finely nor densely, but 
still indistinctly punctured, a little shining. Hind body 
broad, the apex yellowish; the segments indistinctly and 
sparingly punctured, and a little “shining. Legs bright 
yellow; under side of head and thorax obscure reddish ; ; 
middle coxze scarcely contiguous; under face of hind body 
densely and finely punctured, dull. 

Ega; a single individual.

3. Trogophleus latifrons, n. sp. Rufus, capite fusco- 
rufo; prothorace transverso, lateribus subdenticulatis, 
dorso minus distincte bi-impresso; elytris sat fortiter 
punctatis; abdomine obsolete punctato, apicem versus 
nitidulo. Long. corp. 14 ln. 


Antenne reddish, rather long, a good deal thickened 
towards the extremity ; 3rd joint about as long as, but 
more slender than 2nd; 4—6 subequal, rather small, 
bead-like; 7 and 8 broader than the preceding, rather 
transverse; 9 and 10 broader than the preceding, also 
transverse. Head broad and short, but distinctly nar- 
rower than the thorax, very dull, more obscure in colour 
than the other parts; the eyes large, but with a distinct 
prominent space at the sides behind them, the antennal 
tubercles short and strongly elevated, but without any 
distinct impression on the inner side of each. Thorax 
very broad and short, twice as broad as long, a good deal 
narrower than the elytra; the sides distinctly narrowed 
towards the base, and each with three or four minute 
setigerous prominences, giving them the appearance of 
being denticulated ; the surface reddish, very opaque, very 
densely and indistinctly punctured, with two indistinct 
longitudinal impressions on the middle, and outside these 
scarcely visibly impressed. Elytra broad, much longer 
than the thorax, rather distinctly and somewhat closely 
punctured, a little shining. Hind body large, very indis- 
tinctly punctured, the basal segment nearly dull, the 
others more shinmg, so that the 6th is quite shining. 
Legs clear yellow ; under surface unicolorous red, with the 
hind body densely and finely punctured and pubescent. 

Ega and Tapajos ; two individuals. 


4, Trogophleus hilaris, n. sp. Rufus, capite fusco- 
rufo ; antennis elongatis, articulis nullis transversis ; pro- 
thorace transverso, lateribus subdenticulatis, dorso minus 
distincte bi-impresso, angulis anterioribus minus rotun- 
datis; elytris dense minus fortiter punctatis; abdomine 
apicem versus nitidulo, Long. corp. 13 lin. 


Antenne elongate, formed almost as in YT. latifrons, 
but with joints 4—10 each slightly longer, so that 4—6 
are less bead-like, and 7—10 not transverse. Head very 
short and broad, with a very minute fovea on the vertex in 
the middle. Thorax twice as broad as long, the sides 
slightly rounded towards the front, and distinctly narrowed 


400 Mir. D. Shit?’ Contributions to the 


towards the base, and with two or three fine denticles ; the 
dise with two indistinct longitudinal impressions. Elytra 
much longer than the thorax, densely and indistinctly, but 
not altogether finely punctured. 

Tapajos and Ega; several specimens. 

Obs.—This species, though very closely allied to 7’. 
latifrons, is larger, and may be readily distinguished by its 
more elongate antennze. My description i is drawn entirely 
from one of the Tapajos specimens, for I am not at all 
sure that I have not before me two or three very closely 
allied species 3 ; two of the individuals are considerably 
darker in colour, so that the term ‘‘ piceo-rufo” would more 
correctly describe them, and one of these dark individuals 
shows, near the front angles of the thorax, a patch of 
peculiar elongate pubescence ; which may, however, only 
be wanting from the other individuals on account of their 


being rubbed. 


5. Trogophleus vicinus, n. sp. Rufus, capite fusco- 
rufo ; antennis elongatis, articulis nullis transversis ; pro- 
thorace transverso, lateribus subdenticulatis, versus angulos 
anteriores bene rotundatis, dorso minus distincte bi-im- 
presso; elytris dense minus fortiter punctatis; abdomine 
apicem versus nitidulo. Long. corp. 13 lin. 


This species is extremely closely allied tothe 7. hilaris, 
but it has the thorax a good deal more rounded towards 
the front angles, and the part of the head behind the eyes 
is less distinct and less prominent. In other respects I see 
scarcely anything to distinguish the two species. 

Amazons ; a single specimen, without special locality. 


APOCELLUS. 


This genus I consider one of the most interesting of the 
Staphylinide of the New World. It at present contains 
six species, found both in North America and South 
America. The facies of the species is greatly that of the 
Falagria forms of the Aleocharini, and the structure of 
the thorax is scarcely dissimilar from what may be found 
in some of the Aleocharini; the genus, therefore, affords 
us a connecting link between the Oxytelini and Aleocha- 
rint. The A. planus I here describe is of special interest 
as indicating in a certain manner what are the changes 
that have taken place in the head of the Aleocharini, so 
as to give rise to the appearance of a different insertion of 


Staphylinide of the Amazon Valley. 401 


the antenne. These changes may be briefly summed up 
as follows: in Osorius the labrum appears to be attached 
to the edge of the front of the head, but is, in fact, 
attached to a membrane underneath the front of the head, 
and is, therefore, mobile; in Apocellus this membrane 
intervenes in a very visible manner between the front of 
the head and labrum; for I consider the large semi- 
corneous portion of the head, intervening between the 
transverse suture (very visible in Apocellus) and the 
labrum, to be clearly the homologue of the membrane 
above mentioned in Osorius, and which is very visible in 
many of the Staphylinini. In the Aleocharini the trans- 
verse suture above alluded to has disappeared, and the 
antennal tubercles can scarcely be recognized. 


1. Apocellus planus, n. sp. Testaceus, metasterno, ab- 
domine, elytrisque plus minusve infuscatis ; capite, thorace, 
elytrisque opacis, dense subtilissime strigosulis; abdomine 
nitidulo, fere impunctato. Long. corp. 14 lin. 


Antenne yellow, rather stout and very elongate, longer 
than head, thorax and elytra; 2nd and 3rd joints slender 
and elongate, the latter a good deal the longer; 10th joint 
much longer than broad, 11th distinctly longer than 10th. 
Head yellow, the part in front of the transverse suture 
between the antennal tubercles more shining and less cor- 
neous than the other parts; the antennal tubercles strongly 
elevated, the front rendered opaque by very fine, indistinct, 
strigose sculpture, the middle with an indistinct fovea. 
Thorax small, only about half as broad as the elytra, about 
as long as broad, distinctly narrowed towards the base, 
very finely margined at the sides and base, subquadrate, 
but with the angles rounded; the surface rendered opaque 
by a very fine, indistinct, strigose sculpture. Elytra 
distinctly longer than the thorax, yellowish, but somewhat 
infuscate, especially towards the pleuree ; opaque, densely 
and finely strigose. Hind body broad, a little curved at 
the sides, shining yellowish, slightly infuscate, especially 
towards the extremity, almost impunctate ; its under face as 
well as the metasternum more distinctly infuscate. Legs 
elongate, pale yellow. 

Ega; three individuals, of doubtful sex.

Antenne yellow, quite as long as head and thorax, a 
good deal thickened towards the extremity ; 3rd joint dis- 
tinctly longer than 2nd, and a good deal ‘longer than 4th, 
which is slender and longer than broad; of 6—10 each is 
slightly longer and distinctly broader than its predecessor, 

each a little longer than broad; 11th long, a good deal 
longer than 10th. Head chestnut yellow, the hind angles 
very rounded, the clypeus large. Thorax narrow, scarcely 
so broad as the head, and Grpt much more ten half as 
broad as the elytra; it is longer than broad, quite convex, 
and with an impression at the base in the middle. Elytra 
quadrate, about as long as the thorax, of a chestnut colour, 
rather darker than the head and thorax. Hind body 
broad, but much narrowed at the base, so that its sides are 
greatly rounded ; it is of a yellowish colour, with the apical 
segments a little infuscate. The legs are long and slender, 
the four hind femora very slightly infuscate towards the 
extremity. 

Manaos; three individuals, captured by Dr. Trail in 
August, 1874. They were attracted by light. 

Obs.—An undescribed species from Rio de Janeiro is 
very closely allied to A. /evis, but is rather smaller, has 
joints 4—6 of the antenn longer, and the hind body more 
contracted at the base. 


OMALIUM. 


The insignificant little species I here describe with this 
generic name is interesting, as being the only representa- 
tive of the Omalini yet detected in the Amazons. Indeed, 
the group seems to be extremely poorly represented in 
tropical America, only two species of it having as yet 
been described from those parts, and scarcely any others 
existing, so far as I know, in collections ; it is, however, 
quite possible that this paucity may prove not to be so 
complete as these facts would suggest, for our knowledge 
of the smaller species of tropical Staphylinide is still so 
very fragmentary, that no generalization as to an exten- 
sive group can with propriety be more than hinted at.

race transverso, dorso obsolete bi-impresso. Long. corp. 
& lin. 

Antenne short, the five basal joints yellow, the others 
black ; 2nd joint short and stout, 3rd very slender, 4th and 
5th similar to one another, very small; 6—10 strongly trans- 
verse, the 6th much broader than the preceding ones, 7th 
broader than 6th, and 8th than the 7th; 8—10 very similar 
to one another, 11th short. Palpi yellow. Head greatly 
narrower than the thorax, only half as broad as the elytra ; 
black, indistinctly but not altogether finely punctured, 
almost dull ; ocelli small but distinct. Thorax about twice 
as broad as long, distinctly narrower than the elytra; the 
sides rounded and rather more narrowed in front than 
behind; on the middle are two very obsolete, large im- 
pressions ; its punctuation is obsolete, but it is scarcely 
shining. Elytra twice as long as the thorax, their outer 
hind angle rounded, the sutural one almost rectangular ; 
they are rather closely but quite indistinctly punctured, 
the punctuation at the apex becoming even finer and more 
indistinct than at the base; they are black and almost 
opaque. Hind body black, dull, its punctuation exces- 
sively fine, the lateral margins broad. The legs are yellow, 
but somewhat infuscate ; they are short and slender; the 
tarsi are very short; the metasternum has a deep channel 
on its hinder part. 

Two individuals of this species were found by Dr. Trail 
on the 5th November, 1874, but he has sent me no special 
locality. 


PIESTUS. 


The insects of this genus are confined to the warm 
parts of the New World, though it must not be forgotten 
that the North American and European genus Siagonium 
approaches them very closely. The genus comprises 
about eighteen described species, and I here add five 
to that number. Of these five, two—viz., P. validus and 
P. frontalis—belong to the group of large species having 
the head armed with horns, and the mandibles much 
developed; P. rectus belongs to the P. minutus, Er., 
eroup; while P. rugosus and P. aper have as their only 
described near ally, P. angularis, Fauv. 

The species of the genus have, many of them, an ap- 
parently wide range in South America, and their dis- 
crimination from one another in a satisfactory manner

404 Mr. D. Sharp’s Contributions to the 


is a matter of great difficulty. The characters by which 
the sexes may be distinguished are extremely slight; in 
some species the antennz are very elongate in some male 
specimens, but in other individuals scarcely differ at all 
from those of the female, while the structure of the edeagus 
shows scarcely any variation in very dissimilar species. 


1. Piestus validus, n. sp. Niger, nitidus, subdepressus, 
abdominis apice piceo; antennis setosis, articulis 1, 3, 4 
et 5 setis intus densioribus; fronte bispinosd, spinis 
approximatis ; prothorace sat crebre obsolete punctato. 
Long. corp. 6 lin. 


Antenne blackish, rather stout, 24 lin. in length, 
clothed with tawny, elongate sete. These sete are specially 
long and dense on the inner side of the Ist, 3rd and 4th 
joints, while the 5th joint is less setose than the 4th, but 
more than the 6th. Front of head armed with two mode- 
rately long acuminate spines; behind these the head in the 
middle is depressed, the depression shaped somewhat like 
a narrow V; the spines at nearly half their distance from 
the base are only separated by a width of about 4% of 
a line; the surface is sparingly and finely punctured. 
Thorax 1 lin. in length, 13 lin. in breadth, channelled 
along the middle, transversely a little convex; the surface 
very shining, and with rather numerous, but obsolete 
punctures. Elytra shining black, 1} lin. in length, their 
ereatest breadth just that of the thorax, viz., 14 lin., each 
with 5 deep striz, and outside these with indications of a 
6th stria sufficiently well marked at the extremity. Hind 
body black, not very shining; the seements punctured at 
the base and sides of each, the basal segment nearly 
entirely coriaceous; the extremity pitchy yellow, the 
paler colour commencing on the hind part of the 6th 
seoment. Legs black, with the tarsi pitchy. 

Pebas ; three specimens, 2 ¢,1 &. 

Obs. I.—There are several species of Piestus mixed in 
descriptions and collections under the name of P. bicornis. 
I have not, however, seen the above-described species from 
any other locality than this of the Upper Amazons; its 
large size, together with its distinctly punctured thorax, 
distinguish it from all the closely allied forms. 

Obs. IT—I have ascertained the sexes of this species 
by dissection, without which they cannot be distinguished. 
Of the two males, one has the thorax remarkably developed, 


Staphylinide of the Amazon Valley. 405 


it being considerably broader than the elytra and more 
arched transversely. As this is probably an extreme 
sexual characteristic, my description has been made from 
the smaller male, which, in the development of its thorax, 
quite resembles the female. 


2. Piestus bicornis, Ol., Er. 


Para; two female specimens. Var. Oxytelinus, Lap.; 
seven specimens from Ega. I am very doubtful whether 
this so-called variety be not rather a distinct species. 


3. Piestus spinosus, Fab., Er. 
Para and Ega; six individuals. 


4. Piestus frontalis, n. sp. Depressus, rufescens, 
nitidus, antennis elongatis; capite vertice bi-impresso, 
fronte spinis duabus brevibus distantibus armata; pro- 
thorace medio canaliculato, et punctato; elytris punctato- 
striatis. Long. corp. 43 lin. 

Antenne elongate and rather slender, 33 lin. in length; 
the three basal joints red, the others pitchy. Mandibles 
moderately long, greatly curved, each with a very long 
transverse tooth on the inner side; in the middle and on 
the upper side with a tooth some distance from the 
extremity; on the right mandible this tooth elongate and 
spine-like. Head shining dark red, without punctures; 
the front armed on each side with a short straight horn, 
the distance between the two horns being about 3 lin.; 
within the antennal elevations the surface is depressed on 
each side, the two depressions are not connected by a 
channel. Thorax strongly transverse, ? lin. in length by 
13 in width; very shining red, with a channel along the 
middle, and the disc with a few distinct punctures. Elytra 
14 lin. in length by fully 1} in width, each with five deep 
punctured striz, and with traces of a 6th stria externally. 
Hind body broad, infuscate-red, with the extremity paler, 
coarsely but not closely punctured. Legs red. Hind 
margin of prosternum in the middle almost straight; 
mesothoracic keel very obsolete. 

Ega; a single individual, of doubtful sex. 

Obs. I— Though closely allied to P. spinosus, this species 
is rather smaller, and is very readily distinguished by the 
differences of the mandibles, of the frontal horns, and of 
the vertex. 


ow 
406 Mr. D. Sharp’s Contributions to the 


Obs. II,—It is only after a good deal of hesitation that 
I have decided to consider this insect a new species. 
P. capricornis, Lap., Ev., must be closely allied to it if not 
the same species. Laporte’s figure represents an insect 
with less transverse thorax, and his words, ‘‘abdomen 
finement ponctué,” are singularly inapplicable to the 
species I have described above as P. frontalis. Erichson’s 
description of P. capricornis agrees much better with the 
P. frontalis. Nevertheless, though Erichson gives a 
detailed description of the mandibles of his species, he 
omits any notice of the remarkable transverse spine-like 
tooth which exists on the inner side of each mandible in 
P. frontalis, this being one of the most striking character- 
istics of the species. 


5. Piestus rectus, n. sp.  Rufescens, antennis (basi 
exceptis), capite abdomineque piceo-rufis ; capite vertice 
unifoveolato, antice utrinque curvatim lineato; abdomine 
segmento 6° toto dense punctato. Long. corp. 3 lin. 


Antenne 1 lin. in length, the basal joint red, the two 
following pitchy red, the rest pitchy; the Ist joint not 
swollen on the upper side, but with a rough spot bearing 
a few long hairs, the other joints with sparing sete. Head 
on the upper side blackish, shining, the middle part nearly 
on a level with the antennal elevation, on the inner side 
of this latter is a curved impression ; ‘these impressions 
are much abbreviated behind, so that they are far from 
meeting; the vertex is quite flat and bears a distinct fovea 
in the middle; the surface is sparingly sprinkled with fine 
punctures. Thorax strongly transverse, reddish, very 
shining, channelled along the middle; the surface with 
excessively obsolete, sparing, fine punctures, only to be 
detected on a careful examination with a high power; the 
hind angles obtuse, the impression near the hind angle 
small. Elytra just as broad as the thorax, about % lin. in 
length and # lin. in breadth, shining red, with the suture 
and outer and hind margins indistinctly blackish, each 
with five moderately fine strize, which are indistinctly 
punctured. Hind body broad and parallel, pitchy, rather 
coarsely and closely punctured; segments 2—4 each with 
a smooth space in the middle behind, the punctures on 
the corresponding part of the 5th segment more sparing 
than at the base, the 6th evenly and ‘distinctly punctured 
throughout; its extreme hind margin reddish, as are the 


Staphylinide of the Amazon Valley. 407 


following segments; on the underside the hind body is 
pitchy red, paler towards the extremity, and all the 
segments 2—6 are coarsely and rather closely punctured ; 
on segments 3 and 4 and base of 5 the punctures are 
almost wanting on a small space on the middle. Legs red. 

Ega; four individuals, probably all females. 

Obs. I.—Besides the specimens above described, I have 
another individual from the same locality (Ega), which 
T believe to be the male of P. rectus; it is rather smaller 
than the individuals described, but the antennz are 23 lin. 
in length, the head is longitudinally depressed along the 
middle, and the front part is scarcely shining, being 
minutely strigose; the Ist jomt of the antenne is more 
densely penicillate, and the 2nd and 3rd joints have also 
a dense long pubescence on the inner face. 

Obs. IL.—-I believe the most closely allied described 
species to be P. pennicornis and P. plagiatus, Fauv. I 
have a fourth still undescribed species in my collection 
from Rio, which is considerably larger, but has the head 
similarly formed and, as well as the antenne, manifesting 
similar sexual disparities. 


6. Piestus minutus, Er., Fauv. 

Paré and Ega; four individuals. These individuals 
indicate a peculiar race, which I have not seen from any 
other locality ; they are small (about two lines in length), 
and broad in proportion to their width; the elytra are 
nearly black in mature individuals. 


7. Piestus pygmeus, Lap., Er. 

Paré and St. Paulo; numerous specimens. This is 
another very puzzling species, owing to the variations it 
exhibits, and it is quite possible that two or three closely - 
allied species are mixed under this name. 


8. Piestus sulcatus, Grav. 


Para, Lages, Anan4; five specimens, which agree exactly 
inter se and only differ slightly from individuals from Bahia. 


9. Piestus rugosus,n.sp. Piceus, pedibus abdominisque 
apice rufescentibus, opacus ; prothorace dense rugoso, 
lateribus pone medium obtuse dentatis; elytris leis 
6 elevatis ; abdomine dense punctato. Long. corp. 23 lin.

Antennz 14 lin. in length, rather stout, pitchy black, 
with the basal joints rather paler; of joints 4—10 each is 
a little longer than its predecessor. Head with two curved 
lines on the front part, which meet so as to form an acute 
angle on the middle of the head; antennal callosities stout, 
but not greatly elevated; the whole surface densely rugose, 
quite opaque. Thorax strongly transverse; the sides 
rounded and distinctly narrowed in front, behind the 
middle with a short stout tooth, and behind this tooth cut 
away, the hind angles being distinctly marked and just 
rectangular; the whole surface is densely and coarsely 
rugose, quite dull; there is no distinct impression along 
the middle, and in front of the hind angles is a scarcely 
definite longitudinal impression, reaching nearly to the 
front margin. Elytra longer than the thorax, their 
sculpture on each consisting of a sutural, and six other 
fine, elevated, longitudinal lines; the broad spaces between 
these lines are peculiarly opaque, and are marked with 
some indistinct transverse marks, which probably represent 
obsolete coarse punctures. Hind body quite dull, densely 
and rather finely punctured ; the apical segments and the 
hind margin of the 6th segment reddish; under surface 
not so dull as the upper; metasternum covered with 
coarse punctures and with a fovea at the extremity in the 
middle. Legs dull red. 

Ega; a single individual, whose sex is unknown. 


10. Piestus aper,n. sp. Opacus, piceus, pedibus rufis ; 
capite mutico, longitudinaliter striguloso; prothorace 
lateribus trisinuatis, dense fortiterque punctato; elytris 
lineis 6 elevatis: interstitiis transversim rugosis; abdomine 
gene fortiterque punctato, apice dilutiore. Long. corp. 
12 lin. 


Antenne 11 lin. in length, stout, pitchy, the basal joints 
obscure red; 3rd joint scarcely so long as 2nd, 4th a good 
deal stouter than and quite as long as 3rd, 5—10 differing 
little from one another in length, each slightly stouter 
than its predecessor, 11th a little longer than but scarcely 
so broad as 10th. Head without impressions or lines, the 
antennal callosities only being present ; the surface densely 
covered with longitudinal rugz. Thorax broader than 
long, the front margin a little sinuate on each side the 
middle, so that the front angles are somewhat prominent ; 
the sides each with two notches, so that they exhibit three 


Staphylinide of the Amazon Valley. 409 


obtuse projections, and behind these much cut away at 
the hind angles; the surface covered with coarse dense 
punctures, so that the interstices are very narrow. 
Elytra rather broader and a good deal longer than the 
thorax, each with seven fine, raised, longitudinal lines, of 
which one is close to the suture and indistinct, and the 
outer one most distinct; the spaces between these lines 
marked with transverse lines, which are irregular, and 
represent a coarse confluent punctuation. Hind body 
coarsely punctured, the punctuation becoming more in- 
distinct on the apical segments, which also are paler in 
colour. Metasternum coarsely, closely and deeply punc- 
tured throughout. Legs reddish; tarsi short, pubescent 
beneath, the basal joint of each distinctly broader than the 
others. 
St. Paulo; two individuals, of uncertain sex. 


HYPore.us. 


Only four species have yet been described as forming 
part of this genus; one from Kansas, and the others from 
tropical America; to these I now add a fifth species. It 
is probable that the genus, like Piestus, is one of the 
forms characteristic of the South American fauna. 

I feel considerable doubts whether the species should at 
present be separated from Piestus. The two genera are 
extremely close in their general structure, and the only 
characters given to distinguish them are drawn from the 
trophi; but as the oral organs are subject to an excessive 
difference of development within the bounds of the genus 
Piestus, and as the comparison of these parts rests, so far 
as I know, on the examination of a single species of each 
genus, it is clear enough that the individuality of the 
genera has not yet been properly determined. 


1. Hypotelus micans, n. sp. Piceo-rufus, nitidus, an- 
tennis pedibusque rufo-testaceis; elytris stramineis, sutura 
epipleurisque infuscatis; capite thoraceque sat crebre, 
distincte, elytris parcius obsoletiusque punctatis. Long. 
corp. 1 lin. 


Antenne reddish, not thickened at the extremity; 3rd 
joint much shorter than 2nd ; 4th joint small ; 5th to 10th 
broader than the preceding joints, differing little from one 
another, each subquadrate. Head rather small, dark 
reddish, shining, rather sparingly but quite distinctly

punctured, and with two large, well-defined impressions. 
Thorax a good deal broader than long, rounded at the 
sides, and a good deal narrowed behind, similar in colour 
to the head; the surface shining, rather sparingly but 
quite distinctly punctured, with an excessively fine abbre- 
viated impressed line on the middle. LElytra a good deal 
longer than the thorax, sparingly and indistinctly punc- 
tured, pale shining-yellow ; the suture infuscate, and the 
pleurz piceous. Hind body pitchy, with the extremity 
reddish; the segments scarcely punctured, but finely 
strigose at the sides and base. Legs reddish-yellow. 
ga; a single individual. 


ISOMALUS. 


This genus at present consists of about twenty-five 
described species found in all the warm parts of the 
world; the genus Chasolium, Cast., is apparently not 
sufficiently distinct from Jsomalus to be at present adopted 
with advantage. The species are of the most difficult 
character, in so far as their discrimination from one 
another is concerned. I am not able to point out any 
external characters to distinguish the sexes; in certain 
species some males have the head very large, but it seems 
that this extra development in other individuals of the 
same sex and species disappears entirely. 


1. Isomalus agilis, n. sp. Latiusculus, parallelus, 
perdepressus, nitidus, fere levis, rufo-castaneus; capite 
oblongo; thorace lateribus antice rectis, postice rotundatis, 
margine anteriore utrinque impresso; elytris thorace paulo 
longioribus. Long. corp. 24 lin. 


Antenne slender, shorter than head and thorax, red, 
scarcely thickened towards the extremity; 10th joint 
almost as long as broad; 11th elongate, fully twice as 
long as 10th. Palpi red. Head as broad as thorax, 
oblong, the sides quite parallel, shining red, almost im- 
punctate. Thorax quite as long as broad; the sides in 
front nearly straight, behind the middle rounded and 
narrowed towards the base; the front margin on each 
side bears a rather large impression, and at the hind 
angle on each side are two indistinct depressions, one in 
front of and external to the other. lytra a little longer 
than the thorax, red, very shining, a little infuscate at the 


Staphylinide of the Amazon Valley. 411 


extremity and sides, each with a fine puncture on the 
middle. Hind body reddish, shining, impunctate. 

Ega; three individuals, one of which bears a label, 
“under bark, nimble.” 


2. Isomalus dubius,n.sp. Perdepressus, piceus, nitidus, 
fere leevis, antennis pedibusque testaceis; thorace basin 
versus fortiter angustato; elytris disco unipunctatis. Long. 
corp. 13—1 lin. 

Antenne rather longer than head and thorax, slender, 
reddish, slightly thickened towards the extremity; 3rd 
joint a little longer than 2nd; 10th joint quite as long as 
broad, 11th a good deal longer than 10th. Head as 
broad as the thorax, flat, impunctate, very shining, pitchy, 
with the mandibles and parts of the mouth red. Thorax 
as broad as the elytra; the sides rounded at the front 
angles, greatly narrowed behind, with an indistinct denticle 
behind the middle, the base very narrow ; shining piceous, 
almost without sculpture, the front margin on either side 
bearing two approximate punctures. LElytra narrowed 
towards the shoulders, a good deal longer than the thorax, 
shining, pitchy, each with a puncture on the middle. 
Hind body broad, flat, piceous, paler at the extremity, 
impunctate, bearing a few upright sete. Legs reddish. 

ga; three individuals, which vary in size, in the 
development of the head, and in the length of the 
antenne. 

Obs.—This species is extremely closely allied to 7. pal- 
lidipennis, Fauv., but is a little larger, has the elytra 
concolorous, and the antenne a little longer, 


3. Isomalus tenuis, Fauv. 


St. Paulo; a single individual. The species was de- 
scribed by Fauvel from a specimen coming from Venezuela; 
the St. Paulo exponent does not differ from an example in 
my collection from Santa Rita, Brazil, so that the species 
appears to possess a wide range. 


LISPINUS. 


This genus as at present constituted consists of about 
forty described species, which occur pretty generally in 
the warmer parts of the globe; though not yet recorded 
from Australia, I can state that species of the genus occur 
even there. The distinction of the species from one 


_ 
412 Mr. D. Sharp’s Contributions to the 


another appears to me likely to be a point of great diffi- 
culty, owing to the extreme general resemblance that 
exists between numerous species. The genus Holosus of 
Motschoulsky and Kraatz appears to be excessively closely 
allied to Lispinus, and scarcely justifies the adoption for 
it of a distinct generic name in the present state of our 
knowledge of the exotic Staphylinide. The South 
American species of Lispinus appear to me to belong to 
two groups, easily distinguished from one another by “the 
form of the head; in Z. ‘striola and its allies the antennal 
tubercles are quite obsulete, and the front of the head is 
very evenly and distinctly margined, and its upper surface 
convex, while in the other group the antennal tubercles 
are distinct, and the front of the head is scarcely or not at 
all margined. L. simplex and L. letus, here described, 
belong to this latter group, while all the other species 
I here describe belong to the first-mentioned group, the 
L. depressus making, however, a considerable approach 
to the second group. 


1. Lispinus striola, Er. 

Para; a series of specimens. 

This is, apparently, one of the species of Staphylinide 
having a great geographical range in the warm parts of the 


New World. 


2. Lispinus catena, n. sp. Elongatus, angustulus, 
parallelus, nigro-piceus, nitidus; antennis, pedibus, abdomi- 
nisque apice rufis ; thorace basin versus leniter angustato, 
lateribus haud sinuatis, basi utrinque impressione angusta ; 
capite thoraceque sat crebre et subtiliter punctatis; elytris 
parcius punctatis, disco striolé minus discreté e punctis 
elongatis formata notatis. Long. corp. fere 24 lin. 


Antenne reddish ; joints 7—10 transverse, 3rd slightly 
longer than 2nd. Head rather finely and moderately 
closely punctured, on the disc with two larger distant 
punctures. Thorax not quite so long as broad; the sides 
only a little narrowed towards the base, on each side near 
the hind angles with a narrow, elongate impression, reach- 
ing quite half-way to the front; on the middle is an ex- 
cessively fine channel; the surface is rather finely and 
moderately closely punctured. Elytra a little longer than 
the thorax, only a little less shining, sparingly but not 
altogether finely punctured, the punctures being rather 


Staphylinide of the Amazon Valley. 413 


elongate; along the middle these punctures are crowded 
together and confluent, so as almost to form an impressed 
stria; the sutural stria deep. Hind body narrow and 
elongate, cylindric, blackish, with the extremity reddish ; 
above finely and indistinctly punctured, beneath the oblique 
striz on the sides of each segment are quite distinct. Legs, 
including the coxe, red. 

Ega; a single specimen, which I believe to be a female, 
and an individual of a slightly different variety from Para. 

Obs.—This species may readily be distinguished from 
L. striola by the more setose surface, by the more slender 
joints of the base of the antennz (2—5), and by the less 
ample elytra and hind body; its nearest described ally is 
probably ZL. quadripunctulus, Fauvel. 


3. Lispinus apicalis, n. sp. Niger, nitidus, antennis 
piceis, pedibus abdominisque apice summo rufis; thorace 
elytrisque crebre sat fortiter punctatis ; abdomine punctis 
magnis leviter impressis, puncto singulo parte posteriore 
omnino deficiente, segmento apicali fortiter profundeque 
punctato. Long. corp. 2? lin. 


Antenne rather stout; 3rd joint nearly twice as long as 
2nd, 7—10 each a little transverse. Head a good deal 
narrower than the thorax, distinctly, moderately closely 
punctured. Thorax a good deal broader than long, the 
sides nearly straight, only slightly curved; it is covered 
with rather coarse, moderately close punctures, bears an 
extremely fine channel on the disc, and an elongate im- 
pression near the outer angles, which extends considerably 
more than half-way to the front. Elytra a good deal 
longer than the thorax, rather coarsely punctured; the 
punctures at the outside, however, quite fine, and at the 
lateral margins wanting. Hind body a little flattened, 
blackish, with the hinder part of the 7th segment red; 
the segments on the upper side bear a peculiar obsolete 
punctuation, the hinder part of an obsolete coarse puncture 
being entirely wanting ; the 7th segment, however, offers 
a striking contrast to the preceding ones, for it is deeply 
and distinctly punctured: the under surface of the hind 
body bears numerous fine, raised, oblique striee. 

Para ; a single individual (I believe a female), collected 
by Mr. Smith.

abdomine punctis magnis leviter impressis, puncto singulo 
margine posteriore omnino deficiente, segmento apicali 
fortiter punctato. Long. corp. 23 lin. 


Antenne dark red, moderately stout; 3rd joint much 
longer than 2nd, 7—10 slightly transverse. Head rather 
finely punctured. Thorax broader than long, straight at 
the sides and not narrowed behind; rather closely punc- 
tured, with a narrow smooth space along the middle, and 
an elongate impression near each outer angle, which 
reaches more than half-way to the front. Hind body 
punctured as in L. apicalis, but the punctures on the 7th 
segment not quite so deep and coarse. 

Pard; a single individual (I believe a female), collected 
by Mr. Smith. 

Obs.—This species is extremely closely allied to L. apz- 
ealis, but is not quite so large, and the sculpture of the dorsal 
plate of the 7th segment is a good deal less coarse. It is 
very similar in size and form to L. striola, but has the 
3rd joint of the antennz longer. ‘The elytra are without 
the discoidal stria of Z. striola, and their sutural portion 
is more coarsely punctured, and the sculpture of the hind 
body is different. 


5. Lispinus punctatus, n. sp. Nigro-piceus, nitidus, 
fortiter punctatus, antennis piceis, pedibus abdominisque 
apice rufis; capite lato; prothorace transverso, basin 
versus angustato, basi utrinque impresso. Long. corp. 
2 lin. 


Antenne stout and short; joints 4—6 broader than 
long, 7—10 distinctly broader than the preceding, strongly 
transverse; 11th joimt short, rather paler than the 10th. 
Head broad and short, with a small impression on each 
side, near the front; rather coarsely punctured, the punc- 
tures towards the vertex finer and more sparing, over the 
eyes almost passing into striw. Thorax much broader 
than long, a good deal narrowed towards the base, and 
a little sinuate in front of the hind angles; shining black, 
coarsely and rather closely punctured, with an excessively 
fine channel on the middle, close to each hind angle, with 
a broad but not sharply limited impression, the front part 
of which forms a narrow, indistinct channel. Elytra 
a good deal longer than the thorax, coarsely, deeply, and 


Staphylinide of the Amazon Valicy. 415 


rather closely punctured with elongate punctures. Hind 
body shining black, red at the extremity; on the upper 
surface distinctly punctured along the middle and at the 
sides with oblique striz, the basal segment broadly opaque 
at the base; its under surface shining and with shallow, 
oblique striz. Legs red. 

Ega; a single male. 


6. Lispinus cognatus, n. sp. Nigro-piceus, nitidus, 
fortiter punctatus, antennis piceis, pedibus abdominisque 
apice summo rufis; prothorace transverso, basin versus 
angustato, basi utrinque impresso. Long. corp. 1# lin. 


Antennz short, rather stout; joints 4—6 a good deal 
broader than long, 7—10 strongly transverse. Head 
rather large, with a very small impression on each side 
near the front; the surface shining, moderately closely’ 
and finely punctured. Thorax rather strongly transverse, 
distinctly narrowed towards the base, the surface rather 
coarsely and closely punctured, and at each hind angle 
with an ill-defined, not very large impression. Elytra 
a good deal longer than the thorax, coarsely and closely 
punctured. Hind body cylindric, but a little depressed ; 
on the upper surface along the middle segments 2—5 are 
rather coarsely but indistinctly and not closely punctured, 
at the sides the punctures become obscure oblique striz ; 
the 6th segment finely and sparingly punctured; the 
front portion of the basal segment with a moderately 
broad opaque space at the base. Legs red. 

Ega; a single individual, which I believe to be a male. 

Obs.—This species is very closely allied to L. pune- 
tatus, but is a little smaller, and the head and thorax are 
narrower in proportion to their length, and the impressions 
on the thorax are narrower in their basal portion, and the 
antenne are not so stout. 


7. Lispinus modestus,n.sp. Angustulus, subparallelus, 
piceus, pedibus abdominisque apice rufis; minus nitidus, 
crebre sat fortiter punctatus, abdomine segmento 6° sat 
crebre punctato, Long. corp. 2 lin. 


Antenne short, not much thickened towards the extre- 
mity; jomts 4—6 rather stout, the 6th distinctly trans- 
verse; 7—10 broader than the preceding, rather strongly 
transverse. Head distinctly narrower than the thorax, 
rather closely and finely punctured, and with a distinct 


416 Mr. D. Sharp’s Contributions to the 


small impression on each side towards the front. Thorax 
a little broader than long, the sides a little narrowed 
towards the base, not at all sinuate; the surface moderately 
finely and closely punctured, near each hind angle, with 
an elongate impression. Elytra distinctly longer than the 
thorax, their punctuation rather coarser than, and not 
quite so close as, that of the thorax. Hind body de- 
pressed, cylindric, but little shining; all the segments, in- 
cluding the 6th, distinctly punctured along the middle, the 
punctures at the sides becoming shallow striz; on the 
under face the striz along the sides are more deep and 
distinct, the punctures along the middle sparing. Legs 
red. 

Ega; a single individual, which I believe to be a 
female; also two specimens from Para, collected by Mr. 
Smith. 


8. Lispinus planus, n. sp.  Rufo-piceus, depressus, 
parallelus, fere opacus, antennis pedibusque rufis ; capite 
thoraceque subtiliter sat crebre punctatis; elytris parcius 
punctatis; thorace basi utrinque profunde longitudinaliter 
impresso ; lateribus basin versus subsinuatis. Long. corp. 
fere 1? lin, 


Antenne reddish, rather slender at the base, distinctly 
thickened towards the extremity; joints 4—6 not at all 
transverse, 7—10 distinctly broader than the preceding, 
each a little transverse. Head narrower than the thorax, 
rather short; the surface finely and not closely punctured, 
and with a small punctiform impression on each side the 
middle towards the front. Thorax broader than long; the 
sides scarcely narrowed till near the base, where they are 
a little contracted; the surface finely and not closely punc- 
tured, close to each hind angle with a large longitudinal 
impression, which is sharply limited both on the inside and 
the outside; it extends more than half-way to the front, 
and is opaque at the bottom, because of a very dense, fine 
sculpture. Elytra a good deal longer than the thorax, 
rather sparingly punctured with elongate but not deeply 
impressed punctures. Hind body flattened, pitchy red, 
red at the extremity, sparingly and indistinctly punctured. 
Legs red. Metasternum with an ill-defined longitudinal 
impression along the middle. 

Ega; one male and one female individual. 

Obs.—This species is, no doubt, allied to L. linearis, 


Staphylinide of the Amazon Valley. 417 


Er.; it is probable that the Z. linearis of Fauvel (Not. 
Ent. 11. p. 47) is a distinct species from that of Erichson, 
and I have three or four other very closely allied species 
from different parts of Brazil. 


9. Lispinus depressus, n. sp. Rufescens, depressus, 
parallelus, fere opacus; capite thoraceque subtiliter sat 
crebre, elytris parcius punctatis; thorace basi utrinque 
profunde longitudinaliter impresso, lateribus basin versus 
subsinuatis. Long. corp. 13 lin. 


This species resembles extremely ZL. planus, but is 
rather smaller, narrower and paler in colour; the antennze 
are a trifle more slender, and the punctuation of the upper 
surface is just a little finer. I should have considered it 
a small pale variety of Z. planus, had it not been that the 
metasternum possesses only very indistinct traces of any 
impression along the middle. 

Ega; a single female individual. 


10. Lispinus simplex, n. sp. Piceus, depressus, sub- 
opacus, parce obsoletissime punctatus, antennis pedibusque - 
testaceis ; elytris disco impunctatis. Long. corp. § lin. 

Antenne yellowish, a good deal stouter at the extremity 
than at the base; 3rd joint shorter and more slender than 
2nd, 4—6 small; 7—10 broader than the preceding 
joints, short, and though not very broad decidedly trans- 
verse. Head rather small, margin of the clypeus very in- 
distinct, antennal tubercles distinct, eyes rather prominent ; 
the surface nearly dull from being finely coriaceous, and 
also showing a few excessively fine punctures. Thorax 
transverse, a little rounded at the sides and with the basal 
portion distinctly contracted; the surface with a sculpture 
similar to that of the head, with an excessively fine 
channel along the middle, and with a broad, short, very 
ill-defined impression at each hind angle. Elytra much 
longer than the thorax, finely coriaceous and dull, each 
with a distinct puncture on the disc, and with a few 
very obsolete punctures. Hind body almost impunctate, 
dull, the extremity and the hind margin of each segment 
yellowish. Legs yellow. 

Ega; two individuals, of doubtful sex.

colour is infuscate-red, the surface is shining, but ver 
finely coriaceous, and with a few excessively, ‘fine bes

sides and narrowed behind, shining reddish, with a very 
few extremely obsolete punctures, and with an indistinct 
impression near each hind angle. Elytra much longer 
than the thorax, bright yellowish-red, almost impunctate. 
Hind body infuses ate-reddish, the extremity and the hind 
margin of each segment brighter, impunctate, the sides of 

each seement coriaceous. Legs bright yellow.

THoraxopHorus, Motsch. (Glyptoma, Er.) 


Under this generic name there are mixed in collections 
and entomological works two distinct genera ; of these, the 
one to which Glyptoma crassicorne, Er., and its allies 
belong, is allied to Lispinus ; while the other, containing 
Thoraxophorus corticinus, Motsch., and its allies, is one 
whose natural affinities are much more obscure to me. Of 
the two new species here described, one, 7. opacus, is 
allied to G. crassicorne, while the other, 7. crassus, is an 
ally of 7. corticinus. Of these two genera or groups, the 
one containing G. crassicorne is peculiar to South Ame- 
rica, while the other is found in South America, North 
America, Europe and East India. 


1. Thoraxophorus opacus, n. sp. Elongatus, niger, 
opacus, pedibus piceis; antennis crassiusculis, elongatis, 
articulo 2° solum transverso; elytris unicostatis; abdomen 
cylindricum. Long. corp. 1 lin. 

Antenne stout, about 1 lin. in length, blackish; 2nd 
joint smaller than the others, not so long as broad; 3rd a 
little longer than 4th, quadrate, 4th nearly as long as 
broad; 5—10 differing little from one another, each a 
little longer than broad ; 11th joint pointed at apex. Head 
quite as broad as thorax; the surface dull, velvet-like, 


Staphylinide of the Amazon Valley. 419 


coarsely but quite indistinctly punctured, the vertex with 
two indistinct elevations. Thorax narrower than the elytra, 
rather longer than broad; the sides straight from the front 
angles till. just behind the middle, thence suddenly nar- 
rowed to the base; the surface dull and velvet-like, with a 
broad impression “along the middle, most distinct on the 
front part; the lateral portions with coarse, indistinct punc- 
tures. Elytra longer than the thorax, each with a sharply- 
defined, longitudinal line down the middle; the surface 
dull and quite obsoletely punctured. Hind body cylindri- 
cal, elongate, dull and velvet-like, the basal segments with 
some coarse rugosities, the apical ones almost without 
sculpture. Legs pitchy. 

Eiga; a single individual, 

Oiso_ Kk species very closely allied to the above, and 
apparently as yet undescribed, is not uncommon in Brazil ; 
it has the antenne shorter, the penultimate joints being

parallel with the clypeus; along the middle two strongly 
raised, longitudinal marks, which are connected in front ; 
the hind angles projecting and quite acute, the surface 
depressed between the elevations. Thorax strongly trans-

St. Paulo; a single individual. 

Obs.—I have also in my collection an individual of this 
species, which was captured by Mr. Squires near Rio de 
Janeiro. 


LEPTOCHIRUS. 


I find that considerable confusion exists both as to the 
generic characters and the specific forms represented by 
the name Leptochirus. There are, it seems to me, two dis- 
tinct forms confounded under the generic name, viz., one 
in which the anterior cox are separated by a well-deve- 
loped process of the prosternum, and another in which this 
process is absent; L. scoriaceus, and all the Amazonian 
species here described, belong to the first of these groups, 
as do also L. laticeps and other species from the tropics of 
the Eastern hemisphere. On the other hand, a large 
number of the Eastern species, such as L. ebeninus and 
L. mandibularis, have the front coxe comparatively elon- 
gate and exserted, and the division between their cavities 
quite concealed, so that it is probable they will ultimately 
be considered generically distinct; it is to this latter group 
that the ZL. bicornis, Fauv., from Mexico, should be 
referred. 

The species of the genus as yet described from the New 
World are only seven in number, but they are in reality 
more numerous than has been supposed, for I have at 
least a dozen undescribed species from this part of the 
globe in my own collection. ‘The species, are, however, 
very difficult to distinguish, from their great similarity, 
and demand a careful study before their distinctions can 
be satisfactorily elucidated. I can only satisfy myself as 
to four distinct species from the Amazons, two of which 
I here describe as new. 


1. Leptochirus fontensis, n. sp. Nigerrimus, nitidus, 
fronte bi-impressa, clypeo oblique declivo, utrinque acute 
tuberculato, pone tuberculam bipunctato ; abdomine supra 
fere impunctato. Long. corp. (extenso) 8 lin. 


Antenne 2 lin. in length; 10th joint scarcely so long as 
broad. Head with the two frontal impressions without 
punctures, or rather each with two very indistinct punc- 
tures; clypeus descending obliquely from the front, with an 


4 


Staphylinide of the Amazon Valley. 421 


acute tubercle on each side, and behind this with two 
coarse punctures on each side. Thorax scarcely 1} lin. in 
length by 14 in breadth. Elytra just as long as thorax, 
with their inflexed margin rather coarsely punctured. 
Hind body slender; on the upper side, at the base of each 
seement, there are no punctures in the middle; on the 
under side the basal segment is without punctures in the 
middle; the following segments rather coarsely punctured 
at the base; the 6th segment more sparingly than the 
the others; metasternum with only ten or twelve not very 
distinct punctures on each side, external to the middle 
COR. 

Fonte Boa; two individuals, communicated by Dr. 
J. W. H. Trail, who captured them there on the 17th 
October, 1874; and also found at Ega by Mr. Bates. 

Obs. I.—This species, in the structure of its head and 
mandibles, is very closely allied to the Brazilian L. scoria- 
ceus, Germ, but is much smaller and especially narrower ; 
the antenne are considerably shorter, and the fine dense 
punctuation found at the base of each of the two or three 
front segments, on the upper side of L. scoriaceus, 18 
wanting. 

Obs. II-—I have drawn up the above description en- 
tirely from one of the Fonte Boa individuals, which is, 
I believe, a female; the individuals from Ega, of which 
several are before me, are slightly smaller, and show a 
slightly greater development of the punctures on the under 
side of hind body; but these differences are only very 
slight, and I believe all the individuals from both localities 
to be of one species. 


2. Leptochirus brunneoniger, Perty; Fauvel. 

Ega; two individuals. 

This appears to be a_ widely distributed, and yet but 
little variable, species. I see no difference between these 
Ega specimens and individuals from near Rio de Janeiro, 
and the species is recorded by Fauvel as Mexican. I have 
not myself seen any specimens from the north of the 
Amazons; on the other hand, an individual in my collec- 
tion is labelled “ Peru.” 


3. Leptochirus latro, n. sp. Niger, nitidus, thorace 
sanguineo; mandibulis brevibus; antennis crassiusculis ; 
vertice canaliculato, canalicula antice profunda, clypeo 


- 
422 My. D. Sharp’s Contributions to the 
parte posteriore elevata, anteriore abrupte decliva; ab- 
domine subtus magis punctato. Long. corp. 6 lin. 

Antenne short and stout, 13 lin. in length; the 10th 
joint hardly so long as broad. Mandibles short and stout, 
their upper edge strongly sinuate near the base. Head 
with the longitudinal channel as deep in front as behind ; 
the hind part of the elypeus elevated to the level of the 
vertex, and on the same plane with it, but quite distinctly 
marked out therefrom, the front part of the clypeus at 
right angles to the hind portion; the upper part of the 
head is black, with the neck obscurely reddish, beneath 
blackish-red. Thorax rather broad, red, 1 line in length, 
and quite 1} in breadth, Elytra narrower than the thorax, 
14 lin. in length, and just about the same in breadth, quite 
ASS Hind body black, moderately stout; on the under 
face, the segments 3—6 are coarsely punctured over a 
large space on each side the middle. Legs black, with the 
tarsi reddish. 

Ega; a single individual, of the male sex. 

Obs.—This species 1s closely allied to both L. brunneo- 
niger and L. maaillosus. The structure of the head and 
mandibles is almost the same as in the former species, but 
L. latro is smaller and has the thorax shorter, and the 
elytra black. The structure of the head distinguishes the 
species from L. maxillosus, and the shorter antennze dis- 
tinguish it from both the species alluded to. 


4. L. mavillosus (ab.). 

Ega; St. Paulo, about a dozen e xamples. 

I find great difficulty about this species ; indeed, 
seems to me probable that two or three variable and sf 
closely-allied species may be confounded in collections 
under this name. M. Fauvel has separated one form and 
given it the name of Z. proteus, but I have not been able 
to satisfy myself as to which of the forms his description 
refers. This author gives a figure of the front of the head 
of an insect he calls L. mazillosus (Notices Ent. pt. ii. 
pl. i. fig. 2), but I have seen no specimen at all like his 
figure. 

These Amazonian individuals vary much in size, colour, 
and also somewhat in the front of the head; but as I 
sannot see that these characters indicate distinct species, 
I think it best merely to record them as Z. mazillosus. 


Staphylinide of the Amazon Valley. 423 


TURELLUS, n. gen. 


Antenne clavate, 9-articulate. 
Tarsi omnes 4-articulati. 


Labrum ample, corneous; front margin rounded and 
serrated, the serrations being about twenty in number. 
Mandibles elongate, slender, acutely pointed, strongly 
curved, with an “elongate pointed tooth on the middle of 
the inner side of each. Maxillary palpi elongate; Ist 
joint not observed, 2nd joint rather long and slender, two 
or three times as long as broad; 3rd joint similar to 2nd, 
but nearly twice as “long; 4th joint large, longer than 
3rd, elongate oval, but a * good deal dilated on the inner 
side about the middle, 

Antenne inserted at the sides of the front, as in 
Oxytelus, short, 9-jomted; the 1st joint stout, joints 2—7 
small, each a little shorter than its predecessor; 8th joint 
strongly transverse, 9th joint forming a pointed oval club, 
terminating in sete. Head shaped as in Oxytelus ; the 
eyes rather small, but prominent. Prothorax strongly 
transverse, the base cut away on each side at the hind 
angles; beneath, the horny portions of the prosternum 
and sides occupy nearly the whole space, so that the front 
cox are nearly entirely covered; they are small, quite 
contiguous, placed quite at the hind part of the thorax, the 
openings of their cavities being apparently reduced to two 
minute, circular, contiguous (? confluent) spaces, without 
lateral prolongations. Middle coxee minute, nearly con- 
tiguous, subglobose. Elytra longitudinally costate. Hind 
body short and broad, much narrowed to the extremity, 
rather strongly margined, composed of six visible segments. 
Legs rather small, tibize slender and simple; tarsi short, 
4-jointed, the three basal joints short, and about equal to 
one another, the 4th joint rather longer than the three 
others together. Form of the whole insect—short and 
broad, flat on the upper side. 

This minute insect, for which I have been obliged to 
find a new generic name, is perhaps the most interesting 
of the Staphylinide discovered by Mr. Bates. Only 
a single individual was brought back by Mr. Bates, and 
I have therefore been able to expose its characters only in 
a very imperfect manner; the lower lip and its appendages 
and also the maxille and base of the maxillary palpi have 
quite eluded my observation, and also I have been able to 
see only in an imperfect manner the structure of the hind 
parts of the prosternum. Nevertheless, it is evident that 


424 Mr. D. Sharp’s Wot iBidinns to Staphylinide. 


the insect is one of the most anomalous of the Staphylinide, 
and that the determination of its nearest allies will be 
a matter of difficulty. The structure of the anterior 
coxal cavities, I anticipate, will be found to be very close 
to that which obtains in Thoraxophorus corticinus ; from 
that insect its trophi, however, remarkably separate it and 
appear to indicate a relationship with the anomalous genus 
Hvesthetus. [Lam unacquainted with the North American 
genera Hdaphus and Stictocranius, and am unable to 
guess what relationship it may bear thereto. Its nearest 
allies I cannot, therefore, at present point out. 


l. Turellus Batesi, n. sp. Obscure rufescens, opacus, 
antennis pedibusque testaceis, elytris tricostatis. Long. 
corp. + lin. 

Antenne yellow, about as long as head. Head a good 
deal narrower than the thorax, the front part in the middle 
rather largely depressed ; the depressed part triangular, 
and limited in front by the slightly raised and curvy ed edge 
of the clypeus, and on each side by an obscure raised line 
proceeding from the point of insertion of the antenne ; 
these two lines converge about the middle of the head, 
but do not quite meet with one another; the surface is 
opaque and dull, but has no distinct sculpture. Thorax 
quite as broad as the elytra, quite twice as broad as long ; 
the front margin a little sinuate on each side, the front 
angles not in the least deflexed, a little rounded, the short 
sides nearly straight; the hind margin a good deal cut 
away on each side, so as to leave a gap between the thorax 
and elytra at the sides; the surface not quite even, but 
with two indistinct, distant, longitudinal elevations; be- 
tween these, at the base, are three very minute and in- 
distinct fovez ; the surface quite dull, but with no distinct 
sculpture. Elytra broad, a good deal longer than the 
thorax, each with three raised, longitudinal lines, the 
inner one of which is the most distinct, and is placed 
about midway between the suture and side: the second 
is placed quite at the side, and the third, or outer one, 
which is near the second, is placed on the deflexed lateral 
portion of the wing case; the pleural portion of the wing 
case under this third line is abruptly inflexed and rather 
broad. The surface is dull, but without distinct sculp- 
ture. Hind body dull, without distinct sculpture. 

Kga; a single individual, whose sex I do not know.

V. Description of a new genus, and some new species, 
of Staphylinidee from Mexico and Central America. 
By D. Sharp, M.B. 


[Read 7th June, 1876. ] 


In this paper I give the descriptions of a few interesting 
new species of Staphylinide, which have been added to 
my collection by several naturalists; a few species were 
collected by Mr. Salvin during his visit to Central America, 
but only one of them can be described with advantage ; the 
most interesting species amongst Mr. Salvin’s captures 
was Leptochirus bicornis, Fauvel, of which two specimens 
were found in the Val de Fuego at an elevation of 6,400 
feet; this species is the only representative yet brought to 
light in the New World of a group of Leptochirus, which 
is represented by numerous species in the eastern tropics 
of the Old World. A small collection sent by Mr. Flohr 
from the city of Mexico to Mr. Bates proved to contain 
several novelties, as did also the very small but interesting 
collection of this family made by Mr. Belt during his 
residence at Chontales. 


Glenus coxalis,n. sp. Fulvus, capite thoraceque aureis, 
nitidis, hoe parce punctato; abdomine nigro, apice late 
rufo-testaceo. Long. corp. 18 mm. 

Mas: coxis posterioribus spina elongata, leviter curvata 
armatis. 

Antenne with the 3rd joit scarcely so long as the 2nd. 
Head rather broad and short, of a brilliant golden colour, 
rather coarsely but not densely punctured, the punctures 
more sparing near the front and along the middle. Thorax 
rather small, similar in colour to the head, about as long 
as broad ; the base and hind angles greatly rounded, the 
sides scarcely sinuate; the sides are only sparingly punc- 
tured, and there is a rather broad but not elevated space 
along the middle, without punctures. LElytra distinctly 
broader, but scarcely longer than the thorax; of a dark- 
tawny colour, quite dull, but only obsoletely punctured, 
and with a scanty golden pubescence. Hand body black,

with the 6th, 7th and apical segments yellow, rather 
sparingly and not coarsely punctured. Legs tawny, with 
the cox infuscate. The middle of the sternum also infus- 
cate. 

The male has the hind cox armed with an elongate 
spine, projecting backwards and slightly curved outwards ; 
the ventral plate of the 6th segment of the hind body has 
in the middle, near the base, two small patches of pale 
pubescence, separated by a narrow shining space, while 
the hind margin of the following segments has a mode- 
rately large excision in the middle. 

Panama; sent by Mr. Edwards of San Francisco. 

Obs.—This is a very distinct species, to be placed at 
one extremity of the genus, with G. vestitus and its allies 
at the other; the only individual I have seen has lost its 
antenne, except the three basal joints. 


SELMA (n. gen. Staphylininorum). 
Corpus pubescens. 
Antenne intus subserratee. 
Palpi omnes articulo ultimo dilatato. 
Thorax lineis lateralibus haud conjunctis. 


Mandibles rather short, sinuate on their inner margin 
towards the base, but without distinct tooth. Maxillary 
palpi with the first joint very short, 2nd stout, longer than 
broad, 3rd a good deal shorter than 2nd, but not quite so 
thick, 4th longer than any of the others, and a good 
deal dilated. Labial palpi with the two basal joints short 
and stout, the 3rd quite as long as the other two together 
and dilated from the base towards the apex ; mentum very 
short and very broad. Thorax with the side piece broad, 
and much produced inwardly over the spiracle, which is 
hence hidden; its lateral margin formed by the upper line, 
which is a good deal deflexed at the front angle, but only 
joins the lateral line on the front margin at the side of the 
neck. Middle coxe widely separated, and with a wide 
space between the meso- and meta-sternal processes. 
Dorsal segments of hind body without curved lines. Front 
tarsi dilated; front tibiz also broad and without spines ; 
middle and hind tarsi rather broad and flattened from 
above. 

The peculiar insect for which I propose this generic 
name has caused me great hesitation as to its affinities. 
I think on the whole the most probably correct place I can 


of Staphylinide from Mexico, &c. 427 


assign to it is in the neighbourhood of Plociopterus and. 
Brachydirus, though it is extremely different from those 
insects in appearance and in the structure of its palpi; 
I thought it probable at one time that it would prove to 
be allied to the Eastern Trichocosmetes and its neighbours, 
but the structure of the prothorax proves to be very different 
from what it is in the oriental forms mentioned, while the 
points it has in common therewith, such as the subserrate 
antenne and the narrow neck, are of much less primary 
importance. ‘Taking all into consideration, it appears to 
be a very isolated form. 


Selma modesta, n. sp. Nigra, opaca; dense, subtiliter 
punctata ; antennis apicem versus testaceis. Long. corp. 
14 mm. 


Antenne nearly black at the base, becoming paler 
towards the apex, the last three or four joints nearly en- 
tirely yellow; they are 4 mm. in length, and distinctly 
thickened towards the apex; joints 6 —10 with the upper 
inner angle acute; 3rd joint rather longer than 2nd; 10th 
scarcely so long as broad. Head short and broad, dis- 
tinctly narrower than the thorax ; the eyes large and con- 
vex, so that they only leave a small part at the hind angles 
unoccupied; the vertex is straight, and the neck scarcely 
half the width of the head; the upper surface is densely 
and evenly but not coarsely punctured, quite dull, but with 
very little pubescence, and has a minute fovea on the middle. 
Thorax about as long as broad, distinctly narrower than 
the elytra, the hind angles very indistinct ; the surface is 
extremely densely and rather finely punctured; it is quite 
dull, and bears a fine, depressed, dark, fuscous pubescence. 
Scutellum covered with a fine black pubescence. LElytra 
rather longer than the thorax, black, with an obscure 
brassy tinge, densely and finely punctured, but the punc- 
tuation very indistinct, except towards the humeral angles, 
where the very fine pubescence is more scanty. Hind 
body black, with a very indistinct brassy tinge, much nar- 
rowed towards the apex, densely and finely punctured, and 
with a very fine pubescence; the middle of each segment 
at the base, however, is only very sparingly punctured, so 
that when extended the hind body looks a little shining 
along the middle. The legs are black and rather short 
and stout; the tarsi pitchy; the basal joint of the hind foot 
broad, and quite as long as the three following together ; 
the tibize bear an ashy pubescence.

428 Mr. D. Sharp’s description of a new genus, §c. 


A single female, found at Chontales, has been given me 


by Mr. Belt. 


Xanthopygus viridipennis, n. sp. Niger, nitidus, an- 
tennis abdominisque segmentis duobus ultimis testaceis ; 
elytris viridis, vel cyaneo-viridis; abdomine sat crebre 
punctato. Long. corp. 15—16 mm. 

Mas: abdominis segmento 6° ventrali medio linea trans- 
versa longe pilosi, margineque apicali leviter emarginato, 
segmento 7° apice medio profunde inciso. 


“Allied to S. sapphirinus, Er., but rather narrower, and 
with longer thorax; the punctuation of the upper surface 
less dense, and the elytra greenish rather than blue or 
violet. The antennz are rather long and slender, entirely 
yellow. Maxillary palpi longer than in S. sapphirinus ; 
labrum pitchy. Head coarsely and irregularly punctured, 
with a broad impunctate space on the disc, the punctures 
not very numerous except behind the eyes. Thorax quite 
as long as broad, rather coarsely and irregularly punc- 
tured, the punctures moderately numerous. LElytra shghtly 
longer than the thorax, shining green or greenish-blue, 
moderately strongly and not closely punctur ed. The hind 
body is black, with the two last sezments entirely reddish- 
yellow, its punctuation moderately close and distinct. 
Legs black; front tarsi ferruginous. 

The characters of the male are similar to those of 
S. sapphirinus, but the emargination of the 6th segment 
is broader and not so deep. 

Chontales; Nicaragua. 


Philonthus discretus,n. sp. Niger, capite thoraceque 
subeneis; antennis crassiusculis, capite transversim sub- 
orbiculato ; thorace crebre fortiter punctato, linea lata im- 
punctata ; ‘elytris abdomineque crebre punctatis. Long. 
corp. 1O—11 mm. 


Antenne black, with the base of the 2nd joint red; 
rather stout, not thickened at the extremity; 3rd joint as 
long as 2nd; of 4—10 each is a little shorter than its pre- 
decessor; the 10th not quite as long as broad. Head 
small, a good deal narrower than the thorax, rounded, 
shorter than broad, bearing numerous deep and rather 
coarse punctures, which are “wanting on a space along the 
middle. Thorax rather narrower than the elytra, about 
as long as broad, the sides a little curved and a little 


of Staphylinide from Mexico, &c. 429 


narrowed towards:the front, bearing numerous deep punc- 
tures, which are wanting on a rather broad space along 
the middle. Elytra slightly longer than the thorax, closely 
and rather finely punctured. Hind body evenly, closely 
and moderately finely punctured. The middle cox are 
contiguous. 

In the male the front tarsi are very greatly dilated and 
farnished beneath with yellowish hairs, and the front tibize 
are broad and short. The ventral plate of the 7th segment 
of the hind body has a large and elongate excision, the 
anterior part of which is membranous; the 6th segment 
has a small rounded excision, and is longitudinally im- 
pressed in front of it. 

City of Mexico; two male individuals, sent by Mr. 
Flohr. 

Obs.—This species has a peculiar appearance, reminding 
one of the genus Staphylinus, and is remarkable by its 
robust front tibiz. I do not know of any near ally for it. 
The labium is small, and the ligula is entire. 


Philonthus Flohri,n.sp. Niger, capite, thorace, elytris- 
que leviter snescentibus; antennis gracilibus, articulis 
nullis transversis; thorace lateribus sinuatis, seriebus dor- 
salibus 4-punctatis elytris thorace longioribus, cum abdo- 
mine crebre punctatis, hoc subtus pubescentia pallida 
vestito. Long. corp. 13 mm. 

Mas: tarsis anterioribus modice dilatatis ; abdomine 
segmento 7° ventrali apice late minus profunde exciso. 

Fem.: tarsis anterioribus simplicibus. 

Antenne rather long and slender, black, scarcely at all 
thickened towards the extremity, all the joints elongate, 
even the 10th being longer than broad. Head broad and 
short, distinctly narrower than the thorax, with a pair of 
punctures on éach side between the eyes, and numerous 
others about the hind angles. Thorax about as long as 
broad, the sides very distinctly sinuate; the dorsal series 
consists of four punctures; there are other punctures along 
the margins, and also five punctures on each side near the 
front. Scutellum dull black, rather closely but obsoletely 
punctured. Elytra rather longer than the thorax, rather 
closely and distinctly, moderately finely punctured. Hind 
body very black, distinctly and only moderately closely 
punctured, and clothed with black hairs; the anterior 
segments without any trace of carina in the middle at their 


bases; beneath it is still more sparingly punctured, and the 


430 Mr. D. ShaisMenintigs of a new genus, &c. 


hairs are pale. The middle cox are moderately distant. 
The tarsi are slender, the basal joint on the hind ones is 
longer than the two following together. 

Five specimens, sent from the neighbourhood of the city 
of Mexico by Mr. Flohr, in whose honour I have named 
the species. 

Obs.— This species is just about the size of our P. eneus, 
but differs therefrom at the first glance by the elongate 
antenne. 


Philonthus mexicanus, n. sp. Niger, capite, thorace, 
elytrisque leviter enescentibus, pedibus piceo-testaceis ; 
antennis articulis nullis transversis; capite suborbiculato, 
thorace angustiore, hoc seriebus dorsalibus 4-punctatis ; 
abdomine nitidulo, parce punctato. Long. corp. 9— 
10 mm. 

Mas: tarsis anterioribus subdilatatis; abdomine seg- 
mento 7° ventrali apice triangulariter exciso. 

Antenne black, moderately long, scarcely at all thickened 
towards the extremity; the 10th joint is the shortest, and 
is slightly longer than broad. Head a good deal narrower 
than the thorax, shining and nearly black, with a pair of 
punctures on each side between the eyes, and others near 
the hind angles. Thorax narrower than the elytra, quite 
as long as broad, slightly narrowed towards the front ; 
obsoletely simuate at the sides, with a dorsal series of four 
punctures on each side the middle, and also with four 
punctures on each side towards the front, besides the small 
marginal punctures. Scutellum black, finely and not 
closely punctured. Elytra about as long as the thorax, 
rather closely and finely punctured. Hind body black 
and shining’, the segments both above and below only very 
sparingly punctured, but with rather numerous long sete. 
The legs are yellow, but greatly suffused with black, the 
yellow colour being most distinct on the upper faces of 
the femora ; the middle coxe are distinctly but not greatly 
separated. 

The male has a rather large triangular notch at the 
apex of the ventral plate of the 7th segment, but it is 
about half filled up by a membrane; the front tarsi of 
this sex are only a little dilated, and in the female they 
are simple. 

Eight individuals, sent from the city of Mexico by 
Mr. Flohr. 

Obs.—This species is a little larger than our P. varius, 


of Staphylinide from Mexico, &c. 431 


and has the head more orbiculate, and is remarkable by 
the sparing punctuation of the hind body. 


Tesba Belti, n. sp. Nigra, nitida, capite supra sub- 
opaco, dense rugoso-punctato, subtus cum lateribus parcis- 
sime punctato ; antennis articulis 4—10 valde transversis. 
Long. corp. 21 mm. 


Upper surface of head covered with dense, extremely 
coarse and deep punctures; the punctures at the hind 
angles, however, are only sparing, and at the sides behind 
the eyes are almost absent; its under surface is black and 
shining, and bears only a very few rather coarse punctures. 
The extreme apex of the hind body is distinctly reddish. 

Found by Mr. Belt at Chontales, and named after him. 

Obs.—This species almost exactly resembles 7’. Jati- 
cornis (Tr. Ent. Soc. 1876, p. 195), except in the sculpture 
of the head. 


Pederus Salvini, n. sp. Apterus; elongatus, niger, 
antennis palpisque testaceis, elytris viridi-ceruleis thorace 
multo minoribus. Long. corp. extens. 13—15 mm. 


Head broad and large, coarsely and moderately closely 
punctured, black and ‘shining ; antenne about as long as 
head and thorax, rather slender, yellow, 3rd joint very 
long, quite twice as long as 2nd; of 6—11 each is a little 
shorter than its predecessor, the 1ith being markedly 
shorter than the preceding one. Thorax large ‘and convex, 
the front and front angles greatly rounded, the sides much 
narrower towards the base; it is shining black, distinctly 
but neither coarsely nor closely punctured, with a broad 
space along the middle impunctate. Scutellum dull black, 
the exposed portion impunctate. LElytra a good deal 
shorter and narrower than the thorax, the shoulders very 
narrow; they are of a greenish or bluish colour, and bear 
coarse punctures, the interstices of which are very irregular 
and uneven. The hind body is black, and is rather 
sparingly but distinctly punctured. The legs are black, 
with the tarsi pitchy or pitchy-vellow; the front tarsi rather 
broad, and parallel-sided, distinctly more dilated in the 
male. 

The excision on the apical abdominal segment in the 
male is rather large and deep, and the segment preceding 
it is more closely punctured on the middle than elsewhere. 

Found at Aceytum, at an elevation of 5,100 feet, by 


432 Mr. D. Sharp Mesarision of a new genus, &c. 


Osbert Salvin, Esq., in whose honour I have named the 
species. 

Obs.—This species is allied to the Columbian P. rutili- 
cornis, but is very readily distinguished therefrom by its 
much shorter head and elytra. In size and form it is 
extremely similar to the Japanese P. Poweri, but its black 
legs and more punctured upper surface separate it decidedly 
therefrom. 


Osorius mundus, n. sp. Niger, nitidus, antennis pedi- 
busque rufis; thorace elytrisque parce punctatis, illo linea 
medio impunctata, minus discreta; abdomine crebre punc- 
tato. Long. corp. 7 mm. 


Antenne red, rather longer than the head, the five 
terminal joints distinctly thicker than the others. Clypeus 
almost straight in front. Head with coarse punctures, 
which near the eyes are elevated, the hind portion is with- 
out punctures, as is also a space along the middle. Thorax 
about as long as broad, greatly narrowed behind, shining 
black, with sparing, coarse punctures, which are absent 
from an indistinct space along the middle. Elytra slightly 
longer than the thorax, shining black, rather coarsely and 
sparingly punctured. Hind body rather closely punctured 
with rough punctures. Legs dark red. 

Two specimens, sent from the city of Mexico by 
Mr. Flohr. 

Obs.—This species is closely allied to the North 
American O. latipes, but is more than twice its size.

and by the absence of the longitudinal suleation on the 
dorsal surface of the tibize; from Aphthona* it is separated 
by the unarmed apices of the four anterior tibiz. 


Sutrea elegans.

eyes, the elevated portion forming a broad ill-defined carina, 
the apex of which is angulate ; encarpx subtrigonate, con- 
tiguous; antennz rather more than half the leneth of the 
body, slender, filiform, 3rd jomt much longer than the 2nd, 
outer joints stained with fuscous. Thorax more than three 
times as broad as long; sides rounded, slightly sinuate just

* Dr. Chapuis errs in stating that the four anterior tibiz in Aphthona 
are without apical spines; they are present in all the species that I have 
examined, but are frequently hidden by stiff hairs, and therefore difficult 
to discover without a good lens.

new genera and species of Halticine. 439 


Genus Arcorpus, Fischer. 


The insect described below differs from the hitherto 
described species of the genus in having the anterior 
margin of the clypeus entire, and not emarginate; it 
agrees, however, so completely in all other characters, in- 
cluding the spine at the apices of all the tibiz, that I have 
not hesitated in placing it in the genus.

Genus Eryrropacuys, Motsch. 
Bull. Mose. 1866, p. 419. 


This genus, formed by Motschoulsky on some Ceylon 
insects formerly placed by him in Aphthona, i is easily dis- 
tinguished from most other genera of Halticine by the 
absence of a spine at the apex of the posterior tibiw ; the 
hinder thighs are also much more slender than usual, and, 
in my opinion, it is doubtful whether its true position is in 
that group.

Lepidoptera. By W. H. Miskin. 


{Read 2nd August, 1876.] 


THE following notes, which I beg to lay before the Ento- 
mological Society, are descriptive of some insects recently 
added to my collection, that will, I believe, prove new to 
science :— 


Family PAPILIONID, Leach. 
Sub-family PaprLionIn®, Swainson. 
Genus Papizio, Linn. 
Papilio E-gipius, n. sp. 


Male-—UPrrerrsivE: black. Primaries: with a few 
short dashes of white, bordering on the costa near apex. 
Secondaries: with a broad sulphurish band embracing 
point of discal cell, on which side the edge of band is 
straight, and extending outwardly to within a short distance 
of outer margin, on which side it is crenulated between 
the nervules, touching anterior margin but not extending 
abdominally beyond third median branch; immediately 
above anal angle a single red lunule; outer margin of 
both wings crenated in white. 

UNDERSIDE: deep black. Primaries: with apical dashes 
almost obsolete. Secondaries: with a very small red spot 
at apical angle, same at anal angle surmounted by largish 
lunule of same colour; a large red lunule between second 
and third medians, a very small and imperfect one between 
first and second, and one barely perceptible between dis- 
coidal and first median, all near the margin. Antenne, 
head, thorax, and abdomen, all black above and below; 
the white specks between head and thorax very indistinct. 

Female.—UPPERSIDE. Primaries: with the whole of 
the basal region, the hinder and outer margins, and costa, 
all black; the veins widely black, and the spaces between 
with wide bands of black, excepting those between the 
second and third medians, and third median and sub- 
median, which are quite white; within the cell are also

several stripes of black, the rest of wing clouded white. 
Secondaries: black, with central spot of white nearly 
touching abdominal margin, digitate on outer side; a 
marginal row of red lunules, with a very large one above 
anal angle. 

Unpersivp: exactly as on upper, primaries rather 
whiter. Head, thorax, &e., as in male.

ee ee Bay, Queensland (Kuntsler). 

Coll. $ and 2, Queensland Museum; ¢, W. H. Miskin. 

This is a very distinct and well-defined species, which 
has never before, I believe, been met with. It belongs to 
the Hrectheus group, from the typical species of which it 
is at once distinguishable by its much smaller size, and 
particularly by the absence in the male of the subapical 
band in primaries, and of the blue markings and most of 
the red markings on underside of secondaries; and in the 
female by the much blacker appearance, the absence of 
the broad disco-cellular band, by the black bands between 
the nervures in primaries, the absence of the blue mark- 
ings, and by the limited area of white in the secondaries. 

The specimens from which my descriptions are taken 
were contained in a collection of insects made by Mr. H. 
Kuntsler at Rockingham Bay (Northern Cascais 
during the past season, and was the only new species 
amongst the Rhopalocera therein, although many others 
of much interest were included. <A representative of each 
sex has gone into our Museum collection; the other two 
specimens, both males, passed to my own. 


Family NY MPHALID&, Swainson. 
Sub-family Saryrrinz, Bates. 
Genus XENICA, Westwood. 
Xenica Kershaw, n. sp. 


UprersipE: deep brown, with markings all of rufous. 
Primaries : with two short, transverse bands within the 
cell, one about the middle, the other and larger one at 
extremity, another towards the apex, touching the costa ; 
an ocellus near apex ringed with rufous, with small white 
centre; above the ocellus three small spots, reaching the 
costa, below and touching the ocellus a large round spot 5 
three small, faint, submarginal spots from apex downwards; 
three large spots, the centre one of which is the largest, 
from near posterior angle upwards; a large spot immedi- 


of Australian Diurnal Lepidoptera. 453 


ately under and nearly touching central discal band; outer 
border fringed between the nervules with pale rufous, pos- 
terior margin edged with rufous. Secondaries: with large 


anal ocellus, ringed with rufous, white centre; a narrow, 


submarginal streak from base to anal angle, a shorter 
parallel one not reaching ocellus; a spot near base; a 
short, oblique band within cell; a curved, irregular band 
from costa nearly to ocellus, avoiding the cell; a round 
spot below apical angle, between this and ocellus two small, 
oblong patches; near the ocellus two submarginal lunules ; 
two small specks between ocellus and anal angle, sur- 
mounted by a larger one; fringed between nervules (which 
are conspicuously terminated in black) with pale rufous, 
base of both wings and abdominal margin of secondaries 
thickly clothed with long, pale-brown hairs; thorax black ; 
abdomen dark brown. 

Unpersipr. Primaries: very much as above, except 
that the ground is lighter; the rufous patches somewhat 
paler, the three towards hinder angle being connected to- 
gether; above the ocellus the small spots are whitish; a 
silvery submarginal band from apex more than half-way 
down the wing. Secondaries: with ground colour red- 
dish-brown, all the lighter markings being somewhat simi- 
larly disposed as on upperside, but silvery, and more 
extended ; the streaks parallel with abdominal border are 
four in number, one of which is marginal; the marks near 
outer margin here form a broken but almost connected 
border from apical to anal angles; basal and sub-basal 
patch, the latter extending from costa into and nearly 
across the cell; and ocellus on costal border near apex, 
similar to but rather smaller than anal one, which is here 
the same as on upperside; thorax and abdomen light 
brown. 

Secondaries somewhat angulated. 

Hxpanse; dct 2. 3525/1. 8. 

Hab.— Victoria (Kershaw). 

Coll. W. H. Miskin. 

This species is closely allied to X. Lathoniella (West- 
wood), but is abundantly distinct, both by its larger size, 
the angulated form of the secondaries, and particularly 
by the very different arrangement of the silver markings 
on the underside. I am indebted for my specimens to 
Mr. W. Kershaw, of Melbourne ( Victoria), who observes, 
‘* This species is found upon or at the foot of high moun- 
tains.” So far as my experience goes, I believe the species 
to be confined to the colony of Victoria.

Genus EPINEPHILE, Hiibner. 
Epinephile Rawnsleyi, n. sp. 
UprersipE: dark uniform brown. Primaries: with 
a black ocellus, with small, pale blue centre, near apex; a 
larger one of same description between second and third 
median branches, near margin. Secondaries: with an 
ocellus similar to “those on primaries, but widely encircled 
with ring of orange, near anal angle; a smaller one, also 
with orange ring, “but without the central speck of blue 
at apex. 
UNDERSIDE: as above, but with faint indication of discal 
band within the cell of primaries; a faint, whitish ring 
round both ocelli, and two transverse lines of same cha~ 
racter, one submarginal, the other inside of the ocelli. 
Secondaries: with the transverse lines much more de- 
cided, the apical ocellus with white centre. 
Thorax and abdomen almost black, above and below. 
Expanse 2” 2”. 
Hab.—Maroochey River, near Brisbane (Rawnsley). 


Coll. Miskin. 


My specimen I believe to be unique. It was collected 
and presented to me by my friend the late H. C. Rawnsley, 
Esq., to whose memory I propose to dedicate it. 


Genus Heteronymrnua, Wallener. 
Heteronympha Digglesi, n. sp. 


UprersIDE: bright reddish-fulvous, with black mark- 
ings. Primaries: with short broad transverse band at 
termination of cell just touching costa, a short transverse 
band within, and about centre of cell, connected with base 
of wing by a longitudinal band which gradually narrows 
to a point at base of wing; apex with a moderately wide 
margin extending along costa nearly to the principal dis- 

cal band, and about a “third of way down outer margin; 
midway down outer margin, an irregularly -shaped patch 
extending some distance towards disc and inclining up- 
wardly so as to partially encircle, apically, a small simple 
ocellus, the patch being connected with apical margin 
by a ae submarginal line, and continued along margin 
nearly to hinder angle, which latter is narrowly bordered ; ; 
a square patch on hinder margin near angle; a wide band 
on hinder margin nearly to base; a square patch between 
second and third submedians, nearly touching discal band. 
Secondaries: with outer margin, from apex, broadly bor- 


of Australian Diurnal Lepidoptera. 455 


dered to a little beyond the discocellular vein, thence to 
anal angle a submarginal line; between first and second 
submedians, near to cell, a small patch, and between this 
and outer margin (which it touches) a larger patch; near 
anal angle a well-defined ocellus, with ring of paler fulvous; 
between this and submarginal line, a short inner line from 
first to third submedians; abdominal margin pale brown. 

UNDERSIDE. Primaries: as on upperside, but paler ; 
apical dark markings more extended, and clouded brown, 
instead of black; ocellus nearly obsolete; discal longitudinal 
band indistinct. Secondaries: clouded brown; a broad band 
from centre of costa to cell, darker, with lilac hue; region 
margining median vein towards base and abdominal mar- 
gin, same colour; two indistinct ocelli near apex, and one 
towards anal angle. 

Eixpanse 2” 3”. 

Hab.—Brisbane (Queensland). 

Coll. Miskin. 


A very scarce species, resembling in its habits A. 
mirifica, in company with which very rare insect it has 
been occasionally taken; it seems to be confined to the 
Brisbane district, and is only found in dark spots in dense 
scrubs, where there is an undergrowth of low ferns. 

It has been suggested to me that this insect may prove 
to be the male of mirifica, the possibility of the correct- 
ness of which surmise I am not prepared entirely to deny, 
particularly as the various specimens collected have some- 
what the appearance of partaking of the character of oppo- 
site sexes respectively; but the captures of either species 
are too limited in number to permit of the arriving at any 
positive determinations of the point upon this ground. 
The very different appearance and markings of the two 
insects, however, will, I think, justify the assumption of 
specific distinction ; and I have therefore much pleasure in 
naming our insect in honour of my friend Mr. 8. Digeles, 
who was, I believe, the first to discover it.

IX. Descriptions of new species of Hymenopterous Insects 
of New Zealand, collected by C. M. WAKEFIELD, 
Ksq., principally in the neighbourhood of Canter- 
bury. By FREDERICK SMITH. 


{Read 7th June, 1876.] 


Turrry new species of Hymenoptera are described in the 
present paper, nearly all having been taken in the Canter- 
bury Province of the south Island; thus a large area is 
left much less carefully entomologically explored. It may, 
therefore, I think, be confidently expected that, when 
the north Island has been worked as well as the south, 
at least double the number at present discovered will 
be added to the Hymenopterous fauna of New Zealand. 
Captain Hutton, in his observations on the indigenous 
insects, observes, “the Hymenoptera are poorly repre- 
sented, about eighteen species only being yet known.” 
The addition now made to. the list increases it to forty- 
eight. 

The Hymenoptera are less diligently collected than the 
more popular orders, but I feel confident that the list will 
ultimately number, if it do not exceed, one hundred species. 
The Formicide must surely consist of more than five 
species, the number at present discovered, and the fossorial 
group will in all probability prove to be much more exten- 
sive. Of the bees but few species are known, but the 
genus Megachile must, I imagine, find some representa- 
tive species, since several have been found in Tasmania, 
and Australia has at present yielded about forty species. 
No species of Scolia has yet been discovered, although 
both the above-named countries have several indigenous 
representatives of the genus; these localities have also pro- 
duced many species of Mutillide, but not a single species 
has, to my knowledge, been found in New Zealand; not 
a single wasp has been taken, but I fully expect species of 
the genus Odynerus will be discovered, it being well repre- 
sented in Australia, and a few species have come from 
Tasmania likewise. 

Mr. Wakefield’s collection contained nearly all the 
species previously described, and two of Tenthredinide,

one being the Blennocampa adumbrata, Klug ; this may 
be the same insect recorded by Captain Hutton under the 
name of £&. cerasi; this European species has doubtless 
been imported with trees or flowers. In the Reise der 
Novara, Dr. Sichel has described a species of Prosopis, 
no doubt the first from New Zealand; three are added to 
the list in the present paper. It is somewhat remarkable 
that only one species of the family Zhynnide should have 
been discovered, Rhagigaster Novare, described by De 
Saussure; as vers Tasmania and Australia are rich in 
species. The genera Rhyssa, Mesostenus and Derecyrta, 
I believe are for the first time added to the Hymenopterous 
fauna of New Zealand, the first by one of the finest species 
of the genus hitherto discovered. 


TENTHREDINIDE. 


Fam. SIRICID. 
Derecyrta deceptus. (PI. LV. fig. 6.) 


Female.—Length 5 lines. Ferruginous, abdomen rufo- 
fulvous, variegated with yellowish-white. Head globose, 
shining, and with scattered punctures; a broad yellowish- 
white line round the orbits of the eyes, slightly interrupted 
at their vertex ; two lines of the same colour run longi- 
tudinally over the vertex, and unite with another line that 
borders its posterior margin; the clypeus and mandibles 
yellowish, the latter obliquely truncate, and with four black 
teeth; the flagellum black, except its basal joint and the 
curved scape, “both of which are ferruginous. Thorax: 
the prothorax forming a short neck; a line on each side 
of its posterior margin running to the base of the wings; 
two oblique stripes on the mesothorax inclining inwardly, 
and uniting with a transverse waved stripe at its basal 
margin, two spots on the scutellum and also the post- 
scutellum, yellowish-white ; wings fulvo-hyaline, the 
nervures ferruginous, the stigma fuscous ; a large yellowish 
spot beneath the wings, and the posterior cox pale 
beneath ; the legs pale ferruginous. Abdomen yellowish 
towards the base. 

Prof. Westwood has figured three species of this genus 
in his “ Thesaurus Entomologicus Oxoniensis,” two of 
which are from Brazil, the other from Chili. This species 
bears a very strong resemblance to Tenthredo nassata ot 
Linneeus.

ginous, the later palest ; usually a minute ferruginous spot 
on the scape in front, sometimes obsolete. Thorax: the 
lateral margins of the prothorax, the scutellum, post- 
scutellum, sometimes a spot also on the disk of the meso- 
thorax, yellow or reddish-yellow ; two ovate yellow spots

X. Descriptions of three new species of Hymenoptera 
(Formicidz) from New Zealand. By FREDERICK 
SMITH. 


[Read 6th September, 1876.] 


Srnce the description of Mr. Wakefield’s collection was 
in the press, three new and interesting species of Formi- 
cide have been sent to me by Mr. David Sharp; two 
belonging to genera not previously ascertained to inhabit 
New Zealand, namely, Amblyopone and Ponera ; the type 
of the former genus is figured in Wiegm. Archiv. (1842), 
pl. vil. fig. 21, 3. The type of the genus Orectogna- 
thus is figured in the Trans. Ent. Soc. Lond. (1852, 
1853), pl. 21, fig. 9, ¥.

thin sericeous pile. Thorax oblong-ovate and very finely 
punctured, shining and finely pubescent; legs red, the 
calcaria pale testaceous. Abdomen smooth and shining, 
the apex rufo-testaceous, having a thin sericeous pile and 
a mixture of longer scattered pubescence ; the node of the 
abdomen wedge-shaped, compressed above, with its upper 
margin rounded. 

Worker.—Rather smaller than the female and of a 
brighter red, but closely resembling that sex; thorax 
elongate, attenuated at the base of the metathorax, which 
is as long as the pro- and meso-thorax, entirely smooth and 
shining; the node of the abdomen as in the female, the 
claws of the tarsi simple in both sexes.

490 Mr. F. Smith’s descriptions of new species 


Amblyopone cephatlotes. 


Worker.—Length 4 lines. Black, with obscure rufo- 
piceous tints; the mandibles, antennz and legs ferru- 
ginous. Head more than twice the width of the pro- 
thorax, subquadrate with the posterior angles rounded, 
the anterior margin narrowly obscurely rufo-piceous, a 
deep central channel anteriorly, extending from the inser- 
tion of the antenne to the middle of the head ; longitudi- 
nally striated, excepting the central and posterior areas, 
which are somewhat distantly punctured. Thorax elon- 
gate, shining, strangulated in the middle; the prothorax 
subglobose and distantly punctured; the mesothorax 
abbreviated ; the metathorax elongate, narrower than the 
prothorax, the sides nearly parallel, obliquely truncate 
posteriorly ; shining and distantly punctured. Abdomen 
smooth and shining; the first segment or node subglobose; 
the two following large, the second largest, both very 
convex and rounded; the apex of the abdomen rufo- 
piceous. 

This species is very distinct from Amblyopone australis, 
the type of the genus, described by Erichson in Wiegm. 
Archiv. 1842; it is most closely allied to A. obscura, 
Smith, Cat. Form. 109. Erichson gives the number of 
the joints of the antennz in this genus as 11-articulate ; 
in the figure given of the type, they are represented 
12-articulate, and this is the true number both in the 
female and worker, the male having, as usual, an additional 
joint.

The genus Orectognathus was established by myself in 
the year 1854, in the ‘* Transactions of the Entomological 
Society,” vol. ii., New Series, 1852—1854, on a species 
of which only a few workers had been obtained in New 
Zealand; a second species has been found at Tairua by 
Captain Brown: an examination of the latter renders it 
necessary to give the generic characters with some impor- 
tant additions. 

There are four genera of ants, all bearing a general 
facial resemblance; these are, Daceton, Perty ; Cerato- 
basis, Smith, and Strumigenys, Smith, all from Brazil ; 
the genus Orectognathus, of New Zealand, being the 
fourth. Winged females of the two first genera are 
known; and although the neuration of the anterior wing 


of Formicide from New Zealand. 491 


is similar in some degree, yet, as in Cerotobasis, all the 
discoidal cells are wanting, and the structure of the an- 
tenn so very different, their distinction is definite. Stru- 
migenys is separated from the foregoing by having only 
six joints in the antenne of the female and worker; the 
winged female not known. Orectognathus has 5-jointed 
antenne, the male is not known ; the female has not been 
taken in a winged state. 


Genus ORECTOGNATHUS, Smith. 


Head heart-shaped, deeply emarginate behind; man- 
dibles porrect, bifureate at their apex, near to which is a 
sharp tooth or spine; eyes lateral, of moderate size, and 
composed of a number of circular, convex, separated facets; 
antenne inserted forwards on the head, being 5-jointed in 
the workers and females. Thorax oblong, much narrower 
than the head, widest anteriorly, and with a short, acute 
tooth at the margins of the prothorax; the mesothorax 
has also a small lateral tooth; the metathorax with two 
acute spines; lees simple. Abdomen ovate and binodose ; 
the first node petiolated and clavate, the second globose. 


Orectognathus perplexus. 


Female.— Length 14 line. Pale ferruginous, the head 
closely and finely punctured; antennze and mandibles paler 
than the head. Thorax shorter and narrower than the 
head; the prothorax rounded in front; the scutellum with 
the hinder margin rounded, somewhat projecting over 
the metathorax, which is armed with two compressed, 
acute spines; the entire thorax closely and finely punc- 
tured; the legs paler than the thorax; the anterior tibize 
with a spine at their apex, the intermediate and posterior - 
pair simple. Abdomen slightly ovate, nearly globose; the 
first node petiolated and rounded, the second semi-globose, 
forming apparently the base of the abdomen. 

Worker.—The same size as the female, differing prin- 
cipally in the form of the thorax, the anterior margin of 
the prothorax being rounded; the sides oblique, the upper 
surface being kite-shaped and posteriorly truncate, the 
angles of the truncation being armed with a spine; closely 
and finely punctured above; the legs and abdomen as in 
the female.

In this species, the relative proportions of the joints of 
the antennz differ from those of the type of the genus 
O. antennatus, in which the second joint of the flagellum 
is longer than the two apical joints, but in the present 
species the three basal joints are nearly of equal length, 
and the three united only a little longer than the apical 
joint ; the general facies of the insect and the number 
of joints are the same,

XI. Descriptions of some new exotic species of Cole- 
opterous Insects. By J. O. Westwoop, M.A., 
F.L.S., &c., Pres. Ent. Soc. 


{Read 7th June, 1876.] 


AMONGST the recent additions to the Hopeian Museum 
at Oxford the private collections of various families of 
Coleopterous insects, made by Mr. Wallace in the 
Malayan Archipelago, are especially to be noticed, in- 
cluding the different groups of Malacoderm beetles. 
Amongst these insects were found several of considerable 
interest, some of which it is the object of this paper to 
describe. 


Family CLERIDZ. 
Genus nov. ANISOPHYLLUS. 


Corpus elongatum, depressum, obscurum, setosum. 

Caput mediocre. Labrum subbilobatum, setigerum. 
Mandibule elongate, falciformes, intus dente medio acuto 
armate. Maxillee bilobate, lobis elongatis, truncatis, setosis. 
Palpi maxillares subfiliformes, articulo ultimo subcylin- 
drico, apice oblique truncato. Labium apice dilatatum, an- 
gulis anticis rotundatis, palpis labialibus elongatis, subfilifor- 
mibus, setis longis instructis. Antennz longitudini elytro- 
rum xquales, articulis 3tio—8vo antice in denticulum 
sensim elongatum productis ; articulo 9no ramum longum 
planum e basi emittente, articulis 10mo et 11mo planis, 
latis, elongatis, 10mo apice in angulum porrecto, 1lmo 
simplici. Prothorax subquadratus, parum depressus, pos- 
tice parum latior. LElytra elongata, subdepressa, pro- 
thorace parum latiora, apice rotundata. Pedes mediocres,

producto, articulis 2do et 3tio longioribus, subtus in lobum 
productis, 4to brevi; 5to longiore; ungues tarsorum basi 
intus dilatati. 

This genus is allied to Enoplium, but differs from it, 
and indeed from all known Coleoptera, in the elongated 
branch of the 9th joint of the antenne, whilst the 10th 
joint is not furnished with a similar branch, but is simply

Family TELEPHORID&. 
Genus nov. ASTYCHINA. 


Corpus parvum, depressum, nitidum, subcoriaceum. 

Caput transversum, subconvexum. Labrum minutum, 
membranaceum, semi-rotundatum, medio antice emargina- 
tum. Mandibule graciles, acutissime, falciformes. Maxillee 
bilobate. Palpi maxillares filiformes. Labium subovale, 
minutum, membranaceum. Palpi labiales modice elongati, 
articulo ultimo basin versus incrassato, apice attenuato. An- 
tenn elytris breviores, articulo 3tio praecedenti fere triplo 
longiori, articulis 4to—9um sensim paullo crassioribus, arti- 
culo 10mo difformi, extus rotundato, intus in lobum parvum 
reflexum ante apicem producto (in uno sexu ¢ ? incrassato

rotundatis. Elytra elongata, parallela, subdepressa. Pedes 
graciles, tarsis articulo 4to subtus bilobato, unguibus tar- 
sorum basi dilatatis. 


This genus is allied to Podabrus, but the antennz ex- 
hibit a very anomalous structure, the two terminal joints 
in one sex forming what appears to be a remarkable pre- 
hensile apparatus, different from anything which I have 
elsewhere noticed in the insect world, but of which some 
analogous forms occur in some of the Entomostracous 
Crustacea.

XII. Note Dipterologice. No. 1.—Bombylii at Pompeii. 
By J. O. Wesrwoop, M.A., Hon. M. Ent. 
Soc. France, &c., Pres. Ent. Soc. 


{Read ist March, 1876.] 


THE youngest Entomologist cannot but have observed 
with pleasure, in the spring months, the interesting flight 
and movements of the two-winged flies belonging to the 
genus Bombylius. In the hottest sunshine some of these 
flies are to be seen suspended, as it were, in the air, im- 
moveably, the movements of the wings being so rapid as 
to render them invisible; but at once distinguishable by 
their long and slender black proboscis, stretched out in 
front of the head, and equalling in length the entire body of 
the insect. Other individuals may be seen flying over hot 
sandy banks, searching about the entrance of every hole 
and crevice. Hach of these particular movements has a 
very distinct object, the former insects being the males, 
which do nothing but revel in the sun-beams, whilst the 
latter are the females, seeking for the nest of some luck- 
less bee, already furnished with a supply of food for the 
larva of the bee, when hatched from the egg already de- 
posited by the hard-working female bee in her cell. 
Thanks to the researches of previous observers, the eco- 
nomy and transformations of the Bombylit are now satis- 
factorily known to Entomologists. Liatreille rightly con- 
sidered that the Bombylii, like Anthrax, were parasites, 
contrary to the opinion of Zetterstedt that the larvee feed 
on the roots of plants (Ins. Lapp. p. 510). The pupa of 
Bomb. major was first figured by M. Imhoff in the Isis 
for 1834, having been found by him in a situation which 
he had previously noticed to be frequented by Andrena 
humilis (vol. 1834, p. 536, pl. xii). In my Introduction 
(vol. 2, p. 538, 1840), I published a figure of the same 
pupa from a specimen discovered by Mr. C. Pickering in 
a sandy gravel pit at Coombe Wood on the 28th of March, 
from which the imago was produced in a few days. The 
pupa is very similar to those of the species of Anthraz, 
which are known to be parasites, having the front and 
underside of the head armed with strong spines, and the

- 
498 Prof. J. O. Westwood’s Note 


dorsal segments of the abdomen furnished with transverse 
rows of strong reflexed hooklets. In 1852, M. H. Lucas 
published the description of a new Algerine species of the 
genus, Bomb. Boghariensis in the Annales of the French 
Entomological Society, 2nd ser. vol. x. p. 11, pl. 1, 
No. II., which he had reared from a pupa found under a 
stone in a damp sandy situation, and, contrary to the opinion 
of Latreille, he expressed himself thus: “je suis porté a 
croire que les larves qui composent ce genre ne sont pas 
parasites, comme le supposent Latreille et beaucoup d’autres 
Entomologistes, mais qu’elles vivent au contraire isolément 
dans la terre,—opinion, au reste, qui avait déja été émise, 
mais avec doute, par M. Macquart, et que mon observa- 
tion vient confirmer.” 

In 1858 the real history of the Bombylius was discovered 
by the veteran Léon Dufour, who in the spring found 
various exuviz of the pupa of B. major sticking out of the 
ground, together with the newly-hatched insect, in places 
much frequented by various Andrenide, especially Colletes 
hirta, and who succeeded in the autumn, by digging on 
the spot, to find the larva “au milieu des déblais, ot 
gisaient par-ci par-la des coques de Colletes.” (Ann. Soe. 
Ent. France, 3rd ser. tom. vi. p. 505, pl. 13, fig. 111, 
and details.) The larva is elongated, apod and fleshy, 
and of a white colour. The preceding observations clearly 
prove that the larvee of the Bombylii are parasites in the 
nests of other insects, in the manner of the cuckoo among 
birds ; and the observation which has been the cause of my 
troubling the Society with this communication, although 
confirmatory of the discovery of M. L. Dufour, is more 
interesting from the situation in which it was made than 
from any additional knowledge which it affords. 

Those persons who have had the great pleasure of visit- 
ing Pompeii are aware that the whole area of the inclosure, 
streets, temples, houses and Forum of that most remark- 
able city, are throughout paved with stones of various sizes, 
from the large blocks which form the stepping-stones across 
the streets, to the minute cubes with which the tessellated 
pavements of most of the houses are ornamented in so 
beautiful a manner; the only exception being the Forum 
Triangulare, adjoining the Theatre, at the south-east angle 
of the city. In this Forum the surface is unpaved ; and on 
visiting it on several occasions, in brilliant sunny weather 
in the month of April, I was at once struck with a loud 
buzzing noise, just like that made by a swarm of bees, 


on Bombylit at Pompeii. 499 


On looking about to see what was the cause of this noise, 
I immediately perceived that the whole area was swarming 
with great numbers of Bombylius medius, which were flying 
about all over the surface (not hovering in the air), care- 
fully examining every crevice and hole. With them were 
an equal number of a large species of Andrena (of which 
I was not able to capture a specimen), engaged in making 
the burrows for their nests; and it was evident that the 
Bombylii were engaged in finding out the already-provi- 
sioned nests in which to deposit their eggs. Fortunately 
T also discovered (sticking nearly out of the ground) the 
exuvia of a pupa of the Bombylius, just in the same 
manner as the cast pupa skin of a Cossus or Zeuzera is 
seen sticking out of the trunks of trees, or still more 
closely as the pupa of a Hepialus or Tipula, which are 
often found partially exserted above the surface of the 
eround, the pupa of the Bombylius being thus shown to 
have the instinct to force its way to the surface of the 
ground before assuming the imago state, by the help of the 
numerous spines with which the segments of the body are 
dorsally armed, and which, being directed backwards, 
allow the insect to work upwards and prevent it, in its 
advancing progress, from slipping backwards.

some new exotic species of Tipulide. By J. O. 
Westrwoop, M.A., &c., Pres. Ent. Soc. 


[Read ist March, 1876. ] 


Tue family Tipulide in its widest extent comprises species | 
which exhibit a wonderful series of modifications in the 
structure of the antenne, and especially in the arrange- 
ment of the wing-veins. Many years ago I described 
some interesting forms, allied to the more typical T’%pule, 
in the Philosophical Magazine* and in the Zoological 
Journal ;+ and on the present occasion I have described 
and figured some curious species of the same division with 
which our collections have more recently been enriched, 
including some of the most gigantic Dipterous insects 
hitherto recorded, the wings of one of the species measuring 
not less than four inches in expanse, and others more than 
three inches, whilst the legs of some of the species are dis- 
proportionately elongated.

The outer dark brown apical fascia extends from the 
tip of the wing across the terminal veins and the apical 
margins of the small subapical and posterior discoidal cell, 
uniting with the dark-clouded posterior longitudinal dis- 
coidal vein, which is clouded with brown throughout its 
whole length to the posterior margin of the wing. 

I have referred this insect to the genus Ozodicera, Mcq. 
(= Hemicteina, Westw. Zool. Journ. vol. v. p. 450), on 
account of the similar arrangement of the wing veins, and 
the slightly ramose structure of the 3rd and five following 
joints of the antennz. In the species here described, how- 
ever, each of these joints emits two short slender branches, 
and the filiform terminal part of the antennz consists of 
six joints (fifteen in all), whereas in the Brazilian type of 
the genus ( Oz. gracilis, Westw., 1. c.) there are only single 
branchlets emitted from the intermediate joints, and the 
terminal portion only consists of four joints (or thirteen 
in all).

The head and thorax are clothed with a fine sericeous 
coating, giving them a greyish colour. The wings are 
fulvous, the anterior margin being rather more deeply 
coloured. The veins are dark fulvous, having a moderate- 
sized brownish patch towards the base, followed by a small, 
nearly central spot, and an irregular and much broken 
bar between the middle and apex of the wings. The legs 
are comparatively thick, and covered with fine, short 
hairs. The halteres are luteous buff. 


Genus nov. LIBNOTES.

vissimo, reliquis sensim attenuatis, singulo setam longam 
supra emittenti. Thorax compressus. Abdomen breve, de- 
pressum, thorace duplo longius. Al elongate, angusti, 
venis in parte apicali alarum simplicibus (nec furcatis), 
parallelis; venis analibus gracillimis versus basin curvatis, 
vend cubitali unica integra, venis tribus externo-medianis 
e cellulé oblonga ordinaria exeuntibus. 

Obs.—The venation of the wings in this genus is quite 
unlike that of any other Tipulideous insect with which I 
am acquainted. Its peculiarities will be best understood 
by a reference to the figure of the wing (fig. 6D). Itis 
not easy to speculate on the near affinities of so anomalous 
an insect.

XIV. Note Dipterologice. No.3.—Descriptions of new 
genera and species of the family Acroceride. By 
J. O. Westwoop, M.A., F.L.S., &c., Pres. Ent. 
Soc. 


[Read 6th September, 1876.] 


Tue family Acroceride is remarkable for the singular 
inflated bodies of many of the species, whence the sectional 
name of Vestculosa has been given to the group. The 
various structural modifications exhibited by the different 
genera are of great interest ; thus the antennz are very 
distinct and porrected in many species, whilst they are so 
small as to be scarcely visible in others. The proboscis 
in some is considerably longer than the entire body, whilst 
in others it appears to be absolutely wanting. The veining 
of the wings is also most singularly modified ; the veins in 
some species being almost obsolete and scarcely dis- 
cernible,* whilst the singular hunchbacked form of some 
of the groups, especially Philopota and Megalybus, is quite 
unique. . 

The species were collected into a monograph by the 
lamented Dr. Erichson, published in his ** Entomographien” 
in 1840, which I supplemented by descriptions of nineteen 
additional species in the 5th volume of our ‘‘ Transactions,” 
since which time various isolated additions have been 
made to the group. 

The following is a list of the new genera and species 
described in this paper :— 


Panops Lamarckianus. Pterodontia dimidiata. 
Lasia nea. Pialea ? lutescens. 

»  eneiventris. Pialeoidea magna. 

» nhigripes. Nothra bicolor. 

3, bicolor. Astomella apiformis. 
Apsona muscaria. 3 bombiformis. 
Leucopsina Odyneroides., Ogcodes Darwinii. 
Megalybus pictus. »  Fortnumi. 


= tristis. »,  Lasmannica, 
+ gracilis. »  ignava. 
subeylindricus. Leptynoma sericea. 


* The comparative study of the veins of the wings in this family is 
productive of striking results with reference to the system of venation 
throughout the order Diptera. This subject will probably form one of my 
series of Vote Dipterologice.

Genus Panorps, Lamarck, Latr. 
Panops Lamarchianus. (PI. V. fig. 1 and details.) 


Nigro-subcyaneus, thorace antice cum lateribus dense 
luteo-pubescentibus; antennis totis nigris, capite duplo 
longioribus, articulo ultimo longo, tenui, filiformi, apice 
subacuminato; abdominis lateribus cum ventre obscure

linea externa nigris; ocellis parum distinctis, in tuberculum 
vix elevatum positis; thoracis dorso convexo integro, squa- 
mulis concoloribus; abdominis segmentis continuis, fere 
nudis; alis fuscis, cellulé minima quadraté ad apicem 
cellule: median angustee ; squamulis obscure albis. 

Long. corp. lin. 55; expans. alar, lin. 11. 

Habitat Moreton Bay, Australia. In Mus. Hopeiano 
Oxonie. 


This species differs from P. flavipes (Latr. Enc. Méth. 
viii. p. 710) in its slender filiform antenna, its convex 
thorax destitute of longitudinal impressions, and its general 
colour. Like that species it has a minute supplemental 
cell on the disc of the wings at the end of the long, central, 
narrow, discoidal cell; but in the unique specimen in the 
Hopeian collection the cell is of unequal size in the two 
wings. Fig. 1d represents the wing on the right side of the 
body, and fig. le the veins of the characteristic part of the 
wing on the left side. The length of the wings equals that 
of the head, thorax and half the abdomen, and the proboscis 
reaches to the middle of the abdomen. 


Genus Lasta, Wiedemann, Erichson. 
Panops, Macquart, Wiedemann (olim), Guérin, Blanchard. 


The species of this genus are distinguished from those 
of Panops, (with which they are united by the French 
authors) by their geographical range (bemg confined to 
South America), their metallic colours, and the position 
of their antenne. 

The species hitherto described are— 


1. L. flavitarsis, Wied., Macquart, Erichson. (ame- 
thystina, Perty, pl. 36, fig.7; Beris? violaceus, G. R. Gray,

The names here employed for this genus and its four

script when purchased, and have been retained, although, 
I believe, they have never been published. The latter 
species, by their remarkably gibbose thorax, approach the 
genus Systropus, which, after all, may possibly be a most 
aberrant form of Acroceride.

This species agrees with the general character of Pialea, 
as laid down by ‘EB richson, but the antennz are affixed on 
the underside of a tubercle in the middle of the face 
between the eyes and are deflexed, and the wings have a 
veinlet extending from the apex of the narrow antero- 
discoidal cell to the hind margin of the wings (fig. 2c*); 
this veinlet is wanting in the unique species described and 
figured by Erichson.

XY. Notes of the habits of a Lepidopterous Insect 
parasitic on Fulgora candelaria. By J. C. 
Bowrinea, Esq. With a description of the species. 
By J. O. Westwoop, M.A., F.L.S.,. Pres. 
Ent. Soc. 


[Read 2nd August, 1876.] 


Ir is now twenty-six years since Mr. J. C. Bowring 
brought to England from Hong Kong specimens of a 
‘curious Coccus-like insect, parasitic on Fulgora can- 
delaria,” which he deposited in the British Museum. On 
his return to China he endeavoured to rear the insect to 
the perfect state, which he succeeded in doing in June, 
1850, the parasite in question proving to be the larva of 
a Lepidopterous insect. On the discovery being made, 
he forwarded further specimens to England, accompanied 
by the following notes :— 

“ No. 1 is a young larva. These are found from the 
size of a pin’s head to fully half an inch in length attached 
to the dorsal surface of the Fulgora, there being rarely 
more than one parasite on a Fulgora, although in one 
instance I found three on a single specimen. When 
young they are destitute of the cottony covering which 
gives them so great a resemblance to several species of 
Cocci; but as they grow larger this makes its appearance, 
until they are at length densely covered with it. Arrived 
at this stage, they drop off from the Fulgore, and retire 
to some safe place where they may undergo their transfor- 
mation to the pupa state. (No. 2.) Although I have 
not been able to discover in what way the insect spins its 
coating of cotton into a cocoon, it is evident that it does 
so, forming a comfortable-looking compact nidus, lmed 
internally with strong and stiff material. (See No. 3, a 
cocoon cut open and the pupa No. 4 extracted.) The 
period during which the insect remains in the pupa state ° 
1s very variable; in one instance it was only nine days— 
in another upwards of twelve months; the latter case was 
during our cool season, the former last month (June, 1850).

520 = Prof. J. O. Westwood’s Notes of the habits 


On attaining the perfect state (No. 6), the insect makes its 
escape from its nidus by an opening at one end, leaving 
the pupa case protruding therefrom about half its length 
(see No. 5), like the Octhetic?. The six specimens above 
mentioned show the insect in all its principal stages; the 
eggs I have not yet seen. My breeding-cage is a large 
one, with gauze sides and gauze top, and in this I keep 
my Fulgore, which require to be kept constantly supplied 
with fresh branches of trees on which they feed, by 
thrusting their rostrum into the bark. As before men- 
tioned, the parasites, when full grown, drop from the 
insect on which they have been living, and I find that 
they generally creep to the top of the cage, remaining 
back downwards. For the first day or two I can dis- 
tinguish the naked underside of the insect against the 
gauze, but its coating of cotton grows thicker and thicker 
until the larva disappears totally enveloped in its warm 
nidus. My first specimen came out in March. On 
taking my morning look at the cage, I observed with 
pleasure that one of my little parasites had attained the 
perfect state; for there were the cocoon and pupa case 
before me. I searched carefully for the imago, which 
I fully expected would prove a Curculio, but I found 
nothing but a small moth already dead. This was by no 
means satisfactory, as the beetle, if it were one, might 
have eaten its way through the gauze, and the moth 
might have been brought in with the fresh leaves the 
previous day. I therefore took another specimen, which 
had just assumed the pupa state, and enclosed it in a small 
tin box, which shut closely, and whose lid was pierced 
with a number of minute holes to admit the air. There 
could be no mistake now, and night and morning I 
examined the box. On the 9th day I was delighted at 
observing that the imago had come forth. This time 
there could be no doubt, for a beautiful little moth, already 
dead, was lying by the cocoon, similar in every respect to 
the one I had formerly found in the cage. Nos. 5 and 6 
are the cocoon and imago in question. I have to request 
that this series of specimens may be presented to the 
National Museum after being exhibited to the members 
of the Society. The larvee themselves are not common ; 
the specimen ‘labelled 2 I consider particularly interesting. 
I had it in my box for some time, when one day a number 
of Hymenoptera issued from it, parasites on a parasite. 


of a Lepidopterous Insect. 521 


I was unable, to my regret, to capture any of these, for 
they were so small that they escaped through the gauze 
covering of my breeding-cage, and I did not perceive 
them until it was too late.” 

The special interest attached to this insect consists, 
first, in its being a Lepidopterous parasite, and, second, on 
its being parasitic upon so remarkable an insect as the 
Fulgora candelaria. Mr. Bowring, it will be noticed, 
leaves untouched the nature of the parasitism of this 
species; but it is evident from what he says that the 
Fulgore ave not destroyed by the parasite. The following, 
in the absence of positive information, may probably be 
assumed to be the modus operandi of the insect. The 
Fulgora belongs to an order of insects (the Homoptera), 
of which many of the species secrete a greater or less 
quantity of white waxy matter, sometimes completely 
enveloping the body and sometimes forming elongated 
flakes, even several inches in length (e g., Lystra 
auricoma, Burmeister, Gen. Ins., pl. 20). 

Mr. Bowring states that his parasites were covered with 
a cottony coat, which gives them a resemblance to a 
Coccus. Now this “cottony” covering was doubtless 
formed of the wax secreted by the Fulgora; and I have, 
moreover, not the least doubt that it was upon the same 
waxy material that the parasite fed, without in any 
way injuring the Fulgora. That the larve of certain 
Lepidopterous insects feed upon various animal matters 
we know well. Hair, wool, fur, bones, &c. are all eaten 
by the larvee of different moths, and the moth “ fretting a 
garment” is a well-known symbol. We know, moreover, 
that there are two or three different moths belonging to 
the genus Galleria, of which the caterpillars feed on wax ; 
and although they are not immediately related to the 
present parasite in the perfect state, they afford, I think, 
sufficient grounds for our believing that it is upon the 
waxy secretion of the Fulgora that this parasite subsists. 

The accompanying figures are drawn from Mr. Bow- 
ring’s specimens, above described, in the British Museum, 
and others subsequently forwarded by that gentleman, now 
in the Hopeian Collection at Oxford, by whom also the 
manuscript name, subsequently adopted in this paper, 
was proposed, no description of the insect having hitherto 
appeared, so far as I am aware.

of a Lepidopterous Insect. 523 


The general appearance of this moth approaches nearest 
to the Arctiide ; its habits are, however, far removed from 
those of any known species of that family. As a wax 
feeder it agrees with the Gallerie, but its general cha- 
racter removes it far from that group. The Huplocami 
amongst the Tineide, which contains a number of sack- 
bearing species, have the antenne bipectinated, but their 
general character is equally removed from that of Epipy- 
rops. The sack-bearing habits of the Psychides may 
indicate a nearer approach to this insect, which has, how- 
ever, very little of the habit of that group. The arrange- 
ment of the veins of the fore-wings is interesting, the 
median vein having apparently four branches, as in 
Papilio, and the postcostal vein has apparently only four 
branches, but the normal number of branches to these 
veins exists—namely, five branches to the postcostal, and 
three branches to the median, with two intermediate veins 
(or rather branches) which correspond with the upper 
discoidal vein of E. Doubleday (which I consider normally 
to belong to the postcostal system) (fig. 15, 6 5*), and the 
lower discoidal of E. Doubleday (which I consider nor- 
mally to belong—as here seen—to the median system) 
(fig. 15, ¢ 3*).

XVI. Monograph of the British species belonging to the 
Hemiptera-Homoptera, family Psyllidx; together 
with the description of a genus which may be ex- 
pected to occur in Britain. By JOHN Scort. 


[Read Ist March, 1876.] 


J Ave been induced to undertake the present Monograph 
for two reasons, viz.: first, because such a thing has not 
previously been attempted, and I therefore thought it 
desirable for the sake of science to bring together and de- 
scribe all those species in my own collection as well as 
those in the collections of others which have been kindly 
lent for this purpose; secondly, because the Catalogue now 
in course of publication by the Entomological Society of 
London will thus be rendered more complete. I have also 
added translations of the original descriptions of some 
species which I have not seen, but which were taken by 
Messrs. Haliday and Walker, and forwarded to Dr. Forster 
at Aix, where they appeared in the *‘ Verhandlungen des 
naturhistorischen Vereins der preussischen Rheinlande ” 
for 1848. That author’s generic divisions are natural and 
easy of recognition, but his diagnoses of the various 
species are meagre in the extreme, ‘and, i in many instances, 
not sufficient to lead to their identity. The same remarks 
also apply to the descriptions of Meyer-Diir, published in 
the ‘‘Mittheilungen der schweizerischen entomologischen 
Gesellschaft,’ vol. iii, On the other hand, Dr. Flor, in his 
ote hynchoten Livlands,” vol. 11., and in a paper published 
at Moscow in 1861, under the title “ Zur Kenntniss der 
~Rhynchoten,” has more than compensated for the in- 
completeness of the others by the elaborate descriptions he 
there gives. He is pre-eminently ¢he man in this group, 
and his works have afforded me valuable assistance in 
determinating between species where I had any doubt. 
I have followed other authors by placing this group where 
it now stands, but I am not prepared to say that this is its 
true position, as it possesses some points in common with 
the true Cicadide.

The best methods I have found for the capture of these 
tiny creatures is by sweeping and by beating trees and 
bushes into a sw eeping-net or iny erted umbrella. I then 
put such species as | have found on a particular tree or 
bush or plant into a small glass tube, of which I carry a 
quantity ready labelled on which to write with a pencil ‘the 
name of such tree, bush or plant, so that when I come to 
set them I am at no loss to know where they came from ; 
and although three or four species may be found on one ieee 
yet I helieve this is accidental, or for the purpose which I 
shall mention presently, as each species, like the Aphide, 
seems to have its special food plant. Dr. Flor and 
M. Lethierry give many species as found by them upon firs, 
and these are ‘generally aken in early spring or very late 
in the season. May they not have assembled there for the 
purpose of hibernation, as these trees would afford them 
an excellent retreat? The two seasons would seem to 
point to this, 

In conclusion I may add that I shall be glad to examine 
and name to the best of my ability any species which may 
be sent to me for this purpose, as ‘T feel certain I have not

small, fascous. Legs yellow. Thighs: 3rd pair brown, 
apex pale. Claws dark brown. 

Abdomen above black. 

Length 1—1} line. 

A perfect anomaly, and when at rest more resembling 
a seed of some plant than an insect. 

Curtis has omitted the external basal cell of the elytra 
in his figure. I have old specimens taken by Mr. Wol- 
laston, and more recent ones captured by Dr. B. White. 

It occurs upon furze bushes ( Ulex Europeus), in June, 
but appears to be local.

flected; without the cyes almost pentagonal, with two 
fover manos in the centre ; width between the eyes more 
than twice the length, measiired down the centre, which

is divided by a channel, leaving a small notch in front; 
posterior margin angulate. QOcelli three, placed one in 
the frontal notch, and one adjoining each eye, almost on 
the posterior margin. Face lobate. Antenne 10-jointed ;

greatest breadth about equal to the width of the head 
without the eyes. Scutellum minute, apex rounded. Ely- 
tra almost uniform in width from in a line with the base 
of the cubitus ; coriéum, costal margin without a stigma; 
cubitus petiolate.

Green, dusky yellow or red. Mesonotum posteriorly 
with five longitudinal, brown or black streaks. Elytra 
transparent, with a Bice or brown longitudinal streak 
between the radius and cubitus, and three others at the 
margin alternating with the nerves.

of each dark brown or black. Ocelli bright red. Face 
variable in colour; lobes clothed with fine, pale hairs ; 
apex of each lobe with a long, fine, pale hair. Antenne 
dark brown or black, 2—é yellow, apex of 3—5 narrowly 
brown.

red ; foveze on the former dark brown, and five longitudinal 
streaks on the posterior portion of the latter dark brown 
or black. Scutellum generally yellow. £lytra transpa- 
rent; corium, nerves frequently pale, except the radius 
and the bifurcations of the cubitus; between the radius 
and the cubitus a broad brown or black streak extending

fuscous-black or brown margin. Frequently these charac- 
ters are more or less indistinct. Legs generally yellowish. 
Thighs more or less dark brown. 

Abdomen black, posterior margin of the segments nar- 
rowly yellowish or orange ; genital processes yellow, apex 
black. 

Length 13 line. 

I have restored Curtis’s name for this insect as it is 
some years older than that of Hartig. 

A very common species on furze bushes from May to 
August. 


Genus PsyLua. 


Head broader than long. Crown considerably deflected ; 
without the eyes broader than long; divided down the 
centre by a channel, and with a fovea on each side; the 
space between the fovex and the inner margin of the eyes 
much elevated or callus-formed; posterior margin more or 
less concave. Ocelli three, placed one in the frontal 
notch and one near each eye, adjoining the posterior 
margin on the summit of the elevated portion. Lace 
lobate; lobes variform. Antenne 10-jointed; two basal 
joints short, stout, somewhat obconic; 3—10 filiform ; 3rd. 
longest, 9—10 together about equal to the 8th; 10th with 
two. projecting fine hairs of unequal length. yes large, 
placed on the side of the head; viewed from above the 
outer margin very convex, inner margin slightly convex 
and lying at an angle to the central channel. 

Thorax : pronotum narrow, collar-shaped, with two 
fovez near the lateral margins, which last are incrassated ; 
posterior margin concave; mesonotum, anterior portion 
more or less obtuse, shuttle-shaped; base generally denti- 
form at its extremities; posterior portion across the middle 
as broad as or broader than the head and eyes together.

parent, rounded at the apex; costal margin at the base 
very convex, from thence straight or slightly convex, 
with a stigma sometimes almost obsolete. Cubitus pe- 
tiolate. 

Differs from the genus Arytena by having a smaller and 
more deflected crown, the two basal ocelli placed on a 

callus-formed elevation, the eyes lying at an angle to the 

central channel, and more “particularly by its greater 
breadth of mesonotum, in which respect it approaches the 
genus T'rioza.

This insect belongs to the same section as P. Fdrster?, 
Buxi, §c., owing to the shortness of the frontal lobes, and 
the almost total absence of a costal stigma; but from its 
smaller and more delicate appearance, independent of the 
form of the genitalia, it is easily distinguished. 

Apparently not uncommon in May and June on 
broom (Spartium scoparium). It is in the collections of 
Mr. Douglas, Dr. Power, and my own.

Flor, Rhyn. Livl. ii. 474, 12; Leth. Hém. Nord, 
ed. 11. 91, 14. 

Green or pale yellow, or yellow and green irregularly 
intermixed. Face: lobes somewhat elongate, stoutish at 
the base, and narrowing gradually to the slightly stumpy 
apex; length about equal to the crown down the centre. 
Pro- and meso-notum yellow, or intermixed with green. 
Elytra clear, transparent, glassy ; costal stigma distinct, 
whitish. 

Head: crown pale green or yellow, posterior margin 
gently concave. Face: lobes generally pale green, some- 
what elongate, proportionately stout at the base, and 
tapering gradually to the slightly stumpy apex, where they 
somewhat diverge ; length about equal to the crown down 
the centre. Antenne yellow, reaching almost to the base 
of the stigma; two last joimts always, and sometimes the 
apex of the 7th and 8th, black; 4th about three-fourths 
the length of the 3rd. 

Thorax : pro- and meso-notum yellow, or the latter with 
the anterior portion more or less green, and the posterior 
portion with a broad green space down the centre. 
Elytra clear, transparent, glassy; nerves fine, pale yellow; 
costal stigma distinct, whitish. Legs pale green or 
yellowish-green ; claws frequently dark brown or black. 

Abdomen greenish or yellowish. 

Length 14 line. 

A very delicate species, and somewhat resembling pale 
specimens of P. salicicola, to which it is related, but the 
different form of the face-lobes, colouring of the antennze, 
and want of the dark streak at the apex of the clavus, will 
at once separate them. 

Very common in May and June on hawthorn ( Crategus 
oxyacantha).

nating about in a line with the apex of the upper arm of 
the cubitus. 

Head: crown, posterior margin slightly concave. Face:

brown-red, sometimes the latter, with very indistinct 
indications of pale longitudinal lines. Elytra transparent, 
with a very faint testaceous tinge; nerves pale, varying 
slightly in depth of colour, according to that of the imdi- 
vidual; costal stigma widish at the base, and terminating 
about in a line with the apex of the upper arm of the 
cubitus. Legs yellow; in dark coloured examples some- 
times the thighs brownish ; t/b/@, apex and tars? brown. 

Abdomen above green or red, or brown-red; in the 
latter case generally the posterior margins of the segments 
pale, sometimes the entire abdomen black. 

Length 13 line. 

The var. rubida, Meyer-Diir, somewhat resembles 
P. salicicola, but it is smaller in size than the last- 
named, which has, in addition to the differences in the 
antenne and frontal lobes, a short dark streak at the apex 
of the clavus. 

Not uncommon from June to the end of August on 
various trees; amongst others I have taken it on birch 
and whitethorn.

the cubitus; radius concave in the middle, at which point 
it is slightly nearest to the stigma. Legs green. Claws 
brownish. 

Abdomen bright green. 

Length 14 line. 

This species belongs to the same group as P. mali and 
P. fraxinicola. It is larger than the first of these species, 
and about the size of the latter, and may at once be dis- 
tinguished from either by its bright green colour. A few 
specimens have been taken by Mr. Douglas on the common 
buckthorn (Rhamnus catharticus) or apple (he is not 
certain which), at Lee, in September; probably a form of 
P. mali.

Green or yellowish. Face: lobes shorter than the crown 
down the centre, exterior margin sloping rapidly to the 
stumpy apex. Antenne yellow, 3—8 joints at the apex 
narrowly dark brown, 9—10 dark brown. /ytra clear,

4th to the apex dusky; 4th and 5th together a little longer 
than the 3rd. 


British species of Psyllide. 545 


Thorax: pro- and meso-notum green or yellow, without 
paler longitudinal lines. £/ytra clear, transparent; apex 
almost imperceptibly fuscous; nerves from the base to the 
apex of the petiole yellow, from thence to the apex brownish- 
yellow; petiole of the cubitus and the lower arm subequal or 
nearly so. Costal stigma sometimes greenish, long, wide 
at the base, diminishing gradually to the apex. Legs 
yellow. Claws frequently brown. 

Abdomen entirely green or yellow. 

Length 13 line. 

A good character for the identification of this from other 
green species, as pointed out by Forster, is the shortness 
of the lower arm of the cubitus, which is only a little longer 
than the petiole. I have met with this species in the Isle 
of Wight in July, and in this neighbourhood, on ash trees 
(Fraxinus excelsior), in August and September, but not 
commonly. M. Lethierry says he finds it on elm. Dr. 
Power has taken it at Balmuto (Fifeshire).

in a short black streak, from thence to round the apex 
yellowish-white; nerve adjoining the apex of the clavus 
margined with brown on both sides; apex of the other 
nerves and an elongate spot in the spaces enclosed by them 
on the marginal nerve pitchy brown. Wings clear, trans- 
parent; costal margin dark fuscous. Legs reddish or

darker at the apex. Tarsi pale red. Claws brown. 

Abdomen above black; posterior margin of the seg- 
ments narrowly and sides broadly bright red. 

Length 14 line. 

The only species with which the above can be confounded 
is P. costatopunctata, which it resembles very much in 
the markings along the dorsal margin of the elytra. The 
last-named, however, is narrower, paler and has different 
formed face-lobes. Dr. Puton, in the Ann. Soc. Fr. for 
1871, p. 437, refers P. pyrisuga, Forst. to this species as 
being only a variety. This appears to me to be a decided 
mistake, as FOrster does not make mention in his descrip- 
tion of any spots on the dorsal margin of that species ; he 
simply says: “ Die Fliigel ziemlich wasserhell, mit réth- 
lichem Stigma und ahnlich gefiirbten Adern,” and speci- 
mens I have from Meyer-Diir fully bear this out. 

It would appear to be rare with us, as I have only seen 
a single example taken by Dr. Power at Cowfold (Sussex ) 
in May, another by Mr. B. Cooke, and two others by Mr. 
Douglas, beginning of November, on beech (Fagus syl- 
vatica).

Abdomen above in the ¢ red, down the centre broadly 
dark brown, sides broadly pale yellowish-white.

I met with two ? examples, in July and September, 
1862, which I suppose must have been captured by 
sweeping. Dr. Power has also taken a single specimen at 
Mickleham in October. Forster records having received 
it from the late Mr. Walker, and there is a specimen in the 
British Museum confirming this statement.

two anterior sides slightly convex. Face: lobes long, 
stout, conic, scarcely diverging at the apex. Antenne 
short, 10-jointed ; 1—2 joints short, stout ; remainder 
filiform, very fine ; 3—4 almost of equal length. Ocelli 
three, placed as in the other genera. 

Thoraz : pronotum narrow, deflected, with a fovea on

Length 1} line. 

This genus seems to unite Psylla with Trioza, but 
differs from both in the shortness and fineness of the 
antennee and the length of the face-lobes. Like Psylla it 
has a costal stigma, but the elytra are shaped like those of 
Trioza, from which genus it also differs in having the 
cubitus petiolate and the nervelets replaced by small 
granules on the dorsal margin. Frster says there are 
only three, but my specimens distinctly have four. 
Baron de Fonscolombe, who gave to Forster the insects 
from which his description is made, says he believes he 
obtaimed them from box (Buxus sempervirens), and also 
from other plants near Aix. Fdrster throws doubt upon 
the box theory, and perhaps correctly ; but if the insect 
was found at Aix, I see no reason against its occurrence 
here. 

The specimens which I possess were kindly presented 
to me by M. Lethierry, and are from St. Girons (Ariége), 
a department of France bordering on the Pyrenees. 


Genus Trioza, Forst. 


Head broader than long. Crown considerably deflected, 
divided down the centre by a channel and with a fovea on 
each side between the eyes; the space between the former 
and the latter slightly raised ; anterior margin more or 
less M-shaped; posterior margin more or less concave. 
Ocelli placed as in Psylla. Face lobate; lobes mode- 
rately long, generally triangular in outline, acute at the 
apex where the divergence is great. Antenne 10-jointed, 
formed as in Psylla, but shorter. 

Thorax: pronotum very narrow, collar-shaped, de- 
flected ; sides with a depression causing the lateral margins 
to become more or less lobate. Mesonotum and seutellum 
as in Psylla. Elytra generally transparent, lanceolate, 
more or less acute at the apex; costal margin convex, 
without a stigma; spaces enclosed by the nerves along 
the dorsal margin with three nervelets; upper branch of 
the upper arm of the cubitus terminating almost in the 
apex; cubitus not petiolate. 

The lanceolate form of the elytra with the three nerve-

the centre; base broad; apex stumpy; exterior margin 
convex, only slightly divergent at the apex. Antenne 
yellow ; Ist joint entirely, 2nd at the base dark brown ; 4th 
and 6th, apex narrowly black ; 9—10, or sometimes 8—10, 
black, 4th about three-fourths the length of the 3rd. 

Thorax: pronotum generally pale brown; mesonotum 
dark brown, clothed with short, semi-erect, pale hairs; 
anterior portion generally with a central longitudinal line, 
and the lateral margins pale; posterior portion with four 
pale longitudinal lines, placed one on each side of the 
centre, somewhat broad, and one narrower, a little more 
remote. lytra brown, semi-transparent, wrinkled trans- 
versely, and thickly powdered with dark-brown atoms; 
across the middle a more or less interrupted irregular 
white band, very broad on the costal margin, sometimes 
almost obsolete between the radius and cubitus, but always 
distinct between the nerves adjoining the apex of the 
clavus, sometimes the entire elytra are brown; costal 
margin very convex from the base to almost the apex of 
the radius, where it is suddenly cut off obliquely to the 
acute apex, before which is a somewhat triangular white 
patch. Legs yellow. Thighs generally dark brown at 
the base. Yarsi: 2nd joint sometimes at the apex red. 
Claws brown. 

Abdomen above black; posterior margin of the seg- 
ments very narrowly and sides red. 

Length 13—2 lines. 

The colour and peculiar manner in which the costal 
margin is cut off towards the apex is sufficient to separate 
the above from all other species. 


British species of Psyllide. joa 


Taken by Mr. Douglas and myself somewhat abun- 
dantly on blackthorn (Prunus spinosus), on Mickleham 
Downs in August, and by Dr. Power on the spindle 
tree (Huonymus europeus), near Addington, in October. 
Dr. Flor has taken it on the common buckthorn (Rhamnus 
catharticus). 

In the collection of Mr. B. Cooke are two ? examples 
of a remarkable variety of this species, in which the elytra 
are entirely pale, almost white, with only a few fuscous 
atoms seattered across the middle of the disk, and for 
which I propose the name albipennis. ‘They were taken 
by him at the same time and place as the others. 


Species 2. Trioza urtice.

Fuscous-yellow, yellow, orange, red or black, with 
brown or black streaks on the mesonotum in the first and 
third forms. Face: lobes black ; base more or less broadly 
pale, longer than the crown down the centre. Elytra 
somewhat elongate, clear, transparent or sometimes very 
faintly testaceous; apex obtuse; nerves pale yellow; 
distance of the radius at its base from the costal nerve 
about equal to that from the cubitus. 

Head: crown yellow or dark brown; in the latter case 
generally with the anterior margin pale or fuscous-yellow ; 
posterior margin almost straight. Face: lobes black, 
base more or less broadly yellow, rarely entirely black, or 
sometimes yellow with the apex black, longer than the 
crown down the centre, acuminate, considerably divergent 
at the apex. Antenne black; 2—3 joints white, 4th 
brownish, base white; 4th barely half the length of the 
3rd. 

Thorax: pronotum fuscous-yellow or yellow; meso- 
notum fuscous-yellow, yellow, orange, red or black; in the 
last case with the sides broadly red; in the Ist and 8rd 
with four brown or black longitudinal streaks on the

posterior portion, placed one in a line with each extremity 
of the scutelliform process, and another generally broader 
than the last nearer the lateral margin. L/ytra some- 
what elongate, clear, transparent, or sometimes very 
faintly testaceous; apex obtuse or sometimes bluntly 
rounded; nerves pale yellow ; radius at the base about 
equidistant from the costal margin and the cubitus, its 
apical half slightly convex tow ards the anterior margin. 
Legs fuscous-yellow. Thighs yellow, with a broad black 
longitudinal line somewhat on the inside, near the upper 
margin, generally extending to the apex. Tbie: apex 
frequently brown. Tarsi and claws pitchy brown. 

Abdomen above brown or black, posterior margin of 
the segments narrowly greenish or yellowish-green ; be- 
neath generally green. 

Length 14—13 line. 

Var. bicolor, Meyer-Diir. Head and thorax deep 
yellow. Abdomen green; all the other characters as 
above. ‘Types in my possession. 

Allied to 7’. albiventris, from which it may be recog- 
nized by the difference in colour and divergence of the 
face-lobes, and more particularly by the radius, which is 
almost one-half further distant from the costal nerve. 

Perhaps the most common and variable species of the 
genus, and may be swept from nettles (Urtica dioica, §c.) 
from May to October. 


Species 3. Zrioza viridula. 

Chermes viridula, Zett. I. Li. 309, 7; Psylla simplex,

Pale green. £lytra clear, with a glassy or crystalline 
transparence. 

Head pale green. Face: lobes at the apex brown or 
black, shorter than the crown down the centre, moderately 
divergent; apex acuminate. Antenne whitish or yellowish- 
white : apex of the 8th joint and 9—10 entirely black; 
3rd twice as long as the 4th. 

Thorax pale green. lytra clear, with a glassy or

green or greenish-yellow. TYarsi: 2nd joint entirely, or 
apex only, and claws brown. 

Abdomen pale green. 

Length 1} line. 

The delicacy and transparency of this species will sepa- 
rate it from all others. 

Flor says that it is not uncommon with him from June 
to October, upon the spruce fir (Pinus abies). I have 
only met with two examples; one in the August of this 
year, amongst rubbish at the bottom of a hedge, and the 
other in September, 1869, in the Sallow Pit, Lee.

Black, shining. Face: lobes short, outline somewhat 
pyramidal. Antenne black; 2nd joint at the apex and 
3rd entirely white. Hlytra very pale brownish-testa- 
eeous, transparent; apex not acuminate. 

Head black, shining. Face: lobes not so long as the 
crown down the centre; base broad; outline somewhat 
pyramidal. Antenne black; 2nd joint at the apex and 
3rd entirely white; 4th not halfas long as the third. 

Thorax: pro- and meso-notum black, shining; the latter 
at the insertion of the elytra brownish-yellow. Elytra 
very pale, brownish-testaceous, transparent, a little more 
than twice as long as broad; apex not acuminate; dorsal 
margin and wings at the base with a small black dash. 
Legs black. Thighs: apex brownish-yellow. Tibie white, 
base entirely fuscous, apex slightly brownish. Tars?: 
2nd joint at the apex and claws fuscous. 

Abdomen black; base reddish ; posterior margin of the 
segments very narrowly red. 

Length 14 line nearly. 

After carefully reading and comparing the description 
of 7. galii and velutina, as set forth both by Forster and 
Flor, I have come to the conclusion that the differences 
are more imaginary than real, and I have therefore ranked 
them as one species only, until I have examined more 
specimens. 

Haliday had collected this species in Ireland, as men- 

002 


556 Mr. John sM:. Monograph of the 


tioned by Forster; and the only specimens of recent cap- 
ture I have seen are one taken by Dr. Power at Darenth, 
in June, another at Lee, in August, and a third by 
Mr. Douglas. According to Haliday, he found 7. gali 
on the yellow ladies’ bed-straw (Galium verum); and 
Lethierry says he takes 7. velutina very commonly upon 
the same plant in August and September. 


Species 5. Trioza acutipennis.

Black. Face: lobes black, somewhat broad at the 
base, not longer than the crown down the centre. An- 
tenne yellowish-white; 1—2 joints black, 4th, 6th and 
8th narrowly brown at the apex, 9—10 black. Elytra pale 
brownish-testaceous, transparent; apex acute; nerves pale. 

Head black, shining. Crown: posterior margin straight. 
Face: lobes black, somewhat brvad at the base, not longer 
than the crown down the centre; exterior and inner 
margins gradually sloping to the somewhat acute apex, 
where the divergence is less than the base of either of 
them. Antenne yellowish-white, 1—2 joints black, 4th, 
6th and 8th narrowly brown at the apex, 9—10 black ; 
4th about ? the length of the 3rd, apex slightly thicker 
than the base of the 5th. 

Thorax: pronotum black; lobate side margins yellow; 
mesonotum black; at the base of the elytra red. Elytra 
pale brownish-testaceous, transparent; apex acute; nerves 
pale; radius straight, or very slightly bent before the 
apex; pro-and meso-sternum black; metasternum generally 
red. Legs yellow or brownish-yellow. Thighs pitchy 
black; apex yellow or brownish-yellow. Tarsi: 2nd 
joint more or less dark brown. Claws dark brown. 

Abdomen above black; ¢ genital segments pale 
brownish-yellow. 

Length 13 line. 

I have hesitated to refer the 7. acutipennis, Forst., 
to this species, as the differences he points out in the 
antenne and elytra are so much at variance with that 
of Zetterstedt. There is no doubt, however, but that the 
T. Saundersi, Meyer-Diir, belongs here, as I possess the 
specimens which he sent to Mr. Saunders, with his own 
label attached. 


British species of Psyllide. 557 


I have only seen a few specimens, although on the 
Continent it is said to be common in damp places from 
May to October. 


Species 6. Zrioza hematodes. 


Trioza hematodes, Forst. Verh. Ver. Rheinl. v. 85, 13;

transparent; nerves pale brown; radius short, space 
enclosed between it and the costal nerve lanceolate. 

Head: crown orange reddish. Face: lobes brownish- 
yellow, as long as the crown down the centre; base 
moderate; inner margin diverging from about the middle 
to the somewhat acute apex. Antenne black; Ist and 
2nd joints brown, 3rd yellow, 4th not 4 the length of the 
3rd. 

Thorax: pronotum pale; mesonotum brown-red, pos- 
terior portion with four somewhat brownish-yellow longi- 
tudinal streaks; scutelliform appendage yellow, with a

basal cell; enclosed space lanceolate. Legs slightly dusky 
yellow. Thighs with a dark streak along the inside near 
to the upper margin. Tarsz: Ist joint dusky, 2nd and 
claws black. 

Abdomen above brown ; posterior margin of the segments 
narrowly paler; beneath yellowish, 4 genital segments 
and processes yellow, apex of the latter narrowly brown. 

Length 13 line. 

Somewhat resembling 7. Urtice in some points, but 
differing from that species in the shape of the elytra, the 
short, almost straight radius and enclosed lanceolate space, 
and as also frequently having a slight fuscous shade along 
the dorsal margin before the apex of the clavus. 

The insects ticketed 7. forcipata by Meyer-Diir, which 
are in my possession, belong to the above species. 

Taken both by Dr. Power and Mr. Douglas: by the 
latter at Addington, end of October, on fir, and by the 
former in February at Esher.

We have no other British species for which it is likely 
to be mistaken. 

I have only seen a single ¢ example taken by Dr. 
Power at Balmuto, F ifeshine. 


Species 8. Trioza albiventris. 

Trioza albiventris, Forst. Verh. Ver. Rheinl. v. 84, 8; 
Flor, Rhyn. Livl. 1. 503, 6. 

Reddish-yellow or yellow-reddish, with two generally 
N-shaped characters on the mesonotum. Face: lobes 
black, longer than the crown down the centre, slightly 
divergent at the apex. /ytra clear, transparent, apex

ters; scutelliform process usually yellowish, with a more 
or less distinct brown or reddish-brown spot in the middle. 
El, ytra clear, transparent, apex acute; dorsal margin for 
about 3 its lenoth from the base somewhat moder ately and 
regularly curved or slightly flattened in the middle, from

yellow; 2nd joint at the apex frequently brownish. 

Abdomen above black, beneath pale yellowish-green 
or green, becoming white or bone white after death. 

Leneth 13 line. 

This insect stands nearer to J’. urtice than any other 
of our at present known to me British species, but differs 
from it in the colouration of the antenne, in having entirely 
black face-lobes, a long and peculiarly-formed radius much 
nearer to the dorsal margin throughout its entire length 
than is usual, of itself an excellent distineuishing char acter, 
and the abdomen beneath white after death, apart from 
other differences in the genitalia. 

I have only seen a few examples taken by Mr. Douglas 
at Addington in October, both on fir and birch. 


Genus APHALARA. 


Head much broader than long. Crown considerably 
deflected, divided down the centre by a channel and with 
a deep fovea on each side; anterior margin more or less 
M-shaped; posterior margin more or less angulate. 
Ocelli minute, placed as in the other genera, the frontal 
one not perceptible from ey Face without lobes. 
Antenne 10-jomted, short; 9—10 slightly thickened; all 
the others as in Psylla. Ey oe placed on the side of the 
head; inner margin almost parallel with the central 
channel ; outer margin very convex.

as in Psylla and Trioza, Elytra semi-transparent, 
rounded at the apex; cubitus petiolate, the petiole about 
4 the leneth of the lower arm; stigma obsolete. 


Resembles Psylla through having a rounded apex to 
the elytra and the cubitus petiolate, and Trioza through 
its having no stigma; and it differs from both in the shape 
of the head and the two slightly thickened terminal joints 


of the antenne.

Head: crown in front on each side of the channel 
slightly produced into a lobe with rounded top. Antenne 
pale yellow or sometimes whitish; Ist joint entirely and 
base of the 2nd black; 9—10 black. 

Thorax: pronotum pale; mesonotum greyish-yellow

sprinkled with fuscous or fuscous-black spots, which are 
more or less confluent ; before the apex a broad transverse 
fuscous-black band, generally more or less interrupted and 
spotted with the ground colour; dorsal margin with three 
fuscous or fuscous-black patches, placed, one a short dis- 
tance from the base, one a short distance from the apex of 
the clavus, and the 3rd margining the nerve adjoining the 
latter; nerves white or yellow. Legs yellow. Thighs in 
the middle broadly dark brown or black. Claws dark 

rown,

Abdomen black; sides and posterior margin of the seg- 
ments narrowly yellow; genital segments of both sexes 
yellow. Length 1 line. 

The broad appearance of this species, its white elytra, 
with the dark atoms and band before the apex, render it 
unmistakeable. 

Flor gives its size as greater than A. polygoni, but this 
is evidently an error. Dr. Power has taken it somewhat 
commonly at Weybridge from June to October, and I have 
an old example from Mr. T. Wilkinson, taken near Scar- 
borough.

apex generally somewhat fuscous; nerves pale or dark 
brown in certain positions, appearing as though margined 
with yellowish; dorsal margin, before the apex of the 
clavus, with a short black streak, and the adjoming nerve 
margined on both sides with black ; sometimes these last cha- 
racters are obsolete; clavus, apex frequently white. Legs 
pale brownish-yellow or yellow. Thighs on the inside, near 
the upper margin, generally with a brownish or blackish 
longitudinal streak. Tarsi: 2nd joint at the apex fus- 
cous. Claws brown. 


562 Mr. John Cris Monograph of the 


Abdomen dark brown or black; posterior margin of the 
segments narrowly yellow. 

Length 1—1} line. 

The black streak on the clavus will serve to distinguish 
this species from either of the other two. 

Dr. Power has taken it somewhat commonly on bireh, 
at Birch Wood, in May and June; Mr. Douglas, two or 
three examples, on fir, in October; and I have also one 
from Esher. Messrs. Walker and Haliday also met with 
it, the latter on the sorrel (Rumeax acetosella). It occurs 
from May to the end of October. 


Species 3. Aphalara radiata. 

Yellow or yellowish-green, with darker longitudinal 
streaks on the mesonotum. Antenne yellowish; Ist and 
2nd joints, except the apex of the latter, dark brown ; 9—10 
black. Llytra white, almost transparent, about two and a 
half times as long as broad; nerves yellowish or brownish- 
yellow ; internal basal cell with a fuscous-brown spot in 
the middle; the four branches of the arms of the cubitus 
and base and apex of the radius margined with fuscous- 
brown. 

Head: crown yellowish or yellowish-green; posterior 
margin slightly concave. Antenne yellowish; Ist and 
2nd joints dark brown, apex of the latter pale; 9—10 
black. 

Thorax: pronotum pale; mesonotum yellow or yellow- 
ish-green ; posterior portion with two broad, longitudinal 
dark-brown streaks on either side. Elytra white, almost 
transparent, about two and a half times as long as broad ; 
nerves yellowish or brownish-yellow; internal basal cell 
with a fuscous-brown spot in the middle; base and apex 
of the radius with a large fuscous-brown spot, the latter 
divided by a white streak next the costal margin; the 
four branches of the arms of the cubitus margined with 
fuscous-brown, widest at the marginal nerve, and joined 
internally by an irregular transverse fuscous-brown band, 
thereby giving a somewhat radiated character to the mark- 
ings; base of the cell between the arms of the cubitus with 
a fuscous-brown spot. Legs yellow. Claws brown. 

Abdomen dark brown or blackish; posterior margin of 
the segments narrowly yellow; ¢ genital processes yellow; 
apex black. 

Length 1—14 line. 

Very similar to A. nervosa, Forst., but distinguishable 


British species of Psyltide. 563 


from that species by the spot in the internal basal cell, the 
irregular transverse band connecting the fuscous-brown 
_ margins of the branches of the cubitus, and the spot at the 
base of the cell of the latter. . 

As regards the colouring of the pro- and meso-notum, 
the description may be found hereafter to be defective, 
because the specimens from which the foregoing has been 
drawn up are very old, and have been submerged along 
with the other valuables of the Rev. T. A. Marshall. 
There are four or five specimens in his collection taken 
at Cheltenham.

Head much broader than long. Crown deflected, with 
a shallow fovea on each side: central channel obsolete ; 
anterior margin convex ; posterior margin faintly concave. 
Ocelli as in Aphalara. Face without lobes. Antenne 
10-jointed, very short; 9—10 slightly thickened, 3rd 
elongate, 4—10 about equal i in length. yes placed on 
the side of the head ; outer margin convex. 

Thorax: pronotum narrow, somewhat deflected or 
horizontal; lateral margins about in a line with the outer 
margin of the eyes. /lytra not transparent, somewhat 
lanceolate; apex rounded; costal margin more convex 
than the dorsal one ; stigma distinct. 

In this and the ‘preceding ¢ genus the crown and face 
appear as continuous, and not separated as in Psylla and 
Trioza. 

Differs from Aphalara in the shape of the head and the 
elytra, and moreover possesses a stigma. 

The species of this genus are minute.

XVII. Note Dipterologice. No. 4.—Monograph of the 
genus Systropus, with notes on the economy of a 
new species of that genus. By J.O. WxEstwoop, 
M.A., F.L.S., Pres. Ent. Soc., &c. 


[Read 6th September, 1876.] 


In a collection of insects sent from Natal by Herr 
Gueinzius were several specimens of a new species of 
the remarkable Dipterous genus Systropus, together with 
several cocoons and their contents found upon a tree of 
the genus Mimosa, from one of which one of the Systropi 
had been bred. ‘The perfect insect itself is described 
below, under the name of S. crudelis. 

The cocoons are of an oval form, except that on one 
side they are flattened, showing marks of having on that 
side been attached to the bark of a branch or stem of the 
tree. At one end is a circular piece which is easily dis- 
engaged, the insect making its escape through the orifice 
formed by its removal. This cocoon is 7 lines long. The 
outer surface is quite smooth but not shining; the imner 
surface is also smooth and glossy, having its upper end of 
a darker colour than the remainder of the interior. In the 
absence of direct information we can only conjecture that 
the cocoon is that of a species of Egger moth (as certain 
British species are termed from the egg-like cocoon formed 
by their caterpillars), whilst the thick, parchment-like 
covering and shape of the cocoon agrees with those of the 
stinging larve of the genera Limacodes or Doratifera. 

Within each of these cocoons was found the pupa 
represented, magnified in the accompanying figures 6, 7 
and 8, of a short and thickened form, and quite unlike the 
parasitical pupee of Anthrax or Bombylius. The head- 
piece is armed with a strong, conical, frontal projection, 
by means of which the pupa is doubtless enabled to push 
off the operculum at the end of the cocoon. The head on 
the underside is furnished with a long appendage, extend- 
ing along the breast as far as the first ventral segment; its 
basal half is grooved down the centre as though it consisted 
of two halves; these are probably the antennze cases: the 
remainder of the appendage seems jointed in the middle. 


TRANS. ENT. SOC. 1876.—PART IV. (DEC.) PP 2 


- 
572 Prof. J. O. Westwood’s Monograph of 


This is evidently the sheath of the proboscis. The cases 
of the two fore legs are very short and bent back at the 
extremity of the femora, lying close upon the breast, whilst 
the cases of the two middle Tegs are more elongated, also 
Resting upon the breast and extending as far as the wing 
covers; which latter cover the cases of the hind legs, except 
the extremity of the tibize and the five-jointed tarsi. The 
abdomen is very robust and convex, each segment having 
a strong, short, curved bristle at each side, whilst the dor sal 
surface of each of the principal segments is furnished with 
a transverse row of very short, fine spines, which doubtless 
assist, with the lateral spines, in enabling the insect to push 
itself forward through the front orifice of the cocoon when 
the cap is removed. 

No one looking at this pupa would have supposed that 
it could have produced such an elongated, slender imago 
as the Systropus; but, fortunately, in one of the specimens 
the perfect insect had been secured in the act of making 
its escape from the pupa case, as represented in figure 9. 
Moreover, there can be no doubt from the necromorphous 
character of the pupe (the limbs lymg free, not soldered 
down as in the pupa of Lepidopterous insects), that the 
pupa is really that of a Dipterous insect and not of a 
Lepidopterous insect, within which the parasitic Dipteron 
had been reared. Although searched for with much care 
I did not succeed in finding, lying within the cocoon, any 
portion of the skin of the larva by which it had been 
formed, and suppose, therefore, that the parasite had en- 
tirely devoured it. Hence arises the question as to the 
precise nature of the parasitism of the Systropus. Was 
its larva an internal parasite, like the larva of the Za- 
chine ? or was it external, like the larva of Scolia, as 
described by Passermi? The latter seems to imply diffi- 
culties in the formation of a compact, oval cocoon, like 
that before us, by a caterpillar infested by an external 
parasite, unless we suppose that it was not until the cocoon 
had been formed, that the egg of the parasite, which had 
been attached to the outer surface of the caterpillar, had 
hatched, so as to enable the parasitic larva to feed without 
hindrance upon its prey within the closed cell of the cocoon. 
Further observations are therefore needed to determine this 
curious question. 

The specimen of the imago making its escape from the 
pupa skin, as shown in fig. 9, exhibited the different parts 
of the mouth in a condition very different from their ap- 


the genus Systropus. 573 


pearance when fully developed; instead of forming an 
apparently solid, single, porrected proboscis with the end 
divided into two recurved, slender lobes, the mouth pre- 
sented four delicate, straight lancets, represented in fig. 
10; one, the longest (fig. 10a), representing the labium; 
another, about two-thirds of the length of the former, 
which I regard as the tongue (fig. 100), two still shorter 
pieces which seem to represent the maxille (fig. 10ce); 
and at the base are two short, thicker pieces which I 
regard as the palpi (fig. 10dd); the upper lip (labrum ) 
would thus be unrepresented. 

It is interesting to find that the species of this anoma- 
lous genus are not confined to a narrow geographical range, 
but are very widely distributed; being natives of Africa, 
India, the Malayan Archipelago and South America. 

Two additional species of the genus have, I believe, 
been described by Signor Costa; but I have not been able 
to meet with the memoir in which his descriptions are 


published.

XIX, Descriptions of new species of Cryptoceride, belong- 
ing to the genera Cryptocerus, Meranoplus, and 
Cataulacus. By FREDERICK SMITH. 


[Read 4th October, 1876. ] 


HAvinG published three papers on this remarkable group 
of insects in the Transactions of the Society, I offer a 
fourth, in which twelve new species are described, of one 
of which I fortunately have obtained all the sexes, figures 
of which are given in the plate that illustrates the paper. 

In previous publications I have altogether described 
thirty-six species, those described in the present paper 
making the total number forty-eight. 

In a former paper I gave some account of the habits of 
these insects. For that information I was partly indebted — 
to the account published by Professor Lund, who describes 
the manner in which they capture their prey; this, he tells 
us, is similar to that of Hunting Spiders,—-by springing 
upon it. For the more interesting details, however, I was 
indebted to Mr. H. W. Bates, who, when resident in 
Brazil, observed these insects with great attention. He 
informed me that Cryptocerus constructed its burrows in 
decaying trees, its colonies not being numerous; consisting, 
in the nests examined, of about a dozen females, a few 
males, and the workers, numbering about the same as the 
females. 

Of the habits of the genera Meranoplus and Cataulacus 
no information had at that time been obtained. I have 
now the satisfaction of giving some account of the habit 
of a species of Meranoplus, M. intrudens, observed by 
Mr. John Monkhouse Hutchinson, resident in the Weenen 
district of Natal, South Africa. This species makes use 
of the thorns of a species of acacia, in which it constructs 
its formicarium; the thorns are from four to five inches 
in length, and, at the distance of about half an inch from 
the pointed end, a small round hole is made by the ants, 
which serves as ingress and egress to and from the nest. 
The thorns contain a kind of spongy pith, in which the 
channels and chambers of the nest are constructed. A 
remarkable fact in connexion with this insect is, that

when the thorns, forwarded in a letter, were received by 
Mr. Hutchinson’s mother, some of the ants were still alive 
and active, after having been at least six weeks on their 
journey ; so that, calculating from the time the thorns 
were collected in the Weenen district of Natal, at a spot 
one hundred and twenty miles from the coast, in all pro- 
bability the ants had been two months in reaching their 
destination, thus showing a wonderful tenacity of life in 
these insects. 

Subsequent to the reception of the first parcel of thorns 
a second supply has been received, in which it was found 
that many of the ants were still alive. Two of these 
thorns were sent to me, when, on cutting one open, I had 
the pleasure of finding the three sexes. Figures of each 
are given in the plate that illustrates this paper. 

One circumstance that I observed may possibly, to some 
extent, account for the fact of some of the ants being alive 
when they reached England. I noticed that the abdomen 
of several specimens was mutilated, a hole being observable 
on the upper surface of them. This gave rise to the 
suggestion in my mind of the possibility of the ants having 
fed upon each other. This is, however, a matter of entire 
uncertainty; but that they could easily gnaw holes through 
the integument of the abdomen is proved by the fact of 
their perforating the thorns, which are of a much harder 
consistency. 

Among the thorns sent, one or more were tenanted by a 
distinct species of ant, Psexdomyrma natalensis. These 
also were alive when received, the majority being females. 

Previous to finding the sexes of Meranoplus intrudens 
in the acacia thorn, I was unacquainted with the male of 
any species of that genus; it was, therefore, very gratifying 
to find that in this genus of Cryptoceride the male sex does 
not differ in form so entirely from the others as it is found 
to do in the genus Cryptocerus ; on the contrary, it greatly 
resembles the worker: it has however ocelli, which the 
worker has not. The female is distinguished by an 
elongated abdomen, a more ovate form of thorax, and 
having, like the male, both wings and ocelli. 

An interesting circumstance connected with the opening 
of the acacia spine that contained the three sexes of 
Meranoplus, was that of my finding with them a small 
bee belonging to the exotic genus Adlodape. This genus 
of bees is closely allied to that of Ceratina, the habit of the 
latter being to perforate the pith of dead bramble stems. 


new species of Cryptoceride. 605 


It may, therefore, be reasonably inferred that the habit of 
Allodape is similar, and that these bees perforate the 
acacia thorns and use them as their nidus in the same 
manner as Ceratina uses the bramble stems. The bee 
that was found might possibly have entered the thorn, 
tenanted by the ant, mistaking it for that which contained 
her own nest.

In the British Museum, from the collection of Mr. 
H. W. Bates. , 

The large worker of this species was described and 
figured in the second volume of the Transactions of this 
Society, Pl. XX. fig. 2. Mr. Bates subsequently sent 
specimens of both the sized workers, obtained from the 
nest; the small worker has a differently shaped head to 
the larger worker; the head is nearly flat above, slightly 
convex, punctured, with the margins pale reddish-brown, 
widest in the middle. The thorax is differently shaped 
anteriorly, not being obliquely inclined to the head; the 
abdomen and nodes of the peduncle are the same in form 
as in the larger worker. The male and the large and 
small worker are figured in the Catalogue of Formicidae, 
published by the trustees of the British Museum, Part VI.

Somewhat shining, deeply punctured, and covered with 
exceedingly short hairs. Head and thorax black; mouth 
and the sides of the thorax pale whitish. Scutellum black, 
with its apex, in pale specimens, sometimes pale. Elytra 
very variable 1 in colour, seldom with the membrane fully 
developed; in developed specimens the elytra are black, 
with the apex of the cuneus, a large triangular patch on 
the lateral margin at the base, and a amalter one at the 
apex, pale whitish ; the apex itself black; membrane 
milky white, extending considerably beyond the apex of 
the body, veins brown; in undeveloped specimens the 
elytra vary from being black, with the lateral margins at 
the base and apex pale, to being entirely pale ; between 
these extreme forms constant varieties occur. Legs pale; 
two lines on each thigh, and the extreme apices of the 
tibie and tarsi, black. Antennz pale, rather more dusky 
towards the apex.

Not rare by the sea coast, on marshy ground. 

The upright pubescence of the head, thorax and scu- 
tellum is the distinguishing feature of this species. 


7. orthochila, Fieb. (PI. XII. Fig. 3.)

the short, scarcely visible, black ones; thorax somewhat 
brassy, its sides straight; scutellum slightly swollen and

the antenne. 


9. marginalis, Fall. (Pl. XII. fig. 6.) 

Small and roundly oval ; dull black, with scattered, short, 
silvery-white hairs. Head, thorax and scutellum very 
finely rugose, the thorax scarcely impressed at the sides. 
Hlytra black; its sides, except at the extreme base and 
apex, pale; the colour spreading at the apex, and gene- 
rally also above the middle; membrane obscure. Thighs 
pitchy brown, the apices paler; tibize and tarsi testaceous,

A most distinct species. 


10. opacula, Zett. (Pl. XII. fig. 13.) 

Elongate oval, black, sides of the thorax widely im- 
pressed. Scutellum and clavus with golden hairs, the 
latter with an obscurely pale spot near the apex. Corium

species of this genus; rather densely covered with golden 
hairs. Head and thorax bronzy-black, with the sides 
straight or nearly so; discal impression very shallow but 
well defined. Elytra with the sides much rounded;

The short oval shape, straight-sided thorax and banded 


tibix, distinguish this species from all the others. 


12. arenicola, Scholz. (Pl. XII. fig. 5.) 

Deep black; thorax with the sides slightly rounded. 
Elytra with scattered golden depressed hairs, especially 
on the clavus; clavus with a small pale spot near the

Rare; Portsmouth, Bournemouth, Isle of Wight, &c. 

The almost white markings, the large transverse mar- 
ginal spot on the corium, and the dark tibize, separate this 
readily from S. saltatoria, &c.

and a few lateral spots, pale. Membrane pale, smoky ; 
sometimes darker at the base, with the cell-nerves black; 
cells with an oval dark spot in each. Legs pale, thighs

ton; also at Chobham, &c. 


14. saltatoria, Linn. (PI. XII. fig. 7.) 
= fucicola, Dougl. & Scott. 
= marginella, Dougl. & Scott. 

Var. = vestita, Dougl. & Scott. 

Exceedingly like the preceding, of which it may be but 
avariety. It differs in having the markings on the elytra 
more numerous, more decided, and without the tendency 
to spread observable in that species. The spots get paler, 
but they retain their form, and I have never seen any 
specimens with pale elytra. Although so closely allied to 
the above that I cannot describe the differences in words, 
yet there is a general look about saltatoria by which, 
I believe, anyone could distinguish it. 

Length 14—2 lines. 

Common in damp places. Var. vestita, Scotland. 

Var. vestita, Doug]. & Scott. Pubescence much denser, 
giving quite a golden aspect to the specimen. 

I have placed under the two preceding heads what have 
been considered by some authors as six distinct species; 
but, after a careful examination of a great number of spe- 
cimens of my own, as well as many kindly lent to me by 
Mr. Douglas and Dr. Power, I can come to no other 
conclusion. Even between the two species I have ad- 
mitted I can see no distinguishing structural characters, 
and the markings vary to such an extent that it is only on 
their general style that one can place any reliance. 


15. elegantula, Fall. (Pl. XII. fig. 14 (antenna).) 
= Flori, Dohrn, &c. 

Head, thorax and scutellum black, shining, covered 
with long, erect, black hairs; eyes very large and promi- 
nent; sides of the thorax converging rapidly i in straight 
lines untjl they almost reach the anterior margin, then 
subparallel; discal transverse impression very wide and 
deep; base sinuate. LElytra black, dull, covered with 
long, black, erect hairs, and a fine golden adpressed pubes- 
cence; the lateral margins, from just below the base,

widely ochreous, the colour spreading at the apex and just 
above the middle, along the nerve of the corium; close to 
the apex, where the pale colour spreads inwards, is a small, 
round, clear, whitish spot, and on the disk are often a few 
irregular, glaucous or milky spots. Membrane very small, 
ochreous, the nerves dark. Legs testaceous. Antenna 
black, apex of basal joint and sometimes a spot on the 
apical joint yellow. 

Length 13—14 line. 

Rare; banks of the Thames, near Hammersmith, &c. 


16. Cocksii, Curt. (Pl. XII. figs. 10 and 15 (antenna). ) 
= elegantula, Dougl. & Scott. 

So like the preceding that it is unnecessary to do more 
than point out its distinguishing characters. The an- 
tenn are considerably dilated at the apex, and the second 
joint is yellow, except at its extreme base. These cha- 
racters are so pronounced that the species may be at once 
separated from elegantula. 

Length 13—1# line. 

Not rare in damp places, Sphagnum, &c. 

This is evidently not Costa’s geminata, a very distinct 
species of which I have several from Dr. Ferrari of Italy, 
and which has been also named venustula by Mr. Scott, 
from a var. with the apical joint of the antennz spotted. 


17. cincta, H.-Schff. (Pl. XII. fig. 9.) 

Somewhat like the two preceding species, but very 
different on examination. The surface has not the erect 
black hairs of the others, and the thorax is less rapidly 
constricted in front; the elytra are more elongate and the 
sides less rounded; the membrane much larger, &c. 
(These latter characters, however, probably depend on 
development. Cincta appears always to be found fully 
developed, whereas elegantula and Cocksii are almost 
always not so. I have a single specimen of Cockszi from 
South Europe, with the full membrane, and in this case 
the shape of the elytra is very similar to that of eincta.) 
The pale colour at the margin of the corium is much 
narrower, and does not spread either in the middle or at 
the apex. The antennz are much thinner and black, the 
apex of the Ist joint only pale. 

Length 13 line.

Shining olive-brown. Head ochreous; thorax with 16 
or more paler, transverse lines; corium and clavus with 
a few long scattered hairs, very finely and closely mottled 
with paler markings; beneath and legs testaceous. Dis- 
tinguishable from the others of this section by its larger 
size, and the greater number of pale lines on the thorax. 

Length 6 lines. 

Common in ponds, &c. 


2. affinis, Leach. Fig. Fieb. Spec. Coris. pl. i. fig. 5

Like the above, but smaller, and the pale markings 
rather more conspicuous; the pale much shorter; the 
pale lines on the thorax fewer, &c. Claws of intermediate 
legs longer than the tarsi.

markings of the clavus. I have never seen the species. 


5. preusta, Fieb. Fig. Spec. Coris. pl. i. fig. 17. Var. 
socia, D. & S. 

Dull olive-brown, with paler markings. Thorax with 
9—10 rather irregular pale lines; clavus with pale trans- 
verse bars, the markings becoming irregular towards the 
apex; corium with irregular transverse wavy markings. 
Legs testaceous, spot on the hind tarsi large, quadrate or 
subtrapezoidal (var. socia). 

Length 3 lines. 

Not rare; Lee, Reigate, Scotland, &c. 


6. concinna, Fieb. Fig. Fieb. Spec. Coris. pl. ii. fig. 9 
(pale). 

Very like the above, but with the markings of the 
thorax rather more regular, and those of the clavus rather 
less regular. Dorsal line of the thorax indicated by a 
slight tubercle in front. The most conspicuous character 
is the small spot on the hind tarsus, which only just fills 
the inner apical angle of the 1st joint, and the inner basal 
angle of the 2nd. The pale also are much longer than 
in preusta. 

Length 3 lines. 

Lewisham, Lee and Esher. 


7. cognata, Dougl. & Scott. 

Very like the preceding, but differs from it in not 
having any indication of a tubercle on the anterior mar- 
gin of the thorax; it is also, if anything, rather smaller 
and of a yellower colour, and has the spots on the hind 
tarsi more pronounced and not extending on to the 2nd 
joint. The palz in the ¢ are also very different. 

Length 2$—=3 lines.

Gosforth. 


648 Mr. E. Saunders’ Synopsis of 


9. Wollastoni, Doug]. & Scott. ; 

Differs from all the preceding by its uniform dull 
colour and almost obsolete markings; the corium is uni- 
colorous, except at the base, where a few paler transverse 
markings are observable; the spots on the hind tarsi are 
also more elongate, and the entire insect is very slightly 
larger. 

Length 34 lines.

Posterior metatarsi not spotted with black at the apex. Corium 
not rastrate. 

10. hieroglyphica, Duf. Fig. Fieb. Spec. Coris. pl. i. 
fig. 20 (pala). 

Pale ochreous-white ; the thorax with 7—9 very fine 
black lines; dorsal line slightly raised in front. Elytra: 
clavus very irregularly barred transversely ; corium with 
smaller mottling than the clavus, the pale colour decidedly 
dominant. 

Length 23 lines. 

Not uncommon in ditches, &e. 


11. lugubris, Fieb. Fig. Spec. Coris. pl. i. fig. 10 (pala). 

Differs from the above in being darker, the dark Imes 
of the thorax being almost as wide as the pale ones, and 
the darker colour being dominant on the elytra. 

Length 2? lines. 

Not uncommon in ditches, &e. 


12. Stali, Fieb. 
Exceedingly like /ugubris, but rather darker, and with 
a decided tubercle indicating the dorsal line on the an-

Black, dull, very rastrate; thorax with 6 well-marked, 
pale lines; clavus transversely barred with pale lines, straight 
at the base and more or less irregular and wavy towards 
the apex ; corium with narrow, fine, wavy, transverse lines; 
beneath, head and legs pale. 

Length 33 lines.

British Hemiptera-Heteroptera. 649 


14. Sahlbergi, Fieb. Fig. Spec. Coris. pl. i. fig. 3. 

Very like the above, but at once distinguishable by the 
longer thorax, by the greater number of pale lines (8—9) 
on it, and the pale apex of the corium; it is also slightly 
larger. 

Length 33—4 lines. 

Common in ponds, &c. 


13. striata, Fieb. Fig. Spec. Coris. pl. ii. fig. 4 (pala). 

Differs from either of the above by its more shining and 
less rastrate surface. Thorax with 6—7 dark lines, about 
equal in width to the intervening pale ones. Clavus irre- 
gularly marked with pale transverse lines, the basal ones 
widening inwardly. Corium with transverse, interrupted, 
pale markings; beneath, head and legs pale. 

Length 34 lines. 

Common in ponds, &c. 


16. vernicosa, Walleng. = Douglasi, Fieb. 

Very like striata, but has the thorax more deeply ras- 
trate, and the transverse dark lines somewhat impressed ; 
the pale basal markings of the clavus also are not widened 
inwardly as in that species. 

Length 34 lines. 

Fens. 


17. Fallenii, Fieb. Fig. Spec. Coris. pl. il. fig. 12 
(palze). 

Distinguishable from either of the preceding by the 
greater number of transverse dark lines (8—9) on_ the 
thorax, by its more distinct and regular markings, and by 
the shape of the pale in the ¢, which are subtriangular; 
lateral angles of the thorax acute. 

Length 3} lines. 

Common in ditches, &c. 


18. distincta, Fieb. Fig. Spec. Coris. pl. u. fig. 13 
(pale). 

Exceedingly like Fallenii, but differing in the slightly 
longer thorax, the rather wider, black, transverse lines across 
it, the obtuse lateral angles, and the short pale of the ¢, 
which have the posterior margin regularly rounded. 

Length 34 lines.

650 Mr. KE. PP acrs Synopsis of 


SMALLER SPECIES. 


19. masta, Fieb. Fig. Spec. Coris. pl. 11. fig. 17. 

A short, obscurely-marked species, with a very short 
thorax and large head; at once distinguishable by the form 
of the intermediate legs, which have the tarsi only very 
slightly shorter than the tibiz, and the claws subequal to 
the tarsi. 

Length 2} lines. 

Common in ponds, &c. 


20. Fabricii, Fieb. Fig. Spec. Coris. pl. 1. fig. 16

= perpleza, D. & S. 
= borealis, D. & S. 
= Whitet, D. & S. 
= decora, D. & S. 
= dubia, D. & S. 

Moderately rastrate, more or less shining; brownish- 
black, with pale markings. 

A very variable species in colour; but I can detect no 
structural character to separate the varieties from each 
other. Ngrolineata is the palest var., borealis the darkest. 
This species is separable from its allies by the short, rather 
wide, smooth tubercle on the anterior margin of the 
thorax. 

Length 23 lines. 

Not rare; in ditches, &c. 

Mr. Douglas, in Ent. Mo. Mag. 1875, Nov., unites 
decora and perplexa with Whitet, and dubia with nigroli- 
neata. Dr. J. Sahlberg, in his ‘‘ Synopsis Amphibico- 
risarum,” &c., unites decora and dubia with Fabricii and 
ni igrolineata. I feel little doubt, however, that I am right 
in referring all these varieties to one species. 


21. limitata, Fieb. Fig. Spec. Coris. pl. ii. fig. 20. 

A pale species, with very distinct black markings; 
longer and narrower than the preceding; the markings on 
the corium interrupted near the inner apical angle by two 
black, longitudinal lines; intermediate claws very long, 
as long or longer than the tibiz. 

Length 23 lines.

Darker than Umitata, and at once distinguishable by 
the pale markings of the elytra being divided into four 
distinct series by reason of three dark, longitudinal lines; 
extreme apical margin of corium pale. 

Length 2$ lines. | 

Not rare; in ditches, &c. 


23. venusta, Doug]. & Scott. 

Very like the preceding, of which it may prove to be 
only a variety. Brown, with paler markings, very ras- 
trate. Thorax with 6—7 impressed black lines; corium 
with four longitudinal lines, the first placed at the inner 
apical angle; extreme apex pale, legs pale, intermediate 
claws about equal in length to the tibiz, much longer than 
the tarsi.

24, fossarum, Leach. Fig. Fieb. Spec. Coris. pl. ii. 
fig. 15. 
Var. prominula, Thoms. 

Rather longer and with clearer markings than mesta, 
from which the shape of the intermediate legs at once 
separates it; the thorax has six distinct, pale lines across 
it. The head, between the eyes, is produced and slightly 
rounded, the posterior margin deeply emarginate. 

Length 2} lines. 

Common in ponds, &c. 


25. Scotti, Fieb. 

Very like the above, but rather smaller; the head more 
depressed above, and somewhat angular in front, and very 
much excavated behind; the posterior angle of the eye 
almost touching the anterior angle of the thorax, which is 
traversed by only five pale lines.

This very distinct species cannot be confounded with 
any other here described; its large, rounded eyes and 
bulbous head, and long meade tarsi, which are as 
long as the ses distinguish it at once. The thorax is 
very rastrate, and has a short, distinctly raised, dorsal line 
in front, reaching to a little hebead the middle; the elytra 
are matiiee obscurely marked, and have Scattered! long,

Paper read, &c. 

Mr. M‘Lachlan directed attention to an article, by M. Flaminio Baudi, 
in the ‘ Petites Nouvelles Entomologiques,’ respecting the habits of Cychrus 
eylindricollis, which he had taken on Monte Codeno feeding on the body of 
a snail (Helix frigida), into the shell of which the beetle was enabled to 
thrust its head and long narrow prothorax. Some interesting remarks 
were made by Mr. Bates and others on the peculiar structure and habits of 
the insect, which appeared to have been found only on a very sterile portion 
of the plateau of the mountain, and in no other part. 

A valuable paper was communicated by Dr. D. Sharp, entitled “ Con- 
tributions to an Insect Fauna of the Amazon Valley—(Staphylinide).” Of 
this important group of Coleoptera 487 species were enumerated as inhabiting 
the valley, of which 463 were described as new—suggesting forcibly how 
little is really known of the Staphylinidz of Tropical America. Dr. Sharp 
also stated that he had devised a method of covering and hermetically 
sealing the type specimens, which, he believed, would accomplish their 
almost complete preservation, and that he hoped soon to be able to publish 
a description of the method. The author concluded with remarking on 
the great importance of certain sexual characters in distinguishing the 
species.

Election of Members. 


Dr. G. Kraatz, President of the Entomological Society of Berlin, and 
Mr. Clemens Miiller, also of Berlin, were balloted for and elected Foreign 
Members; and Mr. Oliver E. Janson, hitherto a Subscriber, was elected an 
Ordinary Member. 

Exhibitions, déc. 

Mr. Jenner Weir exhibited two grasshoppers in an undeveloped state, 
taken by himself in the Rhone Valley, in copuld—a peculiarity which was 
frequently noticed amongst the Hemiptera. He also exhibited a remarkable 
moth from Madagascar belonging to the family Uraniide, bearing a very 
striking resemblance to a Papilio, except that it had the antenne of a moth. 

Mr. Edmund Y. Western exhibited some Coleoptera, taken chiefly in 
Switzerland. : 

Mr. W. Arnold Lewis exhibited a specimen of Argynnis Dia taken in 
England by Mr. Wallace A. Smith, whom he presented to the Meeting. 
Mr. Smith stated, in answer to various enquiries by the President, that he 
captured the specimen himself in the year 1872, while sunning itself on 
some palings near his own house at Worcester Park, Surrey, and it was on 
an exceedingly hot day, though he did not remember the month. He had 
only commenced collecting insects in the preceding summer, and it was the 
first Fritillary he had ever had in his possession, and the specimen had 
never been out of his possession since. He was unable to identify the 
species at the time, and was not aware of the rarity of the insect until he 
showed it to Mr. Lewis. The specimen was handed to the Members and 
pronounced to be undoubtedly an Argynnis Dia. Mr. Lewis remarked that 
he had seen so many attacks in past publications on those who asserted 
that Dia was a British species, that he was very desirous that the testimony 
connected with the present capture should be recorded. 

The President noticed a paragraph in ‘ Newman’s Entomologist’ stating 
that the collection of butterflies and moths formed by the late Mr. Henry 
Doubleday was now being exhibited at the Bethnal Green Museum; and 
he hoped that special care would be taken of it, as it was by far the most 
valuable collection of British Lepidoptera in existence. 

Mr. Dunning exhibited a pair of Caradrina morpheus taken én copula in 
the Regent’s Park, the male being dead, and, although still attached to the 
female, several eggs were laid and larve hatched therefrom in the box in 
which they were placed. — 

Mr. Bates read a letter from Mr. Trovey Blackmore to Mr. M‘Lachlan, 
stating that he was much interested in observing a notice in the ‘ Pro- 
ceedings’ of this Society respecting the habits of Cychrus cylindricollis, 


e iv 


reported by M. Baudi to feed on snails. He had already called attention (in 
the ‘Entomologist’s Monthly Magazine,’ vol. xi., p. 214) to the fact that 
Carabus stenocephalus, Fgirm., fed on snails, which in Morocco were so 
very abundant as to form a marked feature in the landscape by covering 
the bushes so thickly as to resemble, at a distance, clusters of blossom. He 
had captured in all eighteen specimens of this scarce Carabus, and of these 
fifteen were obtained either feeding on snails or climbing up bushes of 
Retama, which were covered with snails, especially Helix planata. The 
Carabus having an unusually long head, and the prothorax being narrowed 
anteriorly, enabled it to thrust its head and prothorax a considerable distance 
within the shell in search of its food. It belonged to a group comprising 
several species found in North Africa, which much resembled Cychrus in 
appearance, and which possessed characters sufficiently marked to entitle 
them to form, if not a genus distinct from Carabus, at least a subgenus of 
Carabus. One of them (possibly a var. of C. stenocephalus) occurred in the 
more northern parts of the Atlantic coast of Morocco, and had been named 
by Fairmaire C. cychrocephalus ; and another species (C. Awmonti, Lucas), 
had been found at Oran and in the Angera Mountains near Ceuta, which 
had a far narrower prothorax; but as he had not met with it himself he was 
unacquainted with its habits. He believed that other Carabi might be 
found whose habits were similar to those of C. stenocephalus. 

Mr. Bates made some remarks on this as an instance of the modification 
of a form to adapt the insect to a difference of habit: it could not be con- 
sidered a case of affinity, Carabus and Cychrus being totally distinct genera, 
The President, however, considered that the form was simply adapted to 
the purpose for which the insect was created. 

The President drew attention to a subject now being much discussed in 
Germany and the United States of America, with reference to the spring 
and autumn broods of Lepidoptera, which proved to be modifications of the 
same species. He was much interested in the subject, and would be greatly 
obliged to any entomologist who would furnish him with observations and 
notes as to the different broods. 


, Papers read. 

The President read a paper entitled “A Dipterological Note from Pom- 
peli,” containing remarks on the habits of the genus Bombylius. Also 
descriptions of some new species of Tipulide in the British Museum, 
accompanied by drawings, showing them to be furnished with hind legs of 
unusual length. 

‘Mr. John Scott contributed a Monograph of the British species belonging 
to the Hemiptera-Homoptera (family Psyllid), together with a description 
of a genus which might be expected to occur in Britain.

Election of Members. 


The following gentlemen were balloted for and elected Ordinary Members 
of the Society :—Joseph William Douglas, Esq., of Lee, Kent: Edward C. 


vil 


Rye, Esq., of Parkfield, Putney; Charles Fenn, Esq., of Lee, Kent; George 
Lewis, Esq., of Queen’s Road, Putney; John Dunning Kay, Esq., of Leeds ; 
and William Charles Copperthwaite, Esq., of the Lodge, Malton. Also, 
Benjamin A. Bower, Esq., of Lee, Kent, was balloted for and elected a 
Subscriber. 

Exhibitions, &c. 

Mr. F. Bond exhibited a specimen of Xylina lambda, taken near Erith, 
in September last, by Mr. W. Marshall, being the fifth instance of its 
having been taken in Britain. Also Ebulea stachydalis, taken by himself 
at Kingsbury, Middlesex, in June, 1862. 

Mr. Champion exhibited a specimen of A%gialia rufa, Fab., taken by 
Mr. Sidebotham, of Bowdon, near Southport, and he brought specimens of 
Psammodius sulcicollis sent by Mr. Sidebotham for distribution amongst 
the Members. 

The President made some observations respecting the habits of the 
common gnat, in coutinuation of his remarks at the meeting of 4th 
November, 1872. [See ‘ Proceedings,’ 1872, p. xxxi.] Large numbers of 
females had again appeared in his house at Oxford, not a single male 
having been observed; and he believed that they had hybernated in the 
house, appearing during the first warm days of spring. He also remarked 
that Dr. Leconte’s valuable collection of Coleoptera had been presented to 
the University at Cambridge, Massachusetts. 

Sir Sidney 8S. Saunders exhibited two examples of Stylops Kirbii, taken 
on the wing by him at Hampstead, in the forenoon of the previous day. 
He had found eighteen males in all: one Andrena contained three 
undeveloped males. Mr. Knock followed up this exhibition by an 
account of his own captures of male Stylops at the same time. He 
captured eleven on the wing, and one Andrena was taken with four 
individuals. 

Mr. Eaton stated that he was preparing a Supplement (dealing with the 
limitation of the genera) to his ‘‘ Monograph on the Ephemeride ” (Trans. 
Ent. Soc., 1871). A considerable amount of new material had been most 
kindly submitted to him by Mr. Robert M‘Lachlan, of Lewisham, and 
M. Herman Albarda, of Leeuwarden, comprising specimens from almost all 
parts of the world. Amongst the most interesting were some specimens in 
fluid from South America, and a collection from Sumatra. From the 
Amazonian collection in spirits, it would appear that the deficiency in legs 
in Campsurus and some of its allies was due to their being shed with the 
pupa-skin when the insect obtained well-developed wings. In some forms 
all of the legs were then cast off by the female (this was apparently the case 
with Euthyplocia also); in others the anterior pair of legs was retained by 
the female, as it was seemingly by all males. The separation of the legs 
cast off takes place between the femur and the trochanter. The posterior 


- vill 

legs would be useless to them, as on attaining the complete winged stage of 
development they retain the subimaginal pellicle, and live but few hours in 
the air. From Lahat there were subimagines of a Cronicus, a genus known 
previously only from a fossil in amber from Prussia. , Several new forms, 
whose existence was expected from analogy, were in these collections. The 
whole family seems to consist of associated series of genera. In every series 
the forms differ from one another in the number of setee or wings; while in 
tarsi and neuration and eyes they are very much alike. Such are a form 
distinguishable from Lachlania by the female possessing three long sete 
instead of two only; another differing from Potamanthus (restricted) in 
the middle seta being extremely short and minute; and another which 
resembled Siphlurus, excepting in the possession of a long intermediate seta 
instead of a minute rudiment of one. ‘There were many new genera allied 
to the typical Leptophlebia, in addition to the series of species associated 
with it in the Monograph as sections, which will now be separated as genera 
from it. 

The President exhibited some drawings which he had prepared of insects 
belonging to the Dipterous genus Systropus, of which he intended shortly 
to publish remarks on their transformations. 

The Rey. R. P. Murray stated that he was preparing a resumé of all the 
species of Japanese butterflies hitherto noticed, and that he would be grateful 
to any entomologist who could assist him with the loan of specimens. 

Mr. Smith made some remarks on the distribution of some genera of 
Hymenopterous insects from New Zealand, a collection of which had 
been placed in his hands by Mr. C. M. Wakefield. He was followed by 
Mr. M‘Lachlan, who remarked on the gradual extinction of the endemic 
Fauna of New Zealand, although introduced forms throve there in a 
remarkable manner. 

Mr. M‘Lachlan exhibited a series of a remarkable Trichopterous insect 
received from its discoverer, Fraulein Marie vgn Chauvin, of Freiburg, in 
Breisgau, described by Stein as Anomalopteryx Chauviniana. In the male 
the anterior wings were lanceolate and the posterior much abbreviated, 
whereas those of the female were normal, excepting that the posterior wings 
were smaller than usual. He also exhibited apterous females of Acentropus 
niveus received from Mr. Ritsema, of Leyden: and a slide with a full-grown 
female of the root-form of Phylloxera vastatrix, recently obtained by him 
(with many others) from a vinery near London that was greatly infested 
with the insect.

Foreign Member. 

Exhibitions, &c. 

The Rev. J. Hellins sent for exhibition various British Lepidoptera 
recently submitted to M. Guenée for his opinion and determination. The 
collection included a dark variety of Acronycta myrice from Mr. Birchall ; 
certain Acidalize, sent by Mr. Hellins and Mr. G. F. Mathew, apparently 
to be referred to A. mancuniata; several extraordinary aberrations referred 
to Melanippe rivata, Oporabia, sp.?, Coremia ferrugata, &c., from Mr. Dale 
and Mr. Mathew; an example of Polia Chi, var. olivacea, from Major Hut- 
chinson ; several Eupithecie, from Dr. Buchanan White, including the var. 
oxydata of E. subfulvata; and an insect which Dr. White proposed to name 
septentrionata, not known to M. Guenée. The most important of all was a 
Noctua bearing some resemblance to Xanthia circellaris (ferruginea), not 
known to M. Guenée, taken at Queenstown, flying over bramble-blossoms, 
in July or August, 1872, by Mr. Mathew. Concerning this insect it was 

Cc 


ew x 


remarked that it had been shown to Dr. Staudinger (now in London) by 
M. Guenée, and it was also unknown to him as Kuropean. 

Mr. Distant exhibited a series of six examples of the butterfly Ithomia 
Tutia, Hewitson, from Costa Rica. These had been selected to show the 
very considerable variation in markings to which the species is evidently 
liable. 

Mr. Distant also communicated the following remarks on 


The Rhopalocera of Costa Rica. 


“In the ‘Proceedings of the Zoological Society’ for the year 1874, 
Messrs. Butler and Druce published a paper on the ‘ Butterflies of Costa 
Rica,’ from a collection brought to this country by Dr. Van Patten. 
Besides other Lepidoptera from Costa Rica, I have lately become possessed 
of the remainder of a collection made in the same locality by Mr. Gabb, and 
find the following species not included in the list of Messrs. Butler and 
Druce. That Catalogue contained the names of 434 species, and it is 
therefore very desirable in the interest of the study of geographical distri- 
bution that a list so large and useful should be made as complete as possible. 
I also find several distinct forms, of which I either possess or have seen 
both sexes and series from Costa Rica: these I have described. The forty 
species by which I have thus supplemented the Catalogue of Messrs. Butler 
and Druce should together give a moderately complete analysis of the 
butterfly fuuna of Costa Rica, though probably more species of the family 
Hesperide may yet have to be added. 

“ As the value of these faunistic catalogues is principally in the study of 
geographical distribution (a subject which I have for some time been 
investigating), and their completeness is an essential necessity, I should be 
glad to have this opportunity of asking entomologists who frame such lists 
not to only give the species contained in one collection, but to include every- 
thing previously recorded from the same locality. Specific differences 
usually considered slight become factors of exceeding interest when dealing 
with the problems of distribution and dispersion, and I feel confident it 
will be chiefly by the records of these modifications (when constant) that 
we shall ultimately arrive at a knowledge of the laws of geographical 
distribution. 

“J have strictly followed the arrangement of Messrs. Butler and Druce 
in their paper.

T?rUNA ALBESCENS, 2. sp. 


Front wings pale ochreous, transparent, with the following dark fuscous 
opaque markings :—A wide streak occupies one-half of the interno-median 
interspace. A somewhat broad band extends from costa through middle of 
cell, along first median nervule, to outer margin; a second band of about 
the same width commences on subcostal nervure and crosses end of cell 
along second median neryule to outer margin. ‘These two bands coalesce 
on the median neryure. A somewhat obscure and interrupted band crosses 
wing between apex and end of cell. ‘The costal and outer margins are of 
the same colour, broadest at the apex and least at the costa between the 
first and second bands. Inner margin rufous. Hind wings ochreous, trans- 
parent, a dark fuscous opaque costal margin extending along second subcostal 
nervule to outer margin, which is broadly of the same colour. Under sides 
as above; the dark fuscous is of a bright chocolate colour; a few white 
spots at apex of front wing, and a marginal row of same coloured spots to 
hind wings. Exp. 4 in. 2 lin. 

Dr. Staudinger has kindly examined this species, and says it is quite 
distinct from a similar form he has lately described from Pebas, and which 
was a true Hutresis.

Mr. Douglas exhibited specimens of the Corozo nut (Phytelephas macro- 
carpa), the vegetable ivory of commerce, of which the interiors were entirely 
eaten away by a species of Caryoborus (one of the Bruchides). A specimen 
of the beetle was shown with nuts, from the London Docks, which had 
been recently imported from Guyaquil. 

The Secretary read a letter he had received from the Foreign Oftice 
Department, enclosing a despatch from Her Majesty’s Minister at Madrid 
relative to the steps taken to check the ravages of the locust in Spain. It 
appeared that considerable apprehension had been felt in many parts of 
Spain that the crops of various kinds would suffer greatly this year from the 
locust; and the Cortes had already voted a large sum to enable the Govern- 
ment to take measures to prevent this calamity, and by a circular addressed 


XV 


to the Provincial Governors by the Minister of ‘Fomento,’ published in 
the Official Gazette, they were directed to make use of the military forces 
stationed within their respective districts, to aid the rural population in this 
object. It was stated that thirteen provinces were threatened with this 
plague.

Mr. Douglas made some further remarks on the “ Corozo nuts,” known _ 
as vegetable ivory, exhibited by him at the last meeting, which were 
attacked by a beetle belonging to the genus Caryoborus. ‘The attention of 
the officials of the Dock Company had been drawn to the serious loss of 
weight that would be found when the nuts were to be delivered, and they 
were anxious to ascertain if there was any mode of arresting their depreda- 
tions, and whether the beetles lived and bred among dried nuts, or entered 
the kernel in an earlier stage. It was suggested that the mischief originated 
in the parent beetles laying their eggs in the nuts when still in a green or 
soft state, and as there were several larvee in each nut the interior was 
completely destroyed. ‘he metamorphosis took place inside the nut. 

Mr. M‘Lachlan, in connexion with the above, exhibited another species 
of palm (Copernicia cénifera), from Rio Janeiro, forwarded to him by 
Professor Dyer, which were also infested with a species of Caryoborus 
(C. bactris, Linn.). In this case each nut served as food for a single larva 
only, which bored in it a cylindrical hole of considerable size and depth. 

Mr. E. A. Fitch exhibited the seeds of a leguminous plant (an article of 
commerce) imported from Egypt, infested by a Bruchus, which was esti- 
mated to cause a loss of 50 per cent. to the owners. 

The President exhibited the larva of an Australian species of Hepialus 
(he believed from Queensland), bearing a fungus with four or five different 
branches, issuing from the back of the neck and the tail. Also, a fungus 
growing from the back of a Noctua pupa. 

Mr. Fryer exhibited a curious variety of one of the Geometridae, believed 
to be Melanippe rivata. 

Mr. M‘Lachlan, on behalf of Dr. Atherston, of South Africa, exhibited a 
pair of a very singular Orthopterous insect (belonging to the Acrydiide), 
which, in colour and in the granulated texture, so exactly mimicked the 
sand of the district as to render it almost impossible to detect it when in a 
quiescent state. The name of the insect was uncertain, but it was supposed 
to approach the Trachyptera scutellaris, Walker. Also some singular oval, 
flattened cases, open at each end, and from six to eight lines in length, 


XV1i 


formed of silk, to which was externally fixed a quantity of fine light brown 
sand. ‘The cases were found under stones in sandy districts, and were 
stated by Mr. Charles O. Waterhouse to belong to a beetle of the genus 
Paralichas (one of the Dascillide). Also the cases of a species of Oiketicus, 
of peculiar structure; the inner lining of the tube was, as usual, composed 
of toughened silk, but to this was attached, externally, a quantity of fine 
sand, and outside this a number of small angular pebbles, only the tail-end 
_ bearing a few rather long twigs and species of grass stems: thus the cases 
differed from those of most species in which substances exclusively vegetable 
were attached externally, the addition of the pebbles making the cases 
(which were nearly two inches in length) unusually heavy. 

The President read descriptions and exhibited drawings of two very 
singular forms of Coleopterous insects from Mr. A. R. Wallace’s private 
collection. or the first, which belonged to the family Telephoride, he 
proposed the generic term Astychina, remarkable for the form of the two 
terminal joints of the antenne, which were modified in one sex into what 
appeared to be a prehensile apparatus, different from anything in the insect 
world, but of which some analogous forms were found to occur in certain 
Entomostracous Crustacea. ‘The other belonged to the family Cleride, and 
was named Anisophyllus, differing from all known beetles by the extremely 
elongated branch of the ninth joint of the antenne. 

Mr. Smith read descriptions of new species of Hymenopterous insects 
from New Zealand, collected by Mr. Charles M. Wakefield. The number 
of known Hymenoptera from New Zealand appeared to be about forty- 
eight.

Mr. Douglas exhibited the following Psyllide, taken by himself near 
Lee, Kent, viz. :— 

Psylla ? On birch trees. Possibly P. Betule, Linn., Flor. 

» spartiophila, Forst. On broom bushes. 

Aphalara venosa, Forst. New to the British Fauna; now first identified 
as living on Achillea millefolium. 

Rhinocola aceris, Linn. On maple trees (Acer campestris). 

ri ericé, Curtis. On heather. 

The President showed some microscopic slides containing specimens of 
Diptera, &c., prepared with extraordinary care by Mr. Enock. He also 
brought for exhibition twigs of horse-chestnut from Oxford, that had been 
attacked by some kind of larva, which had eaten away the inside of portions 
of the stem, causing the buds to drop off. He was in doubt whether the 
mischief had been caused by Zeuzera AMsculi, or by Tortricide, or wood- 
boring beetles, but he would be glad to know if the destruction to the 
trees had been noticed elsewhere. He also exhibited two species of 
Coccus, one of them on Camellia leaves in his greenhouse, which he 
had previously described in the ‘ Gardener’s Chronicle,’ under the name 
of C. Camelliz, and which had afterwards been observed by Dr. Ver- 
loren in his greenhouse in Holland. The female, which is one line in 
length, discharges a white waxy matter, having the appearance of the 
excrement of a young bird. The other species had been sent to him by the 
Rev. T. A. Preston, of Marlborough, on a species of Euphorbia, obtained 
from Dr. Hooker, of Kew. The leaves were covered with small scales, 
which, on close examination, were observed to have two small spines 
attached, and these proved to be the caudal extremities of the males. 
These insects emerge from the pupa backwards, and in consequence they 
make their appearance with the wings drawn forwards over the head. 

Mr. Stevens exhibited varieties of some British Geometre, and what 
appeared to be a small variety of Lyczna Thetis (Adonis), taken near 
Croydon.

Exhibitions, &c. 


Mr. Stevens exhibited specimens of Tillus unifasciatus and Xylotrogus 
brunneus, taken on an oak fence at Upper Norwood. These insects did not 
appear to have been taken near London for many years. 

Mr. Forbes exhibited a specimen of Quedius dilatatus (a parasite in 
hornets’ nests), taken by him at sugar in the New Forest. 

Mr. Champion exhibited Harpalus 4-punctatus, Dendrophagus crenatus, 
Leptura sanguinolenta (female), Amara alpina (female), Cryptophagus 
parallelus and Omosita depressa, all taken at Aviemore, in Inverness- 
shire. 

A letter was read from T. V. Lister, Esq., of the Foreign Office, trans- 
mitting, for the information of the Entomological Society, a copy of a 
despatch from Sir John Walsham, Her Majesty’s Chargé d’Affaires at 
Madrid, relative to the plague of locusts, together with a box containing speci- 
mens of the insect, and a number of earthen egg-cases, each containing from 
thirty to forty eggs. The despatch stated that the Official Report showing 
the progress of the plague and the steps taken to exterminate the insect had 
not yet been published, but a copy would be sent to the Society in a few 
weeks. It was said that the damage done by the locusts this year was 
considerably less than that of last year, owing to the number of soldiers 
which the Government had been enabled to employ since the war was over 
to assist the inhabitants of the districts where the plague existed in 
destroying the insects. The insects sent were stated to be specimens of 
Locusta migratoria, but on examination they were ascertained to be the 
Locusta albifrons, Fab. (Decticus albifrons, Savigny). 

Mr. M‘Lachlan exhibited a series of thirteen examples of a dragonfly 
(Diplax meridionalis, Selys), recently taken by him in the Alps of 
Dauphiné, between Grenoble and Briangon (the exact locality being near 
the village of La Grave, at the base of the ‘ Aiguille du Midi’), remarkable 
for the extent to which nearly all were infested by the red parasite described 
by De Geer as Acarus libellulee (perhaps a species of Trombidium). Of the 
thirteen examples captured casually only one was free from parasites, the 
number of them on the others being respectively 7, 8, 9, 15, 17, 19, 28, 
47, 51, 73, 96 and 111, or a total of 481 on twelve individuals. They were 
firmly fixed on the nervures towards and at the base of the wing, almost 


xxii 


invariably on the under side; but whatever might be the number on any 
particular dragonfly it was always divided nearly symmetrically on the two 
sides of the insect—those much infested having a very pretty appearance, 
from the wings looking as if spotted with blood-red. He had no doubt that 
the Acari must have attained their position by climbing up the legs of the 
dragonfly when at rest; probably they did not quit it till the dragonfly died, 
or perhaps they died with it, so firmly were they fixed. He remarked that 
the history of the Acari was involyed in much obscurity, for it appeared by 
no means certain that all those existing could ever gain access to dragon- 
flies ; just as in the case of the bed-bug and the human-flea, where there 
must be myriads that never have an opportunity of tasting human blood. 
He further noticed that, at the meeting of this Society on the 1st of August, 
1864, he exhibited a dragonfly from Montpellier similarly attacked, and it 
was recorded as Diplax striolata (Tr. Ent. Soc., 2nd series, vol. ii., Proc. 
xxxvi.). This was an error, the insect being D. meridionalis, which seemed 
to be particularly subject to attack. 
Mr. F. Smith read the following :— 


Note on Nematus gallicola, Steph. 


“ This is one of the commonest species of sawfly found in Europe; it is 
the maker of the well-known red galls so plentiful on leaves of different 
species of willow. The galls are, as Mr. Cameron observes, in his com- 
munication to the ‘Scottish Naturalist,’ somewhat local, but they are 
extremely abundant in many situations. I have on many occasions collected 
large quantities of leaves, more or less covered with galls, and have bred 
many hundreds of the flies—all proving on examination to be females. 
Mr. Cameron observes, in the paper alluded to, ‘The male is quite 
unknown to me, and this appears to have been also the case with Hartig.’ 
Last spring I collected, in the London district, a quantity of the galls, 
placing them in a large flower-pot half-filled with garden mould. The larvae 
soon quitted the galls and buried themselves in the mould for the purpose 
of undergoing their transformations. About a month after this the flies 
began to issue forth, probably to the number of from five to six hundred: 
among this number I had the satisfaction of finding two males. This sex 
closely resembles the female, but has a narrower body, longer antenne, and 
the tip of the abdomen is pale; the abdomen is also narrower, and not, as 
in the female, widened towards the apex. ‘This season I have repeated my 
experiment, and have obtained a single male out of several hundreds of 
flies. 

“‘Mr. Cameron further observes, ‘In all probability they, like Cynips 
(lignicola) Kollari and other Cynipide, propagate without the aid of the 
male sex.’ This observation was undoubtedly made in ignorance of the 
discovery made by Mr. Walsh in 1868. In the ‘ American Naturalist’ for 


XX111 


that year, the author records the fact of having himself bred both sexes of 
Cynips spongifica from the galls of the black oak of North America. These 
galls resemble those of Cynips Kollari, being globular, rather larger than 
the European galls, but of the same hard woody consistency externally, 
and of the same spongy substance inside. Mr. Walsh adds, ‘ By the fore- 
part or middle of June both male and female gall-flies eat their way out 
of a certain number, say about one-fourth part; the remainder are not 
developed until about two months later.’ In a private communication 
from Mr. Walsh, I learnt that he had, like myself, bred hundreds of the 
gall-flies from galls collected late in the autumn, all these proving to be 
females, and that it was not until he made collections of galls in summer, 
when a partial development of flies takes place, that he obtained the male, 
this sex being as one to many hundreds of females. At length he bred 
three males, one of which he kindly forwarded to me, and which | exhibited 
at a meeting of this Society. Following up Mr. Walsh’s method of collecting 
the galls of Cynips Kollari early in the season,—that is, just at the time 
when they are becoming hardened, and before any flies have escaped from 
the fresh galls,—I have tried, but hitherto without success, to obtain males 
of Cynips; but I advise all who are interested in the matter to pursue the 
same plan, always remembering that these mysteries of nature are only 
unfolded at intervals, and then only to favoured votaries. 

“With respect to the obtaining of males of Nematus gallicola, I believe 
that any one may collect, even early in the season, thousands of the galls of 
that insect without obtaining a male; but in all probability, by persevering 
season after season, his efforts will, as in my own case, be crowned with 
success ; but I feel assured that unless the galls are gathered before any 
of the flies have escaped, he will have little or probably no chance of 
success. The same care must also be taken in collecting the galls of 
Cynips Kollaxi; collecting them early, just at.the time when they harden 
and become woody, for it is out of the flies first developed that the male 
may be expected to be found. My having bred thousands upon thousands 
of flies without obtaining a male should prove a stimulus to others, for that 
a male exists I think Mr. Walsh has determined beyond question. The 
impregnation of a single female may possibly be sufficient to render her 
progeny, and their descendants, for several generations, equally fertile; and 
the same may possibly be the history of Nematus gallicola. The male bred 
by Mr. Walsh is said not to belong to the restricted genus Cynipss but to 
one not represented in Europe. This may be the case; but in all essential 
generic characters it agrees in a remarkable manner: ‘spongifica,’ like 
Cynips proper, has thirteen-jomted antenne; the neuration of the wings is 
the same, and no difference is perceptible in the construction of the legs; 
the differences that are perceptible are in its abdomen being less com- 
pressed, and it is glabrous; there may be some other minor differences ; 


@ xxiv 


the form of the thorax is apparently the same as that of Cynips. ‘The 
question, ‘ Has Cynips a male?’ remains, in the opinion of those who have 
attentively studied the group, unanswered; but surely more differences 
must exist between ‘spongifica’ and the members of the restricted genus 
Cynips than a less compressed abdomen, and the absence of the downy 
pile that is observable on the sides of the abdomen of Cynips Kollari and 
its allies.” 


A discussion ensued, in which Messrs. Dunning, M‘Lachlan, E. A. 
Fitch and others took part, it appearing to some of the Members that there 
was still a considerable amount of uncertainty as to the precise generic rank 
of the presumed male Cynips. 


Papers read. 


The President, who was unable to be at the Meeting, forwarded a paper 
entitled, “ Notes on the Habits of a Lepidopterous Insect, parasitic on 
Fulgora candelaria, by J. C. Bowring, with a Description of the Species, by 
J. O. Westwood,” accompanied by drawings of the insect in its various 
stages. This curious insect, resembling a Coccus, had been brought to this 
country twenty-six years ago by Mr. Bowring, and on his return to India 
he had succeeded in rearing it to its perfect state, proving it to be the larva 
of a Lepidopterous insect, the general appearance of which induced the 
Professor to place it among the Arctiide. The larve were found attached 
to the dorsal surface of the Fulgora, and as they grew had a cottony 
covering, which also occurred in the pupa state (a period which appeared to 
be of very variable duration). ‘The evidence appeared to prove that the 
larvee fed on the waxy secretion of the Fulgora, and the cocoon of the 
pupa was formed of the same substance. Prof. Westwood had previously 
noticed this extraordinary insect at the meeting of the British Association 
at Oxford in 1860, under the name of Epipyrops anomala. 

The Rey. R. P. Murray forwarded a paper by Mr. W. H. Miskin, of 
Brisbane, containing ‘ Descriptions of New Species of Australian Diurnal 
Lepidoptera in his own Collection.” 

Mr. Edward Saunders communicated the third and concluding portion of 
his “ Synopsis of British Hemiptera-Heteroptera.”

Exhibitions, &c. 
Mr. Edward Saunders exhibited the following rare insects, chiefly from 
the neighbourhood of Chobham :— 


HEMIPTERA. 
Corizus maculatus. 


Plociomerus luridus. é 

Macrocoleus tanaceti, male and female (the female only known previously). 

Chlamydalus pygmaeus, Zett. = Tytthus insignis, D. & 8. From Wim- 
bledon. 

Nabis flavomarginatus (developed). 

» Powerit, B.S. 

Acanthia hirundinis. From nest of house martin, taken on the window- 

sill of a house. 


HYMENOPTERA. 


Odynerus reniformis, 0. sp. 
Astata stigma, male (the female only known in Britain previously). 


Ceropales variegata. 
Ellampus Panzeri. 


Mr. Jenner Weir exhibited a specimen of Lyczena Icarus, which had a 
hollow horn-like protuberance, fixed in front of the head, exactly between 
the antenne. He was disposed to think the adherent object was the theca 
of a moss from which the operculum had fallen off and the spores had 
escaped. The insect had been taken by the Rey. F. Freeth, Rector of Liss, 
in the county of Southampton. 

Mr. Weir also exhibited specimens of the harvest-bug (Leptus autumnalis) 
in-the six-legged larval state, and detailed the excessive irritation they had 
produced by their attacks on himself. Probably in consequence of the dry 
summer, they had been unusually numerous; he had counted eighty pustules 
caused by the Acarus in one of his feet, and as they extended over the front 
of his body as high as the arms, he calculated he could not have had less than 
four hundred pustules at one time; they did not attack the back or the arms: 
he found that sponging the body with vinegar allayed the irritation and pre- 
vented the attacks, but the application of the remedy caused the wounds 
produced to smart very much. He found them most plentiful amongst 
leguminous plants, as sanfoin, red clover and French beans. He could 
plainly perceive the pest running rapidly over his boots whenever he went 
amongst the plants mentioned. The larger specimens were red in colour, 
but the newly-hatched young were whitish. 

Mr. F. Smith remarked that on one occasion when he was in the Isle of 
Wight he had suffered very much from this annoying pest, and he. found 


XXVll 


that by taking a dose of “ milk of sulphur” he was effectually relieved from 
all annoyance. 

Professor Westwood communicated a note with reference to some shoots 
of horse-chestnut which he had exhibited at the July meeting of the Society, 
as having been destroyed, apparently by some Lepidopterous larvee or wood- 
boring beetles; but he had since received from Mr. Stainton some shoots 
that had been forwarded to him by Sir Thomas Moncrieffe, which had been 
destroyed by squirrels in precisely the same manner. Sir Thomas had 
himself seen the squirrels at work splitting the shoots with their teeth and 
extracting the pith. 

Mr. Smith remarked that he had found the common buff-tip moth 
(Pygera bucephala) very destructive of late to the Spanish chestnut, a tree 
on which the insect is not usually found. 

Professor Westwood also stated that he had received from a correspondent 
in Oxfordshire specimens of the two small species of grasshopper with long 
antennze, Meconema varium, F’ab., and Xiphidion clypeatum, Panzer, which 
he had taken on a pear tree in his garden, where they had been regularly 
observed for the last five or six years. 

Mr. M‘Lachlan stated that the former insect was frequently observed by 
Lepidopterists when sugaring for moths. 

Mr. Smith communicated the descriptions of three additional species of 
Formicide from New Zealand, which had been sent to him by Mr. David 
Sharp since his description of Mr. Wakefield’s collection was in the press. 
Two of the species belonged to genera not previously ascertained to inhabit 
New Zealand, namely Amblyopone and Ponera. 

Mr. F. Smith exhibited a series of sixty specimens of a sawfly (Cresus 
septentrionalis), which he had bred from larve found feeding on young 
shoots of the alder, growing on the banks of the Sid, near Sidmouth, South 
Deyon. The specimens of the fly were all bred in a single flower-pot, nine 
inches in diameter. 

Mr. Smith also mentioned the fact of Mutilla Europa having been found 
parasitic on Bombus muscorum, by Miss M. Pasley, in an orchard at Shed- 
field Grange, near Wickham, Hants; he also remarked on a coincidence 
‘ somewhat remarkable, that on the day previous to his receiving Miss Pasley’s 
communication, Prof. Edward Brandt, of St. Petersburg, had informed him 
that he had found Mutilla Europea in a nest of Bombus muscorum; this 
being the first instance that had come to his knowledge of the parasite 
infesting the nests of that species of humble-bee. 

Dr. Sharp communicated the following list of localities of some species 
of Amazonian Staphylinide discovered by Dr. Trail, and described by 
Dr. Sharp in the ‘ Transactions of the Entomological Society of London,’ 
1876, pp. 27—424 :—

Election of a Member. 


Mons. Alfred Preudhomme de Borre, of Brussels, Secretary of the Belgian 
Entomological Society, was balloted for and elected a Foreign Member. 


Exhibitions, &c. 


_ Mr. Bond exhibited, on behalf of Mr. N. Cooke, of Liscard, near Birken- 
head, a female variety of Hepialus humuli, pale in colour, and with the 
usual markings; three fine specimens of Crymodes exulis; fifteen very fine 
dark (some nearly black) specimens of Kpunda lutulenta; and six specimens 
of the new Tortrix, Sericoris irriguana. All the above were taken near Loch 
Laggan this season. 


- XXX 


Mr. Stevens mentioned that a specimen of Callimorpha Hera (the Jersey 
tiger-moth) had been taken at St. Margaret's Bay, near Dover. 

The Secretary read a note from the Rey. Fitzroy Kelly Lloyd, of Pitten- 
weem, N. L., enclosing for inspection a worm measuring two inches in 
length, extracted from the abdomen of an earwig. Mr. Pascoe said that it 
was one of the Nematode worms, and was probably a Filaria. 

Mr. Forbes exhibited a weevil (evidently not indigenous to Britain), taken 
alive amongst some Orchids at Highgate, supposed to have been imported 
from Ecuador. Mr. Pascoe pronounced it to be a Cholus. He subse- 
quently gave the following diagnosis, under the name of 


Cuoius ForBeEst. 
C. ovatus, niveo-squamatus, maculis nudis aterrimis variegatus, quarum 
una in medio elytrorum majuscula, supra rugoso-punctatus; rostro 
pedibusque fortiter punctatis. Long. (rostr. excl.) 5 lin. 


Mr. William Cole exhibited several series of specimens of Ennomos 
angularia, which he had bred, from eggs laid by the same female, with a view 
to ascertain whether any changes could be traced to the influence of the 
food-plant. The result went to show that no marked change in colouration 
took place in the specimens which were fed on oak, hawthorn, lime or lilac, 
although, taken as a whole, they were all less richly yellowish than a 
number of specimens taken at large, a series of which was exhibited for the 
sake of comparison. As was to be expected, the size and fineness of the 
specimens varied much with the change of food, oak producing the largest, 
and lilac the meanest specimens. 

Mr. Enock exhibited microscopic slides Beta some beautiful pre- 
parations of Polynema ovulorum, one of the Proctotrypide, and other minute 
Hymenoptera. 

A letter was read from Mr. E. Higgins with reference to some specimens 
of Deilephila Euphorbie, exhibited at a meeting of the Society on the 17th 
of September, 1873, which were then stated to have been captured in the 
larva state in the neighbourhood of Harwich. Some doubt was expressed 
at the time, as it was stated that the food-plant did not grow in that neigh- 
bourhood; but about fe eae of September last he had visited Harwich, 
in company with Mr. E. W. Janson, and they were afterwards joined by 
Mr. Durand (from w ee he had received the specimens of D. Euphorbie), 
who undertook to show them the place of capture, and they not only found 
the food-plant growing there, but in three other places nearly half a mile 
further on. 

Paper read. 

Mr. Frederick Smith communicated “ Descriptions of new Species of 

Cryptoceride belonging to the Genera Cryptocerus, Meranoplus and 


XXX1 


Cataulacus,” accompanied by a plate containing figures of all the species, 
twelve in number; thus raising the number of species described by him to 
forty-eight. The descriptions were preceded by some interesting particulars 
relative to the habits of these insects, especially of Meranoplus intrudens, 
which constructs its formicarium in the thorns of a species of Acacia, some 
four to five inches in length; and at a distance of about half an inch from 
the pointed end a small round hole was made by the ants, which served for 
ingress and egress to and from the nest. The thorns contained a kind 
of spongy pith, in which the channels and chambers of the nest were 
constructed. 


New Part of the Society’s Catalogue of British Insects. 

«A Catalogue of the British Hemiptera-Heteroptera and Homoptera 
(Cicadaria and Phytophthires),” compiled by Messrs. J. W. Douglas and 
John Scott, was on the table. This was the fifth Catalogue of British 
Insects published by the Society.

Eehibitions, dc. 
Mr. F'. Smith exhibited some remarkable specimens of thorns from 
Natal and Brazil, which had been taken possession of by certain species of 


@M xxxii 


Cryptoceridw for the construction of their formicaria: some of them were 
as much as three inches in length. 

Mr. Champion exhibited a bug sent by Mr. Walker from Besika Bay. 
It was figured in Guerin’s Mag. de Zool. under the name of Mustha 
spinosula. 

Professor Westwood mentioned that a caterpillar had been forwarded to 
him from Deal, the captor complaining that he had suffered from considerable 
irritation of the skin, caused by the hairs of the insect, and that the irritation 
had continued for a week afterwards. It was the larva of Lasiocampa rubi. 

The Professor exhibited a singular Coleopterous larva, from Zanzibar, of 
a flattened, ovate form and a stecl-blue colour, with two points at the 
extremity of the body and with long clavate antenne: the head bore some 
resemblance to that of the Dipterous genus Diopsis. He also exhibited a 
specimen of the butterfly Hesperia Sylvanus, received from the Rey. Mr. 
Higgins, of Liverpool, having the pollinaria, apparently of an orchid, 
attached to the base of the tongue. Also the bulb of an orchid, purchased 
by Mr. Hewitson with a collection of roots from Ecuador, which was found 
to contain nine living specimens of cockroaches, comprising six different 
species, viz., Blatta orientalis, Americana, cinerea, Madere, and two others 
unknown to him, some being of considerable size. 

Professor Westwood alluded to the varied nature of the collection recently 
exhibited at the “ Exposition des Insectes utiles et des Insectes nuisibles,” 
in Paris, and remarked on the absence in the list of exhibitors of the names 
of many distinguished French entomologists. 


Mr. Dunning read the following :— 


Note on Acentropus. 


“Tn the Transactions of the Entomological Society of the Netherlands 
for the present year (Tijd. vy. Entom. xix. 1), Heer Ritsema has published 
a Second Supplement to his ‘ Historical Review of the genus Acentropus ;’ 
and the author, writing in June, 1875, prefaces it with the welcome 
announcement that he has worked up the literature to the present time, 
‘as in all probability I shall be able in this summer to complete the history 
of the mode of life and the different stages of A. niveus.’ 

“ Whether this expectation has been fulfilled, either in 1875 or 1876, 
I do not know. But, however this may be, I am sure Heer Ritsema will 
be glad to learn that, though he and I failed to convince Newman that the 
genus is properly placed in the Lepidoptera, we did make a convert of 
Doubleday. In a Supplement to his ‘Synonymic List of British Lepi- 
doptera,’ published in 1873, Doubleday for the first time admitted 
Acentropus into that order. Its precise place in the order is not indicated, 
but it is immediately followed in the Supplement by a species of Ebulea 


XXXili 


(Botyde), which sufficiently shows that the position which Doubleday 
would assign to Acentropus is in or near the Hydrocampide. 

“Tt may possibly be remembered that, in a paper which the Society did 
me the honour to publish in the ‘ Transactions’ for 1872 (pp. 121 and 281), 
I adduced some arguments tending to show that there is really one species, 
and one only, of this genus; and in a note on p. 156, the position is thus 
summed up;—‘I am quite in accord with Ritsema when he says that 
A. Hansoni, Garnonsii, Neve, badensis and germanicus are not specifically 
distinct from A. niveus; but I go a step further, and say that A. latipennis 
is identical with A. Hansoni.’ Ritsema is now satisfied that A. latipennis 
is identical with A. Hansoni, but still thinks that there are two species, of 
which one (A. niveus, Oliv. = A. Garnonsii, Curt.) has a female with 
rudimentary wings, and the other (A. latipennis, Méschl. — Zancle Hansoni, 
Ste.) has a female with normally developed wings. Doubleday, in the 
Supplementary Catalogue already mentioned, does not go into the synonymy 
at length, but records one species only, under the name of A. niveus, giving 
latipennis as a variety, thus :— 


AcENTROPUS NIvEUS. Niveus, Olivier? 
latipennis, Moschl., var. 


“T am not able to throw any further light on the specific identity or 
distinctness of the two forms. Ritsema, however, refers to his having found 
many specimens, all males, at Arnheim, and to the capture at Huissen 
(near Arnheim) of a winged female, which he recognises as A. latipennis. 
‘ By this capture’ (says he, at p. 15), ‘I am fortified afresh in the opinion 
that there are two species..... For it would be otherwise inexplicable that 
amongst the innumerable winged individuals captured by me at Overween, 
not a single female occurred, and that I, by breeding from larve coming 
from the same place, obtained only females (in number already amounting 
to fifteen), which were furnished with wing-rudiments and live in the water, 
whilst the first specimen that is captured at Huissen, inside the house at a 
lamp, is a female with well-developed wings.’ I must confess that I cannot 
follow this reasoning. Be it remembered that no difference is suggested in 
the males from the different localities, and the supposed distinctness of the 
species rests entirely on the possession by the females in the one case of 
developed and in the other of rudimentary wings. From Arnheim and 
Huissen, males, and one winged female captured; from Overween, males, 
and fifteen unwinged females bred. Hrgo, two species! Surely this is a 
non sequitur. It is, in fact, a repetition of Brown’s argument (with which 
I dealt in the ‘Transactions’ for 1872, p. 142), that the winged female 
occursjin one locality, and the apterous females in another locality. I can 
scarcely see how the facts mentioned by Ritsema can be said to fortify any 

F 


@xxuy 

opinion one way or the other. So far from proving the duality, they are 
quite consistent with the unity of the species. And recalling the facts that - 
Curtis and Dale took both forms of female at Glanville’s Wootton, that 
Brown bred the apterous and McLachlan captured the winged form at 
Burton, and lastly that Ritsema himself, in 1870, found pup at Haarlem 
from which two females emerged, of which one had rudimentary and the 
other well-developed wings, I venture to hazard a conjecture, that if Ritsema 
perseveres with his breeding from Overween larve, he will obtain some 
females with wings as ample as those which flew to the lamp at Huissen. 

“Tn conclusion, one word of regret, a tribute to Members this Society 
has lost. In the short period since the publication of my former paper on 
Acentropus, of those to whom I then referred as living authors, death has 
removed no less than three—Henry Doubleday, Edward Newman and

Election of Members. 

M. Eduard Grube, Director of the Zoological Museum of the University 
of Breslau, and Dr. Katter, of Putbus, in the Island of Riigen, were balloted 
for and elected Foreign Members. Lord Dormer, formerly a Subscriber to 
the Society, was re-elected a Subscriber. 


Exhibitions, dc. 

Mr. McLachlan (on behalf of Mr. W. Denison Roebuck, of Leeds) ex- 
hibited some locusts, a swarm of which had been observed to pass over 
Yorkshire during last autumn. He had examined the specimens carefully, 
and had compared them with the descriptions of the two species which 
occasionally visited this country, viz., Pachytylus migratorius and P. cine- 
rascens; and he had come to the conclusion that the specimens belonged to 
P. cinerascens, which he remarked was supposed to breed in some parts of 
the north of Europe, and therefore might be expected more frequently in 
this country. 

Mr. W. C. Boyd exhibited living larve of Brachycentrus subnubilus, in 
their quadrilateral cases, reared from the eggs. They were of much larger 
size than those previously exhibited by him at the November meeting in 
1873, being more than half an inch long. 

Mr. S. Stevens (on behalf of Mr. Edwin Birchall) exhibited a specimen 
of Cirrhcedia xerampelina, var. unicolor, Agrotis lucernea, var. latens, and 
what appeared to be a small var. of Zygena filipendule, with the pupa-case 
and cocoon. They were all taken by Mr. Birchall in the Isle of Man. 

Mr. Meldola referred to a request made by Mr. Riley at the meeting in 
July, 1875, that entomologists would supply him with the cocoons of the 
parasite, Microgaster glomeratus, which were much wanted in America to 
destroy the numerous specimens of Pieris rapee which had been imported 
into that country. Mr. McLachlan had at a subsequent meeting stated 
that M. glomeratus was parasitic on P. brassicee, but doubted if it ever 
attacked P. rape, and Mr. Meldola now exhibited the insects he had found 
parasitic on these two species—that on P. rape being Pteromalus imbutus, 
Waltl. (one of the Chalcidide), while on P. Brassice he had observed 
Microgaster glomeratus and a Dipterous species, Tachina augusta. Speci- 
mens of all of them were exhibited. Mr. E. A. Fitch remarked that Van 
Vollenhoven had obtained Pimpla examinator from P. Napi. 

Mr. Smith stated that he had received a nest of Osmia muraria, sent 
to him from Switzerland. The cells were empty, the Osmiz having taken 


oon 


their departure, but one closed cell was observed to contain a yellow larva, 
which ultimately proved to be that of a beetle belonging to the Cleride, 
Trichodes alvearius. 

Mr. Hamilton James, of Truro, forwarded a photograph of a specimen of 
Deiopeia pulchella, taken on the 12th October last at Portscatter, near 
Falmouth, stating that it was considered a very rare insect in Cornwall. 

Sir Sidney S. Saunders exhibited a large box of insects of all orders, which 
had been collected in Corfu by Mr. Whitfield, and were now for sale. 

Sir Sidney Saunders also exhibited several larvee of Meloide in their first 
stage, received from M. Jules Lichtenstein, of Montpellier, consisting of— 

1. The primary larval form of Sitaris Colletes (Mayet), found on Colletes 
succincta, feeding on ivy-blossoms in September, the former described by M. 
Valéry Mayet in the ‘ Annales’ of the French Entomological Society, 1875. 

2. The same larval stage of Mylabris melanura obtained from the egg, 
which M. Lichtenstein had not succeeded in rearing to the second stage. 
Like other larve of Meloide in their primary form, it is furnished with 
triple tarsal appendages. A description of this larva will appear in the 
aforesaid ‘ Annales.’ 

3. The exuvie of the primary larva of Meloé cicatricosus (from the egg), 
and also the second stage of the same larva, still bearing legs. 

4. The primary larva of Meloé proscarabeus (?), differing from the 
foregoing in the structure of the antenne. Taken on an Andrena. 

5. The corresponding larval stage of Meloé autumnalis (?), also differing 
as aforesaid. ‘Taken on Scolia hirta. 

Also specimens of the Phylloxera of the vine in various stages, con- 
sisting of—a. The root-type; b. The leaf-gall type; c. The winged stage ; 
d. The male of the apterous sexual race. 

Mr. C. O. Waterhouse made some remarks on the ‘Catalogus Cole- 
opterorum’ of Gemminger and y. Harold, the concluding volume of which 
was now published. The total number of generic names given is 11,618, 
of which 7364 are adopted genera, and 4254 appear as synonyms. The 
total number of species recorded is 77,008. Dejean’s first Catalogue, 
published in 1821, gave 6692 species, while that of 1837 (the third edition) 
gave 22,399 species, of which, however, only a portion were then described. 
Taking into consideration the number of species described during the 
publication of the Munich Catalogue, the number of described species at 
the present date could not be less than 80,000. Thus, since 1821, the 
known species of Coleoptera had increased twelvefold. 

Mr. C. O. Waterhouse read “ Descriptions of Twenty New Species of 
Coleoptera from various Localities.” 


XXXVli 


ANNUAL MEETING, 


January 17, 1877. 
Sir Srpnry SurrH Saunpers, C.M.G., Vice-President, in the chair. 


An Abstract of the Treasurer’s Accounts for 1876 was read by Mr. 
Dunning, one of the Auditors, showing a balance of £6 8s. in favour of the 
Society. 

The Secretary then read the following ;— 


REPORT OF THE CoUNCIL FoR 1876. 


In accordance with the Bye-Laws, the Council begs to present the 
following Report :— 

During the year 1876 the Society has elected twenty-three new 
Members or Subscribers, and has lost ten by death or resignation. Among 
the losses by death is that of Edward Newman, who was an original 
Member of the Society, one of the first Council, and filled the office of 
President in the years 1853-4. 

The ‘ Transactions’ for the year (exclusive of the ‘ Proceedings’) form a 
volume of 655 pages, containing twenty memoirs, with twelve plates, of 
which two are coloured. ‘The Society has to thank Mr. Wakefield for the 
plate of New Zealand Hymenoptera, and Professor Westwood and Mr. Smith 
for the plates in illustration of their papers. And a second donation of 
£10 by Mr. Robinson-Douglas, to be applied to the publication of papers 
on British or European Entomology, has been appropriated to the memoirs 
on British Hemiptera, which have been contributed by Messrs. Edward 
Saunders and John Scott. 

Another part of the ‘ General Catalogue of British Inseets’ has also been 
issued, comprising the Hemiptera (Heteroptera, and the main portion of 
the Homoptera), for the compilation of which the Society is indebted to 
Messrs. Douglas and Scott. 

No less than six Compositions or Life Subscriptions have been received, 
_ and of these five have been invested in augmentation of the Reserve Fund, 
whilst the remaining one has been applied in the purchase of books. The 
additions to the Library, both by donation and by purchase, have been 
many and valuable; and a large number of books and pamphlets have 
been carefully collated and bound, 


evil 


The stock of ‘ Transactions’ for the five previous years has been made 
up into volumes, and the colouring of the plates has involved considerable 
outlay, from which, however, a return will be gradually received. 

The total expenditure for both ordinary and extraordinary purposes has 
amounted to £609. It is satisfactory to find that the ordinary income 
would have sufficed to meet the ordinary outgoings, but it has only been by 
special donations that the Council has had it in its power to accomplish all 
that has been done, and the Society is indebted to Mr. Dunning for a 
donation of £150. 

The financial account for the year may be thus summarized :—

The Bye-Laws have been reprinted, with the alterations adopted by the 
Society ; and twenty-eight Town Members have availed themselves of the 
new regulation (see Chap. 15) enabling them to secure, by prepayment 
of half-a-guinea, the same advantages in respect of the receipt of the 
‘Transactions’ as are enjoyed by our Country Members. It is hoped 
that other Town Members will take advantage of the Rule, under 
which the ‘Transactions’ are forwarded to them by post on the day of 
publication. 

The most important alteration effected in the Bye-Laws was that by 
which the Society, adopting the suggestion contained in the last Annual 
Report, determined to appoint a Member of the Council to the office of 
Librarian. Leaving the ministerial duties connected with the Library to a 
salaried Sub-Librarian, the object of the Council was and is to obtain 
the services of some Member of our body whose acquaintance with ento- 
mological literature will enable him to advise the Council in all matters 
connected with the Library, whose linguistic acquirements will facilitate 
correspondence and the maintenance of friendly relations with Ento- 
mological Societies abroad, and whose avocations will permit of his 
attending at stated times at the Society's Rooms to render assistance to 
those wishing to consult the contents of our shelyes—in short, an officer 
whose special object it shall be to see that the Library is made worthy of 
the Society’s position and advances with it, and whose special aim it shall 


KXXIX 


be to give such help to students and others as shall render our Library 
most available for the purposes of research or reference. Instead of once 
a-week, as previously, the Library has, during the past year, been open 
every day; the frequent visits of our Members, and the number: of 
volumes borrowed, sufficiently attest the need for, and the convenience of 
this arrangement; and in order to give still further effect to the policy of 
making the Library as accessible and useful as is possible, the Society has 
this evening to put the new Bye-Law in force, and proceed to the election 
of an Honorary Librarian. 

In conclusion, the Council feels justified in saying that this year has not 
been one of inactivity. The number of our Members, both at home and 
abroad, has become somewhat larger; our Library grows, and is increasingly 
used; our meetings maintain their interest; and our publications, both in 
extent and scientific value, are equal to those of any former period of the 
Society’s existence. 


11, Chandos Street, Cavendish Square, 
17th January, 1877. 


The following gentlemen were elected Members of Council for 1877 :— 
Sir Sidney Smith Saunders, Professor Westwood, Rev. A. E. Eaton, Rev. 
T. A. Marshall, and Messrs. H. W. Bates, G. C. Champion, J. W. Douglas, 
J. W. Dunning, F. Grut, R. Meldola, E. Saunders, H. T. Stainton, and 
J. Jenner Weir. 

The following officers were subsequently elected for the year 1877 :— 
President, Professor Westwood, M.A., F.L.S., &c.; Treasurer, J. Jenner 
Weir; Hon. Secretaries, Messrs. F. Grut and R. Meldola; Hon. Librarian, 
Rey. 'T. A. Marshall. 

The President (Prof. Westwood) having been unfortunately prevented 
from attending by an accident, the reading of his Address on the progress 
of Entomology for the past year was unavoidably postponed until the next 
meeting, on the 7th February. 

A cordial vote of thanks was given to the President, with an expression 
of regret at the cause of his absence on this occasion. A vote of thanks 
was also given to the Treasurer and Secretaries; and a special vote in 
acknowledgment of Mr. Dunning’s munificent donation of £150, towards 
the extraordinary expenses of the Society.

THE PRESIDENTS ADDRESS. 


GENTLEMEN, 

In commencing the Address which the custom of the 
Society has, I think advantageously, rendered an annual neces- 
sity, I must again return you my best thanks for the renewed 
honour you have conferred on me in electing me your President ; 
expressing at the same time my conviction that you would have 
acted more wisely, and for the greater good of the Society, had 
you chosen a younger and more active member of the Society for 
the office, and one who, resident in London, could have taken a 
more continuous share in its affairs. 

The Report from the Council, which you have heard read, and 
which will be appended to this Address, will have shown you the 
position of the Society both in regard to its pecuniary state and 
as to the increase of new, and decrease by death of several of our 
long much-valued members, as well as the greater and more 
liberal facilities for usefulness which have been introduced into 
its administration, and which in my humble opinion ought to 
insure an enlarged support. And here I cannot avoid calling 
your attention to the extreme liberality of several of our members, 
who, seeing the advantages of such increased facilities, and the 
necessity of the publication of various valuable memoirs laid 
before the Society (such as those offered to the Ray Society, 
which, except for the means of publication adopted by that 
‘Society, would never have seen the light), have, by their renewed 
contributions with no unsparing hand, enabled the Society to 
publish them, and to effect the other measures mentioned in the 
Report of the Council. Other Societies for the advancement of 
our Science in other countries, receive Government help, and I 
cannot but think that it is a false policy to withhold from a small 
Society like ours, which has for so many years been doing good 
and beneficial work, a portion of that support which is granted to 
other better endowed and chartered Societies. Let us hope that 

G 


a more liberal policy may soon be adopted by the “ruling 
powers.” 


OBITUARY. 


We have to lament the loss by death of four of our members— 
Edward Newman, Edwin Brown, Trovey Blackmore, and Jacob 
Birt. Of these Edward Newman stands in the foremost rank, as 
one of the few of the foundation members which time had spared 
to us. | 

Epwarp Newmay, F.L.S., F.Z.S., &c., was born on the 138th 
of May, 1801, and died on the 12th of June, 1876. From a 
biographical notice published as a preface, or rather postscript, 
to the last volume of ‘The Zoologist,’ it appears that from his 
earliest childhood he was devoted to the observation of natural 
objects, especially plants, birds, and butterflies. This general 
love of Nature was seen throughout all his future long and most 
active life, and resulted in the publication of his works on ferns, 
the ‘ Dictionary of British Birds’ (a re-issue of Montagu, with 
additions from Selby, Yarrell, &c.), ‘ Birds-nesting,’ the ‘ Illus- 
trated Natural History of Britsh Moths’ and its companion 
volume of British Butterflies, the ‘ Letters of Rusticus,’ but more 
especially in his establishing, editing, or extensively contributing 
to various miscellaneous works on Natural History, as the ‘ Zoolo- 
gist,’ the ‘Hntomological Magazine,’ the ‘Entomologist,’ the 
‘ Phytologist,’ the ‘Field,’ the ‘Young England,’ the ‘ Friend,’ &c., 
in all of which great numbers of his articles are to be found. Of 
entomological works his ‘Sphinx Vespiformis’ was an ingenious 
parody on MacLeay’s ‘ Hore Entomologiz,’ in which he futilely 
attempted to arrange natural objects, even down to genera, in a 
septenary system, and which he endeavoured further to develop 
in some of his papers in the ‘Entomological Magazine’: his 
‘Grammar of Entomology’ was, as it has been termed in the 
‘ Zoologist,’ “a most useful little work;” his ‘Insect Hunters’ 
was a clever paraphrase of the last-named work in Hiawathi 
verse, and, thanks to the very excellent wood engravings, his 
‘British Butterflies’ and ‘ British Moths’ are of lasting value, 
although the title of the last-mentioned work is deceptive, as the 
extensive families of Pyralids, Tortricide, Tineide, and Aluci- 
tide are omitted, and although the work does not contain a single 
figure of the preparatory states of any of the species. From the 


xiii 


memoir in the ‘ Zoologist’ it now appears that in addition to the 
numerous articles which he published in his own name, he 
assumed at different times the ‘“‘ various pseudonyms, ‘ Corderius 
Secundus,’ ‘EK. N. D.,’ ‘ Rusticus,’ and others.” The memoirs 
published under his own name up to the year 1860 are recorded 
in Dr. Hagen’s ‘Bibliographia Entomologica,’ but it is desirable 
that a complete list of his subsequent works, including those 
which he published under fictitious names, should be given to the 
public. 

Epwixn Browy, of Burton-upon-Trent, died on the Ist of 
September last, aged fifty-seven. He was a general naturalist, 
and had formed large collections of geological, botanical, and 
zoological specimens, but with an especial predilection for insects, 
of which, regardless of expense, he had amassed a very valuable 
collection. In 1842 he published a notice of Locusta migratoria 
in the ‘Annals of Natural History,’ and in 1863 he contributed 
the entomological portion of Sir Oswald Moseley’s ‘ Natural 
History of Tutbury,’ in which he published an account with 
figures of the preparatory stages of the genus Acentropus, fully 
confirming the opinion which I had ventured to express years 
previously in our ‘'Transactions’ (vol.i., p. 18), that the insect 
belonged to the order Lepidoptera. 

TroveyY Buackmore died on the 3rd of last September, at the 
age of forty-one. He had made a collection of the insects of 
North Africa (which he had visited for the sake of his health), 
but I am not aware that either he or Mr. Jacosp Birt, our other 
lost member, had published any entomological memoir or notice. 
_ Txomas Wiixrnsoy, of Scarborough, died on the 13th of April, 
at the age of fifty-eight years. He was well known as a most 
indefatigable and excellent Micro-Lepidopterist, having carefully 
investigated the life-history of many minute species of moths, of 
which he had discovered a considerable number of new species.* 

The Obituary of our Science during the past year, moreover, 
comprises several other well-known and lamented names. 

Dr. Lupwia Reprenpacuer, the Director of the Imperial 
Museum of Natural History in Vienna, died on the 8th of 
February, 1876, in his sixty-third year. He was educated with 
his brothers in the Gymnasium attached to the Great Monastery 


* The deceased entomologist here alluded to must not be confounded with Mr. 
8, J. Wilkinson, the author of the valued work on British Tortricide. 


ov 

of Kremsminster. From 1834 to 1840 he worked as a voluntary 
assistant in the Vienna Museum. In 1840 he took the degree of 
Doctor in Medicine; in 1851 he was made Professor of Zoology 
in the University of Prague, from whence he was recalled by the 
Emperor to the Museum of Vienna as Custos-adjunct, and in 
1860 the Directorship of the Museum was conferred upon him. 
His chief published works were the Coleopterous part of the 
Fauna Austrize, which has gone through three editions, the same 
portion of the work known as the ‘ Voyage of the Novara,’ and 
his descriptions of the beetles of Kotschy’s collections from 
Syria and Western Taurus. 

Entomology in Vienna has, moreover, experienced a further 
loss in the death of Count JoHAnN ANGELO FERRARI, who had 
for many years been the especial Custos of the Coleopterous 
portion of the Imperial Museum, and who died on the 18th of 
May last. In Munich, also, Dr. Friscumann, the Conservator 
of the Museum of Natural History, died on the 11th of February ; 
and on the 20th of May died Jonann Hernricn Kattrensacn, of 
Aix la Chapelle, who was born on the 30th of October, 1807, at 
Cologne. His principal works had reference to the insects 
destructive to vegetation, and his Monograph of the Aphide is a 
elassical work. 

We have also to lament the death of Herr C. H. Hoprrer, 
the talented assistant to the Entomological Department of the 
Berlin Museum, whose attention was especially devoted to Exotic 
Lepidoptera, of which he published various new species, some of 
which appeared as a second part of Dr. Klug’s ‘Neue oder 
weniger bekannte Schmetterlinge.’ 

The death of Mr. W. 8. Arxryson, of Calcutta, must also 
be recorded. He was a very industrious collector of Lepidoptera 
for many years in India, and we are indebted to him for a 
description and figure of Butanites Lidderdalii, one of the most 
interesting species of butterflies which has ever been published. 
His collections have been purchased by Mr. Hewitson, but the 
Heterocerous portion of them has been transferred to Herr 
Staudinger, although it is understood that the new species are in 
the hands of Mr. F. Moore for publication.

EvoLutTion oF SPECIES. 


The principle of the Evolution of Species is a subject which is, 
at the present time, attracting so great a share of the attention of 
naturalists, as well as of the general thinking public, that it is 
necessary here to allude to such investigations as have been made 
with reference to it in an especial manner upon the objects of our 
study. The question to be solved appears to me to be this :—Do 
the yariations which exist, im a state of Nature, amongst the 
various individuals of recognized species warrant the conclusion 
that the species themselves are only modifications of other 
precedent species, which may themselves be ultimately referred 
back to some supposed primeval type? This field of enquiry is 
far too vast to be more than glanced at in an Address like the 
present, but so far as my own observations—for now more than 
half a century, over the most extensive of all the tribes of Nature 
—extend, I cannot come to any other conclusion than that the 
variations alluded to above never extend beyond the genuine 
limits of the species. I had hoped that long before this time Mr. 
Darwin would have published his promised work on the modifi- 
cations of species in a state of Nature, and it must be evident that 
this will be the true crux of his system. To affirm that the 
discovery of a new species, either fossil or recent, which is found 
to be intermediate in certain portions of its structure between 
already known and distinct forms, is a clear proof that the newly 
discovered species is a descendant from one and a progenitor of 
the other of such known forms, appears to me to be fallacious. 
No entomologist, I venture to affirm, has come to the conclusion 
that Carabus Cychrocephalus, although the intervening link 
between Carabus and Cychrus, is a descendant from Carabus and 
a progenitor of Cychrus, or vice versé. On the other hand, a 
naturalist who believes in a grand and harmonious “ Systema 
Nature,’ whether that be, as Linneus suggested, in the likeness 
of a “mappa geographica” or otherwise, has equal or even 
greater right to assume that these newly-discovered species are 
only so many hitherto unknown intervening links in the great 
scheme of the creation. ‘Osculant groups” and “connecting 
links” are terms well known to zoologists before the publication 
of the ‘ Origin of Species,’ with a definite meaning quite distinct 


@wxivi 


from the idea that they formed the genetic connection between 
the great groups which they serve to connect.* 

A memoir on the ‘‘ Ontogenie” and “ Philogenie”’ of insects, 
by Dr. Paul Meyer, is published in the tenth volume, or vol. 3 of 
the new series, of the ‘ Zeitschrift fiir Naturwissenschaft’ of 
Jena, 2nd Heft. 

A very valuable contribution to the knowledge of the earliest 
stages of many of the higher Crustacea is to be found in ‘ Unter- 
suchungen zur Erforschung der Genealogischen Grundlage des 
Crustaceen Systems —Ein Beitrag zur Descendenzlehre,’ pp. 124, 
folio, Wien, 1876, with nineteen plates and twenty-five woodcuts, 
by Carl Claus. In this work the author gives the most careful 
descriptions and figures of the larvee or zoea states of numerous 
species of Paleemonide, Squillide, Nebalia, Sergestes, Palinurus, 
Scyllarus, Pagurus, Porcellana, Maia, Inachus, &c., with addi- 
tional descriptions and details of the Copepoda, Cirripedia, 


* In the course of his introductory lecture to the Natural History Class in the 
University of Edinburgh at the commencement of last November Term, Prefessor 
Sir Wyville Thomson made reference to the evolution hypothesis. He said that the 
great stumbling block, from the natural history side of the question, in the way of 
our at once accepting the evolution hypothesis, was that any such passage from one 
species to anything but that, was entirely outside our experience. The horse 
evidently had been the horse since the earliest hieroglyphs were engraved on 
Assyrian monuments and tombs; and the same held for all living creatures. 
There was not a shadow of evidence of one species having past into another during 
the period of human record or tradition. Nor was this all: we had, in the fossil 
remains contained in the rocks, a sculptured record of the inhabitants of this world, 
running back incalculably further than the earliest chisel mark inscribed by man— 
incaleulably further than man’s existence on this planet; and although we found 
from that record that thousands of species had passed away, and thousands had 
appeared, in no single case had we yet found the series of transitional forms imper- 
ceptibly gliding into one another and uniting two clearly distinct species by a 
continuous bridge, which could be cited as an undoubted instance of the origin of a 
species. Profound mystery still involved the birth of the new specific forms. Mr, 
Darwin’s magnificent theory of “ natural selection” and the “ survival of the fittest,” 
had undoubtedly shaken the veil by pointing out a path by which it was conceivable 
that such an end might be attained; but it had by no means raised it, for every new 
instance which he produced and deyeloped with such eloquence and skill, of the 
marvellous changes which animals underwent under varying conditions, somehow 
always appeared to emphasize the fact that, however far variations might be carried, 
the limit of specific identity was in our experience never overpassed. Still, even if 
we never found out the precise mode in which one species gave rise to another, there 
could, he believed, be no further hesitation in accepting generally a hypothesis of 
evolution, and in regarding our present living races as the ultimate twigs of a great 
genealogical tree whose gradually coalescing branches we could trace downward, if 
our information were complete, to the dawn of geological time,

Ostracoda, Phyllopoda, and Urphyllopoda, terminating with the 
Trilobites, Merostomide, and Xiphosura, &c., endeavouring to 
deduce from the forms of the larve the comparative development 
or descent of the higher Crustacea from the lower. The forms of 
some of these preparatory states are certainly amongst the most 
bizarre of the Annulose sub-kingdom. The book is dedicated to 
Charles Darwin. 

A remarkable memoir by W. J. Schmankewitsch on Artemia 
salina and Miilhausenii, and on the genus Branchipus, is pub- 
lished in Von Siebold and Kolliker’s ‘ Zeitschrift’ (Bd. xxv., 
Suppl., noticed in ‘ Nature,’ June 8, 1876), in which the author 
asserts that he had observed that Artemia salina, found in a salt 
lake near Odessa, had gradually undergone a change in the form 
of the extremity of its post-abdomen, according to the degree of 
saltness of the water; the bifurcation of this part of the body 
gradually diminishing, as well as the number of its terminal 
sete, until the tail became rounded at its extremity, with only a 
slight central notch, agreeing in this respect and also in the then 
smaller size of the animal, with Artemia Miilhausenii of Fischer 
(Bull. Mose. t. 7). The opposite experiment also showed that 
even in a few weeks the latter species became altered in the 
direction of A. salina, which last species, by the still greater 
dilution of the salt water, is asserted to have been transformed in 
the third generation into a Branchipus agreeing with the latter in 
the post-abdomen having one more segment. Hence it is assumed 
that the direct influence of changed conditions of life may in the 
course of a few generations transform one species, or even one 
genus, into another, and this in both directions. This statement, 
however, appears to me to require much further investigation 
than appears to have been bestowed upon it. We know, in fact, 
from the researches of Vaughan Thompson (Zool. Researches, 
No. 5, pl. 2, fig. 9), that the extremity of the post-abdomen of the 
nearly perfect Artemia salina is rounded with a slight central 
notch, and without any spines, and that the differences between 
the terminal appendages of Artemia salina and Branchipus, as 
well as their mouth-organs, ignored by our author, are very 
great, whereas there is not the slightest difference between 
the extremity of the body of A. salina and that of its supposed 
passage to Branchipus as figured by Schmankewitsch, beyond the 
division of the long terminal segment of Artemia into two apparent 


Piviii 


segments in the supposed transitional individuals. Can it be 
possible that Artemia Miilhausenii may be an imperfectly retarded 
condition of A. salina, similar to the imperfect state of the great 
majority of individuals of Lygeeus brevipennis, or Velia rivulorum ? 
I attach but little weight to the parthenogenetic observations in 
this memoir, as we know perfectly from various English Lepi- 
doptera that parthenogenesis affords no test of specific distinction. 

In ‘Nature’ for December 28, 1876, appears an article ‘‘ On 
the Relation between Flowers and Insects,” translated from the 
‘Bienen Zeitung,’ the author of which assumes that the capacity 
for gathering honey either for the sustenance of the insect or its 
progeny is to be regarded as the test of the evolutionary process 
employed in the development of these insects; the author 
remarking that ‘the habit possessed by our honey-bee of feeding 
itself from flowers, and its corresponding faculty of deciding 
amongst different species and divining the situation of the honey, 
is, in the first instance, derived from the common parents of all 
the. Hymenoptera. It probably even comes from such remote 
ancestors as the leaf-cutting wasp (sic),* from thence passes to 
the gall-flies, the Ichneumons, and the hunting wasps, from 
which latter it goes to the allied species of ants and bees.” This 
extraordinary series of assumptions is founded upon a set of 
tables showing the number of visits paid to flowers in which the 
honey is apparent, partially apparent, concealed but easily 
reached by a short or by a long proboscis or not reachable, or 
which are only furnished with pollen, commencing with Tenthredo 
and ending with “ Bombus apis” (sic). Even supposing these 
various tables were correct, I feel called on to insist that they 
would afford no proof at all that a bee is a more fully developed 
creature than a Tenthredo, or that a bee- which. makes waxen 
hexagonal cells furnished with honey has been developed out of a 
wasp which makes paper hexagonal cells furnished with animal 
food; or that a Bombus which makes individual egg-shaped 
waxen cells provisioned with honey must be regarded as the 
forerunner of the hexagonal cell-making honey-bee. 

A memoir of considerable extent on the markings of caterpillars 
at different stages of their growth (that is, after successive 
changes of the skin) appears as the chief article in the second 


* Throughout the article the leaf-cutting Hymenoptera are ignorantly miscalled 
leaf-cutting wasps.

volume of Dr. August Weismann’s ‘Studien zur Descendenz 
Theorie,’ Leipzig, 1876, large 8vo, with five coloured plates; the 
first division of the memoir being entitled ‘‘ Ontogenese und Mor- 
phologie der Sphingiden-Zeichnung,” and the second division 
“Ueber den Phyletischen parallelismus bei metamorphischen 
arten.” The first four plates illustrate the variations in the 
colours and marks of the larve of the Sphingide, and the fifth 
those of Saturnia Carpini, one or more segments of the body in 
different specimens and varieties being represented: 225 pages of 
small print are occupied in the discussion of this subject, to which, 
as appears to me, far too much importance has been attached. 

Every fact, however, bearing on this curious question deserves 
to be carefully investigated, even if it extend no further than the 
darker or lighter colour of certain broods of insects. In this country 
Lycena Artaxerxes offers a curious instance of this subject. 

It is, moreover, well known that in certain localities, especially 
in the northern parts of England and Scotland, certain pale- 
coloured moths assume a darker coloration, and thus, as we learn 
from an article on ‘“ Melanism,” by Mr. Edwin Birchall, F.L.S. 
(Entom. M. Mag., November, 1876, p. 131), near Leeds, Aplecta 
nebulosa and Xylophasia polyodon are often perfectly black, and the 
“black pepper” (Biston betularia, var.) is well known, although, as 
described by the late R. S. Edleston in ‘ Newman’s Entomologist’ 
(ii. p. 150) sixteen years previously, it was almost unknown near 
Manchester. The dark variety had, however, so much increased 
subsequently that he considered the original pale type of the 
species would soon be extinct in the locality. Mr. Birchall 
‘speculates (sensw Darwiniano) on the causes of the melanism, and 
gives a list of the species of moths of which melanic varieties occur 
in the northern and western parts of the British Islands. The 
subject has been, however, carried much further by Dr. F. 
Buchanan White (Ent. M. Mag., December, 1876) by whom the 
430 (or thereabouts) species of Macro-Lepidoptera inhabiting 
Scotland are subjected to an analysis in this point of view; the 
majority appearing not to exhibit any decided variation. Certain 
species, however, offer variation in any locality. ‘The remaining 
species are thus divided :— 

A. Melanochroic species. 

1. Melanochroic races (amongst which it is remarkable that 
the extreme northern form of Aplecta occulta is pale). 
H 


- | 
2. Species frequently Melanochroic, but often not so. 

B. Leucochroie species. 

1. Species of which all or a majority of the individuals are 
paler than in the South. 
2. Species frequently paler, but not invariably so. 

Like Mr. Birchall, Dr. White believes that ‘natural selection” is 
the chief cause of this variation, although meteorological influences 
may have led to the first production of the melanochroism. 

The permanently dimorphic condition of various insects has 
been long known. Vanessa prorsa and levana, Lycena amyntula 
and polysperchon, and Anthocharis belia and ausonia, have been 
satisfactorily determined to be respectively the summer and 
winter forms of three species. Dr. Weismann entered into and 
extended this subject amongst the Pierides in his ‘Studien zur 
descendenz Theorie’ (vol. i.), and we have recently received an 
account of a series of experiments on Papilio Ajax and its 
supposed allied species, Walshii, Marcellus, and 'Telamonides, by 
Mr. W. H. Edwards, which appears to confirm Dr. Weismann’s 
views that the cold of winter modifies the broods produced in the 
autumn, developing markings which have been regarded as 
characteristic of distinct species. 

A curious instance of the modification of specific characters in 
a species occurring in an American locust—Tragocephala Virgin- 
iana, Fabr., (Gryllus, v.) viridifasciatus, De Geer, and Locusta 
infuscata, Harris—is given by Mr. 8. H. Scudder (Proc. Boston 
Soc. xvil. p. 481), in which, in addition to permanent variations 
of colour in the specimens from New England, Texas, and 
Florida, variations are tabulated in the antenne, fastigium of the 
vertex, pale spots in the tegmina of the males, and cloudiness of 
the wings. 

A memoir with figures on the “mimicry” exhibited by the 
species of the genus Leptalis as compared with other Pieride, by 
Fritz Miiller, appears in the ‘Jenaische Zeitschrift fiir Naturwis- 
senschaft,’ 10th Band, neue folge, 3rd Band., Heft 1, 1876. 


GEOGRAPHICAL DISTRIBUTION. 


The geographical distribution of insects is a subject which is 
attracting increased attention, and to which additional interest is 
attached since the publication of Mr. A. R. Wallace’s work, ‘ The 
Geographical Distribution of Animals, with a Study of the 


li 


Relations of Living and Extinct Faunas as elucidating the Past 
Changes of the Earth’s Surface,’ two vols., 8vo, London, 1876. 

The distribution of the earth into primary geographical regions, 
proposed by Mr. Sclater, has been partially adopted—(1) the 
Palearctic, comprising the whole of Europe, North Africa, and 
the whole of Asia, except the Indian and Siamese Peninsulas ; 
(2) the Nearctic Region, comprising the whole of North America, 
except Mexico and the Nicaraguan Isthmus; (8) the Neotropical 
Region, or the whole of South America, and with Mexico and the 
Isthmus of Nicaragua; (4) the Ethiopic, or the whole of Africa 
(except the northern part) and Arabia; (5) the Oriental Region, 
comprising India, Burmah, Siam, Sumatra, Java, Borneo, and 
the adjacent islands; and (6) the Australian Region, comprising 
New Holland, New Zealand, and the other islands east of 
Borneo. 

The causes regulating the geographical distribution of animals, 
fossil and recent, are discussed, and the animals characteristic 
of each of these regions are rapidly passed under review, the 
greater part of the second volume being occupied by a systematic 
sketch of the chief families of land animals in their geographical 
relations. In this part of the work insects occupy only thirty- 
four pages, being devoted to the distribution of the genera of 
Diurnal Lepidoptera (comprising nearly 8000 species), and a few 
of the families of beetles. 

The Distribution of Insects in New Hampshire (forming a 
chapter from the first volume of the Report upon the Geology of 
that State), by S. H. Scudder, affords much material for study. 
Probably no State in the Union presents so striking a variety in 
animal life as New Hampshire, its northern and southern portions 
belonging to distinct Continental forms, part resembling the 
productions of Labrador and Greenhill, whilst at a difference of 
only sixty miles animals flourish characteristic of sub-tropical 
climates. A considerable portion of the memoir is occupied 
with the distribution of the different species of butterflies, and a 
portion with the different Orthoptera, the habits of the species of 
this order being given in great detail, together with the musical 
notes of each species. 

The butterflies and Orthoptera collected by Mr. Dawson along 
the boundary line between British America and the United States, 
have also been described by Mr. Scudder.

A few notes on the insects of Kerguelen’s Land, by H. N. 
Moseley, M.A., naturalist to H.M.S. ‘ Challenger,’ are published 
in the ‘Journal of the Linnean Society ’ (Zool. vol. xii. p. 578). 


Fossa, Enromouoey. 


In the ‘Memoirs of the American Association for the Advance- 
ment of Science’ (vol. i.), a very elaborate treatise is published 
by Mr. S. H. Scudder on fossil Lepidopterous insects, nine 
species of which are described and figured in detail, and various 
additional fossils are described which have been regarded as 
Lepidopterous, including the Paleontina oolitica, which, from a 
careful examination of the original specimen and its cast in the 
Jermyn Street Museum, he has determined not to belong to the 
Lepidoptera, but most probably to the Cicade. Mr. Scudder 
has also published a short notice on the fossil Orthoptera of the 
Rocky Mountain Tertiaries ; also on the fossil Coleoptera of the 
same stratum (of which he describes thirty: one species). Also 
the description of the fossil abdomen of a larva dragonfly from 
the Carboniferous Slate from Cape Breton; and also the descrip- 
tions of several fossil species of Thripside from the North 
American Tertiaries, including two new genera, Lithadothrips 
and Paleothrips. Also a note on the fossil insects of Cape Breton 
(Proc. Boston Soc. N. H., vol. xviii. p. 113). 

In the ‘Memoirs of the Boston Society of Natural History’ 
(vol. ii., part 2, No. 3), Mr. 8. H. Scudder has also published an 
article [on the carboniferous myriapods preserved in the Sigil- 
larian stumps of Nova Scotia. 

Notices of a fossil species of scorpion in the British coal- 
measures, also of some new macrurous Crustacea from the Kim- 
meridge-clay and from Boulogne-sur- Mer, and of a new fossil crab 
from New Zealand have been communicated to the Geological 
Society of London by Mr. H. Woodward, who has also described 
an extremely interesting fossil insect from the coal-measures of 
Scotland in the Quart. Journ. Geol. Soc. Lond. 1876 (vol. xxxii., 
p- 60, pl. 1x.), belonging, as it would appear, to the family Mantide, 
under the name of Lothomantis carbonarius, and which agrees, 
in the remarkable development of the prothoracic lobes, with the 
African Blepharis domina, and which also seems to have a near 
relationship with the singular fossil named Eugereon Boeckingii, 
by Dr. Anton Dohrn. Mr. Woodward has added a list of all 


liii 


the known Paleozoic fossil forms with which he was acquainted; 
to which Mr. Scudder has made a very important addition in his 
communication to the ‘ Geological Magazine’ for November, 1876, 
in which a list is given of the Orthopterous, Neuropterous, Arach- 
nidous, and Myriapodous fossil American insects from the 
Carboniferous formation, with reference to the works in which 
they have been described. 

Professor Oswald Heer has also, in the same paper, supple- 
mented Mr. Woodward's list by noticing four species of fossil 
Blattide previously recorded by him in the ‘ Viertelzahreschrift 
d. Tiihner Natur Gesellsch,’ 1864. 

A new species of fossil Cypris (Paleocypris Edwardsti) has 
been described by M. Ch. Brongniart in the ‘ Geological Maga- 
zine’ for January, 1877. 


Anatomy, PHystoLoaGy, AND METAMORPHOSIS. au 


Space will not allow me to do more than shortly allude to the 
continuation of Sir John Lubbock’s very elaborate series of 
experiments with ants, bees, and wasps, published in the 
‘Proceedings of the Linnean Society’ (Zool. vol. xii. p. 415), 
with a view to ascertain the amount of intelligence and the 
means of communication which these insects possess amongst 
themselves. By carefully marking certain individuals, and then 
submitting them to various tests of a curious character, the 
author appears to have arrived at a conclusion contrary to the 
generally-received opinion as to.their intellectual powers. His 
observations have been further directed to the provident habits of 
ants, the division of labour, their affection and behaviour to their 
wounded brethren, their recognition of friends, their senses of 
smell and hearing, their sentiments of benevolence; also to the 
appreciation of colour by bees and wasps, and the capacity for 
work of wasps, their power of distinguishing colours, and on the 
direction of the flight of bees. 

The stridulation of certain insects, and the mechanical con- 
trivances by which it is effected, has long attracted the attention 
of entomological anatomists, especially in the Cicade and 
crickets. It has also been observed in some species of butterflies. 
The ‘Transactions’ of our Society (new ser., vol. il., p. xcviii.), 
contain a notice by the Rev. Joseph Greene on the production 
of a faint hissing sound made by a peacock butterfly (Vanessa Jo), 


@ iiv 
the wings of which were simultaneously depressed and elevated. 
This was confirmed by Mr. Hewitson in vol. iv. Proce. p. ii. 

In the ‘ Entomologist’s Monthly Magazine’ for January, 1877, 
is a paper by Mr. Swinton detailing the structure of the basal 
portion of the wings and the serrated structure of the anal vein of 
the fore wing, and the smooth raised surface of the costal vein of 
the hind wings. Figures of these structures, by which the sound 
is produced when they are rubbed together, are added. The 
author seems to have overlooked the curious notice of the 
production of a similar sound in the butterflies of the genus 
Ageronia observed by Mr. Darwin (see Gen. Diurn. Lep. i. p.82). 

Mr. Wood-Mason has made us acquainted with a curious 
instance of stridulation observed by himself in an Indian spider 
(Annals Nat. Hist., Jan. 1876). 

An elaborate memoir on a very delicate portion of the internal 
anatomy of lepidopterous insects first noticed by Newport, has been 
published in Hofmann’s ‘ Niederlandisches Archiv. fiir Zoologie’ 
(Bd. iii., Heft 2, 1876), with the title “‘ Ueber das sogenannte Bauch- 
gefiiss der Lepidoptera nebst einigen Beobachtungen uber das 
sympathische nervensystem dieser insectenordnung,” specimens of 
all the different tribes of Lepidoptera from the Papilionide to the 
Pterophoride having been carefully dissected and described. 

A memoir of the internal spinning apparatus of Lepidopterous 
insects, by Helm, has been published in Siebold and Kolliker’s 
‘ Zeitschrift’ (vol. xxvi. Heft 4). 

A remarkable memoir by Dr. O. J. B. Wolff appears in the 
‘Nova Acta Acad. Natur. Curios.,’ vol. 38, Dresden, 1876, 4to, 
with eight plates, in which the author has investigated the minute 
anatomy of various portions of the structure of bees (Apis, 
Prosopis, and Hyleus), especially with reference to the mechanism 
of the mouth-organs and respiratory organs of the thorax and 
abdomen. The author does not appear to have been acquainted 
with the description and figures which I gave of the progressive 
action of the parts of the month in Anthophora in my ‘ Introduc- 
tion,’ from a state of quiescence to the full extension of the 
sucking apparatus, which is, I think, better shown in that insect 
than in any other of the bees. 

A memoir on the “ Metamorphoses of Tipula oleracea and 
Musca carnaria,” by Mr. A. Hammond is reported in the ‘ Journal 
of the Quekett Club’ for May last.

An anatomical memoir on the structure of the eyes of Dipterous 
insects has been communicated to the Academy of Bologna by 
M. G. V. Ciaccio (Rendiconto, p. 99), of which a translation of 
the summary appears in the ‘Journal de Zoologie,’ of M. Paul 
Gervais (Tom. v. No. 4). 

An article on the digestive apparatus in insects, by M. Jousset,

A paper upon the structure of the palpi of male spiders, by 
J. H. Emerton, appears in the Proc. Boston Soc. xvii. p. 505. 

In ‘ Nature,’ November 2, 1876, is the account of an experiment 
upon the caterpillars of Pieris Brassice at the time of their 
assuming the pupa state, by J. A. Osborne. Of nine of these 
caterpillars he cut through the silken girdle they had spun, thus 
bringing them to the condition of the Suspensi: of these three 
managed to secure hold of the caterpillar skin until they had 
fastened themselves by their anal hooks to the silk to which the 
anal feet of the larve had been attached; the others fell to the 
ground for want of the suspensory girdle. 

M. Balbiani has continued his curious researches on the eggs of 
the Phylloxera and their development, quoted in the ‘Comptes 
Rendus’ for 20th and 27th November last. 

A memoir on the gynandromorphism of the Lepidoptera, with 
especial description of two specimens of Saturnia (Callosoma) 
Promethea, partly male and partly female, is given by A. S. 
Packard, jun., M.D., in the Memoirs of the Boston Society of 
Natural History (vol. 11. pl. iv. No. 111). In one of these insects 
the right side of the body and antenne are male, the right wings 
partly male and partly female, and the left side of the body and 
wings are male. In the other specimen the right half of the 
insect is male and left half female. 

The last part of the ‘ Verhandlungen’ of the Natural History 
Society of Prussian Rhine district (Corresp. Bl., p. 98), is a notice 
by D. v. Hagen on Hymenopterous gynandromorphic specimens 
occurring in Prosopis obscurata, Schenck, Nomada glabella, 
Thomson, Sphecodes reticulatus, Th., Andrena fuscipes, Ponera 
androgyna (T’horell, Switzerland). Reference is made to others 
described in the Berlin Ent. Zeitschr. for 1878, and the Stettiner 
Ent. Zeitsch. for 1861.

The existence of monstrous specimens of Lepidopterous insects 
in which the head case of the caterpillar is retained in the 
butterfly state has long been known, the first instance on record 
being the Phalena heteroclita of Miiller, represented in the 
Memoirs of the French Academy. Professor Wesmael subse- 
quently published an account and figure of a similar monstrosity 
in Nymphalis Populi, and Dr. Hagen has supplemented these by 
a beautiful figure of Morpho Eurylochus, still retaining the head 
of the larva. Numerous other instances are recorded by Dr. 
Hagen in his paper on these monsters in the Memoirs of the 
Museum of Comparative Zoology at Harvard Coll. Mass. (vol. ii. 
No. 9). 

A short article on the partially retarded development of 
specimens of both sexes of Anisopteryx vernata and pometaria 1s

The interesting peculiarities exhibited in the development of 
the Crustacea from the egg to the perfect state continue to attract 
much attention. A memoir on this subject by Mr. Spence Bate, 
containing descriptions of the larve of thirty-eight genera of 
Podophthalmous Crustacea, has been presented to the Royal 
Society. The memoir of Dr. Claus on this subject has been 
noticed above. 

A memoir by F. W. Putnam on the habits of the blind crayfish, 
and the reproduction of lost parts, is published in Proc. Boston 
Soc. N. H. xvii. p. 16. 

M. Hesse has continued his memoirs on the rare and new 
Crustacea from the coasts of France in the ‘ Annales des Sciences 
Naturelles’ (vol. ili. of the sixth series of the zoological part of 
that work), containing a memoir on the development of the larve 
of the Paguride, and vol. iv. Ser. vi. (47th year) comprising 
* Nouvelles Observations sur les Métamorphoses embryonnaires 
des Crustacés de l’ordre des Isopodes sédentaires,” and descrip- 
tions of two new species of the parasitic genera, Athelgus and 
Pleurocryptus, belonging to the family Bopyride. The plates 
accompanying this memoir are in the usual style of the author’s 
designs. 

A memoir on the habits of the hermit crabs, by M. Agassiz, 
has also been quoted (Ann. Nat. Hist., Jan. 1876). 

A very important memoir “On the Development of Lepas

Rudolf von Willemées-Suhm,* naturalist to the ‘ Challenger’ 
Expedition (by whom a very interesting paper containing new 
forms of Crustacea was presented to the Linnean Society in the 
preceding year), appears in the ‘ Philosophical Transactions’ of 
the Royal Society of London for the year 1876. The discovery 
that in Lepas the larve pass through a Cypris state was made by 
Burmeister. He, however, missed the intermediate stages, and 
Claus discovered and illustrated the final metamorphosis into 
the fixed barnacle. The author was fortunate in being able to trace 
all the stages of the transformations of this wonderful creature 
during the voyage of the ‘ Challenger,’—that which occurs from 
the final Nauplius form, with six gigantic spines (which = the 
Archizcea of Dohrn) to the free-swimming spineless Cypris form, 
and thus to the sedentary fixed condition of a small barnacle, are 
not surpassed by the most remarkable instances of transformations 
in the Annulosa. 


DrscrRIPTIvE ENTOMOLOGY. 


This branch of the Science has, as usual, attracted the especial 
attention of the greater number of entomological students. To 
so great an extent has this been carried that it would be im- 
possible for me, in the limits of this Address, even to give a list 
of the various memoirs and shorter articles which have appeared 
in the different Transactions,-Annals, and Magazines devoted to 
Natural History in general, or to Entomology in particular. This 
would also be comparatively useless labour, as the publication of 
the ‘ Zoological Record’ annually brings us a condensed summary 
of these additions to our knowledge. I must, however, allude to 
some of these memoirs of a more important character, either from 
their containing valuable anatomical or other information not 
contained in more technically descriptive papers. 

In our own country Messrs. Rye and Sharp have added various 
new species to our lists of British Coleoptera. 

In Hymenoptera, Messrs. Cameron and Marshall have done the 
same, the former having especially devoted his attention to the 
Tenthredinide and Cynipide, as the latter has to the Ichneu- 
monidee. ; 

* Dr. Willemées-Suhm died on the 18th of September, 1875, in his twenty-ninth 


year. He had previously to the ‘ Challenger’ Expedition been “ privat-docent” in 
the University of Munich, under Professor von Siebold.

The Trustees of the British Museum have issued a second, 
much improved, edition of Mr. I’. Smith’s excellent monograph 
of the English bees. 

Synoptical Catalogues, in a too condensed form, of the Scotch 
Coleoptera by Messrs. Blackburn and D. Sharp, and of the 
Scotch Lepidoptera by Dr. F. Buchanan White, have been con- 
tinued in the ‘ Scottish Naturalist’ for the past year. 

In English Lepidoptera the additions have been chiefly con- 
fined to the description of the larvee of previously known species, 
and for which we are indebted to Messrs. W. Buckler, G. T. Porritt, 
C. Fenn and the Rey. J. Hellins. We can but regret to see so 
little new on the Micro-Lepidoptera from Myr. Stainton’s pen. 

In the Suctorial Hemiptera of Linneus our Society has done 
good service by the recent publication of the Catalogues of 
British Heteroptera and Homoptera, and by the excellent 
‘Synopsis of British Species of Heteroptera,’ by Mr. Edward 
Saunders, in our ‘Transactions.’ Messrs. Scott and Douglas 
have continued their additions to the species of these groups 
(especially the Homoptera), in the pages of the ‘ Kntomologist’s 
Monthly Magazine,’ and the excellent monograph on British 
Psyllide in our Transactions. 

Mr. Buckton’s monograph on the Aphide will be noticed below. 

In British Diptera we are indebted to Mr. Verrall for articles 
on the interesting family Dolichopide, and to Mr. Meade for a 
memoir on the difficult genus Sarcophaga, both published in the 
‘Entomologist’s Monthly Magazine.’ 

A separate work entitled ‘Sketches of British Insects,’ by the 
Rey. W. Houghton, has appeared. 

The members of the Society are probably aware that the 
Trustees of the Collection of British Lepidoptera of the late 
Henry Doubleday have placed it in the Bethnal Green Museum. 
A memorial with reference to its exhibition and preservation 
having been presented by the Haggerston, the Kast London, the 
South London, and the West London Entomological Societies, 
elicited a reply from the Director of the South Kensington 
Museum (of which that of Bethnal Green is a branch), in which 
it is stated that a room will be specially provided and an attendant 
will be in readiness to show the collection to such persons as may 
apply to the officer in charge for permission to inspect it. Ina 
further communication from the Director of the South Kensington

Museum, it is stated that arrangements have been made for the 
Doubleday Collection to be open for inspection until 9.30 P.M. on 
Tuesdays; on other days it is open from 10 a.m. till 5 p.m. 

A short notice of the insects collected by Captain Feilden 
during the late Arctic Expedition, so far as they have hitherto 
been unpacked, has been given by Mr. M‘Lachlan in the ‘ Ento- 
mologist’s Monthly Magazine’ for January, 1877, including “five 
or six butterflies, within a few hundred miles of the North Pole”— 
a curious circumstance when it is taken into consideration that 
Iceland and the large islands of the Spitzbergen group, although 
in lower latitudes, have apparently no butterflies. The species 
collected belong to the genera Colias, Argynnis (or Melitza), 
Chrysophanus, Acronycta, Amphidasis, Cheimatobia, Phycis, 
Bombus, Ichneumon, Tachina, Tipula?, Culex, Simulium, and 
various bird-lice. 

In South America, in addition to the excellent work done and 
doing at the Public Museum of Buenos Ayres by our friend 
Dr. Burmeister, we are glad to announce the establishment of an 
“Academia Nacional de Ciencias exactas” in the University of 
Cordova, the capital of the Argentine Republic, and the pub- 
lication of the first volume of its ‘ Acta’ in a handsome 4to form. 

An unexpected instance of the extended cultivation of Ento- 
mology occurs in the last September number of the modern 
Greek periodical entitled ‘ Bupwv’ (Touos B, Puaarawdioy 21), in which 
seven quarto pages are devoted to the subject, the Megos Tproy, 
relating to the general characters and modes of collecting and 
preserving insects with hard wing-covers, the Megos Tetaerov, to 
the clear-winged insects, ‘‘ Onpa Lvtouav Egovrwy Trepuyas Aragpaveis.” 
The article is illustrated with wood-cuts showing the modes of 
pinning and setting insects; and it is to be noticed that the Greek 
collectors prefer to set their Lepidoptera with their wings gradually 
elevated to the tip, just contrary to our English fashion of pinning 
them with the tips resting on the paper of the drawers—a plan 
which is clearly objectionable, as it damages the cilia and offers 
great facilities to mites to eat it off. 

From the Antipodes we have also evidence of an extended love 
for the cultivation of our subject. The establishment of the 
—Tinnean Society of New South Wales” is especially worthy of 
notice. The second and third parts of the ‘Proceedings’ of. 
that body contain memoirs on the Araneides of the Cheyers

Expedition to New Guinea and the adjacent islands, by Mr. H. 
H. B. Bradley, and a short memoir by Mr. W. Macleay on the 
Geodephagous Coleoptera of the same Expedition. 

In the ‘Report of the Proceedings of the Wellington (New 
Zealand) Philosophical Society, on the 18th of last October, the 
President of the Society, Dr. Buller, C.M.G., read a paper on 
“Insect Architecture; or, Notes on the Spider-Wasp of New 
Zealand”—‘‘ a species of spider-wasp (Pompilus), commonly called 
the ‘mason-bee,’ the nest of which consists of a double row of 
cells composed of clay and very neatly finished, each compartment 
being completely shut off from the adjoining one, and _ per- 
manently sealed, when filled with spiders, in the bodies of which 
the wasp deposits her eggs.” In the discussion which took place 
after the reading of the paper seven of the members took 
part. 

The insects of New Zealand are at length beginning to 
attract the attention of English entomologists, as it is evident 
from recent discoveries that their numbers (formerly supposed 
to be but small) are much greater than had- been believed. We 
are indebted to Mr. Miers, of the British Museum, for a valuable 
memoir on the Crustacea of New Zealand, published by the 
Colonial Museum and Geological Survey Department, with 
three plates. 

In the ‘ Transactions of the New Zealand Institute’ for 1875 - 
(vol. viii., May, 1876) we find the following memoirs :— 

“On the Habits of a Trap-door Spider,” by R. Gillies (pp. 222 
to 262). This is a very elaborate paper on an apparently 
new species, and is a careful supplement to Mr. Moggridge’s 
work. 

“Notes on the Coleoptera of Auckland, N. Z.,’ by Captain 
Brown (pp. 262 to 271). 

“Remarks on the Pselaphidse of New Zealand,’ by Captain 
Brown (pp. 271 to 282), containing descriptions of fifteen new 
species, and two new genera, Dalma and Sagola, the latter 
described by Dr. Sharp. 

“Description of a new Genus and Species of Heteromera, 
New Zealand,” by Frederick Bates, F.L.S. Reprinted from the 
‘ Annals of Natural History.’ 

“Description of a Species belonging to the family Satyride,” 
by R. W. Fereday, figured under the name of Oreina ? Othello

(Pluto olim) ; and in the ‘ Entomologist’s Monthly Magazine’ for 
December, 1876, My. Butler has given the scanty list of the 
New Zealand butterflies (fourteen in number*), including a 
new species,—-Chrysophanus Enysi,—allied to C. Salustus. 
Memoirs containing descriptions of new species of New Zealand 
Coleoptera have been published in the ‘ Entomologist’s Monthly 
Magazine’ for the past year (vol. xu.), by Messrs. H. W. Bates 
and D. Sharp; and by Mr. Pascoe in the ‘Annals of Natural 
History’ during the past year. Various new species of Hyme- 
noptera from New Zealand have also been described by Mr. F. 
Smith in the ‘ Transactions’ of our Society. 

In India excellent work is being done at the Museum of 
Calcutta by our friend Mr. Wood-Mason, who appears to have 
devoted much of his attention to the Orthoptera and larger 
Crustacea. His various memoirs on these subjects have been 
reprinted in the ‘ Annals of Natural History.’ 

We must congratulate our brother workers in North America 
on the many admirable works which they have recently pub- 
lished, of most of which notices will be found below. The names 
of John Leconte, Horne, Packard, Scudder, Edwards, Strecker, 
Grote, and various other entomologists, including Dr. Hagen 
and Baron Osten-Sacken, may be well placed side by side with 
the most celebrated European entomologists. 


CRUSTACEA. 


The memoirs of Claus and Spence Bate, on the zoea or larva 
state of various genera of Decapod and Stomapod Crustacea, have 
been referred to above. A memoir on various new species of 
Oxystomatous Crustacea, by Edward J. Miers, F.L.S., of the 
British Museum, has been communicated to the Linnean Society. 
The ‘Transactions of the Connecticut Academy of Arts and 
Sciences,’ vol. i1., part I., 1876, contains a Report on the 
dredgings in the region of St. George’s Banks, in which a number 
of Crustacea were taken, but only one new species is described— 
Stenothoe peltata, Smith, pl. IV., figs. 5 to 8. A memoir on the 
curious crustaceous genus At‘glea, with the description of a 
new species by Fritz Miller, appears in the Jena Zeitschr. f.

Natur Wissensch., 10th Band, 1876. The Rev. T. R. Stebbing 
has continued his researches on the small Amphipodous Crustacea 
of our Southern Coast, and has published several illustrated 
papers on different species in the ‘Annals of Natural History.’ 

An account of the Crustacea inhabiting the Lake Titicaca, 
in Peru, by Walter Faxon, appears in the Bulletin of the 
Museum of Comparative Zoology of Harvard College, Cam- 
bridge, Mass., vol. 11. The Crustacea (with the exception 
of a single species of Cypris) belong to the curious Amphi- 
podous genus Allorchestes, and are remarkable for the 
abnormally developed epimera and tergal spines; some of them 
are also noteworthy as comparatively deep-water forms of a 
family commonly regarded as pre-eminently littoral; woodcuts 
are given of all these curious species. 

A memoir on the terrestrial Isopoda of Austria, with two 
plates, by Herr Vogl, has appeared in the ‘ Verhandlungen’ of 
Vienna. 

An elaborate memoir on the internal anatomy of Branchipus 
stagnalis, with three plates, is published by F. Spangenberg in 
von Siebold and Kolliker’s ‘ Zeitschrift (25 vol. Suppl.), which 
also contains a memoir by Dr. H. Nitsche on the sexual organs 
of Branchipus Grubei of von Dybowsky, with a plate. The 
memoir of Herr Schmankewitsch on the Branchipides, in the 
same volume, is noticed above. 

The ‘Journal des Museum Godeffroy’ (Heft xii. 41, 1876), 
contains the description and numerous figures of a new species 
of Branchipus from Peak Downs, Australia, 8300 miles inland, by 
Dr. Richters, of Altona (B. Australiensis). 

The Niederlandisches Archiy. fiir Zoologie, of Hofmann 
(vol. 111.) introduces us to a new worker amongst the minute 
Crustacea, Dr. P. P. C. Hoek, assistant in the ‘‘ Zootomisches 
Laboratoriums,’ of Leyden, having published a memoir on the 
‘“‘ Susswasser-Copepoden” of the Netherlands Fauna, with three 
elaborate plates of details relating to the genera Cyclops and 
Temora; likewise a memoir on the embryology of the Balanide, 
with two plates. 

A memoir of Herr Claus on the minute anatomy of the 
Daphniide is published in Siebold and Kolliker’s ‘ Zeitschrift, 
vol. 27, Heft 111.

ARACHNIDA. 

The Swedish naturalist, Thorell, has continued his excellent 
labours on the European spiders, and has, moreover, given us a 
new classification of the scorpions (see Ann. Nat. Hist., Jan. 
1876). He-has also published an article on some spiders of 
Labrador (Proceedings Boston Soc. N. H. xvii. p. 490). 

The various articles published on the spiders of North 
America in the Natural History periodicals of that country by 
_ the late N. M. Hentz have been collected into a volume by the 
Boston Society of Natural History, edited by EK. Burgess, with 
notes by J. H. Emerton (Occas. Papers, i1.). 

A-second memoir on the Arachnida Territelarie (Mygalide), 
with three plates, by Dr. Ausserer, has appeared in the twenty- 
fifth volume of the Vienna ‘ Verhandlungen.’ 

The memoir of Mr. R. Gillies on the trap-door spider of New 
Zealand is referred to above (p. 22). 

The Rey. O. P. Cambridge has communicated a memoir on a 
new order and some new genera of Arachnida from Kerguelen’s 
Land, witha plate, to the ‘ Proceedings of the Zoological Society,’ 
1876, p. 258. Also a catalogue of a collection of spiders made 
in Egypt, with descriptions of a new species of a new genus 
(Ibid., p. 541). 

An elaborate memoir by Dr. Anton Specker, of Prague, upon 
the anatomical and histiological characters of Gibocellium, a new 
genus of Opilionideous Arthrogastra allied to the interesting 
genera Cyphophthalmus and Stylocellus, Westw., illustrated by 
four plates, has appeared in Troschel’s ‘ Archives’ (forty-second 
year, 3rd Heft, p. 298, 1876, 4to). The type of the new genus is 
named G. sudeticum, from the Bohemian Mountains. 

In Troschel’s ‘ Archives’ (forty-first year, Heft 1) Herr Kramer 
has published two memoirs on the mites of the family Gamaside. 
A memoir on the same family, by M. Megnin, appears in the 
‘Comptes Rendus’ of 20th November last. A curious new genus 
of Acaride, named Dendroptus, with two species, is described 
by Dr. Kramer in Troschel’s Archiv. f. Naturg. (forty-second 
year, 2nd Heft). An anatomical memoir on the Acaride, together 
with descriptions of some new genera of the family Gamaside, is 
given by Dr. P. Kramer in Troschel’s Archiv. f. Naturg. (forty-

A revision of the North-American Coleoptera formerly described 
by Mr. Randall has been published by Messrs. Sprague and 
Austin (Proc. Boston Soc. N. H. xvii. 387). 

Descriptions of various new species of exotic Coleoptera, by 
Charles O. Waterhouse (including an account of those collected 
in the Island of Rodriguez by the naturalists accompanying the 
Transit of Venus Expedition), appear in the ‘ Transactions’ of 
the Society and the ‘ Annals of Natural History.’ 

Baron Chaudoir has continued his labours on the Carabide, 
having published memoirs on the Cymindides and Siagonides in

HYMENOPTERA. 


The Tenthredinide and Cynipide of Scotland have received 
much attention from Mr. P. Cameron, of Glasgow, who has 
added “a number” of new species to the British lists, including 
monographs of the obscure and perplexing species of the genera 
Fenusa and Cladius (Entom. Mo. Mag., Jan. 1876, and ‘ Scottish 
Naturalist,’ vol. iv. p. 11). Inthe second volume of the ‘ Trans- 
actions of the Glasgow Society of Field Naturalists’ are also 
interesting and valuable papers on the gall-makers of the Glasgow 
district, by Mr. Cameron. Various new species of Tenthredinide 
and Siricidee (chiefly Indian) have also been described by Mr. P. 
Cameron in our ‘ Transactions.’ 

Mr. Trail has continued his descriptions of Scottish galls, 
commenced in the first and second volumes of the ‘ Scottish 
Naturalist,’ in the fifth volume of the same work, describing the 
galls (whether made by Cynipide or dipterous parasites) upon 
various species of plants which have been observed to be affected 
by them. 

The fourth volume of C. G. Thomson’s ‘ Scandinavian Hyme- 
noptera, Lund., 8vo, 192 pp., 1s devoted to the family Chal- 
cidide, the sub-families Pteromalides and Eulophides being 
reserved for a future volume. 

An elaborate monograph on the Encyrtides of Europe, by Dr. 
G. Mayr, extending to 100 pages, has appeared in the 25th 
volume of the Vienna Verhandlungen Zool. Bot. Gesellsch. 

Dr. Snellen van Vollenhoven has commenced the publication of 
an elaborate work upon the Linnean Ichneumons of the northern 
part of Europe, in which he proposes to give figures of not fewer 
than 1000 species, under the name of ‘ Pinacographia.’ Four 
parts have already appeared. 

Dr. Snellen van Vollenhoven has also continued his memoirs 
on the history and transformations of the Netherlands’ Tenthre- 
dinide in the ‘ Tijdschrift voor Entomologie, in which he has 
also given a complete list of the Tenthredinide and Ichneumo- 
nid, and allied families, inhabiting the Netherlands. 

Herr Ritsema has published a memoir on eight new Indian 
species of Xylocopa in the ‘ Tijdschrift voor Entomologie.’ 


An elaborate memoir, extending to sixty pages, 4to, on the 
K 


ew 


ants of Australia in the Godeffroy Museum at Hamburg, by 
Dr. Gustav Mayr, appears in the ‘Journal’ of that Museum, 
vol. xii. p. 56, containing fifty entirely new, in addition to the 
numerous species previously described by Smith, Lowne, Mayr, 
and other earlier writers. 


ORTHOPTERA. 


In the ‘ Ofversigt af Kongl. Vetensk. Akad. forhandlingar’ of 
Stockholm, for 1876, we find an extended memoir by Herr C. 
Stal, entitled “ Bidrag till Sédra Afrika’s Orthopter fauna.” With 
the single exception of a new species of Maxentius from the 
neighbourhood of the Cape of Good Hope, the whole of the 
species described in this memoir, of nearly fifty pages, are from 
Damara Land and Ovambo, and belonging to all the great 
divisions of the order. 

Mr. 8. H. Scudder has continued his contributions to the 
knowledge of the Orthoptera in the ‘ Memoirs’ and ‘ Proceedings’ 
of the Natural History Society of Boston, U.S. Four decades 
of his ‘‘ Century of New Forms” have recently appeared, the 
last (sixth) decade being entitled “Critical and Historical 
Notes on Forficulariz,” including descriptions of new generic 
forms, and an alphabetical synonymical list of the described 
species, which extends over fifty pages. He has also published, 
in the same work, ‘‘ Notes on the Orthoptera of Northern Peru,” 
with descriptions of forty-five species, including several new 
genera; and “ Spharagemon,”’ a genus of Cidipodide, and its 
species ; likewise a revision of Eneoptolophus and Tragocephala, 
two American genera of Gidipodide (Proc. Boston Soe. vol. xvi. 
p. 478). 


NEUROPTERA. 


Dr. F. Brauer (who has, I believe, succeeded Dr. Redtenbacher 
as Director of the Entomological Museum of Vienna) has pub- 
lished a ‘ List of the European Neuroptera’ (including those of 
Northern and Central Asia, Northern Africa, Syria, &c.), and 
comprising the whole of the species in the Linnean sense. The 
catalogue comprises about 1000 named species (but a number of 
these are evident synonyms), of these there are about 100 actual 
species of dragonflies,

A synopsis of the Odonata (Libellule) of America, by Dr. H. A. 
Hagen, is given in the ‘ Proceedings, Boston Soc. N. H. (xvii. 
p. 20—96). 


TRICHOPTERA. 


The fifth part (together with a Supplement to part 1) of 
‘A Monographic Revision and Synopsis of the Trichoptera of the 
European Fauna,’ with eight plates, by Robert M‘Lachlan, F.L.S., 
has appeared and fully maintains the classical character of this 
important work—a genuine labour of love, the preparation of 
which, with the very numerous figures of anatomical details, must 
have required a very large amount of time and patience, the 
fragile nature of the Caddis-flies rendering them very difficult of 
manipulation. | 

Dr. Brauer has published the descriptions of some new species 
of Trichoptera in the twenty-fifth volume of the Vienna Verhandl. 
Zool. Bot. Gesellsch. 


LEPIDOPTERA. 


Lepidopterists who for the last twenty-five years have 
periodically welcomed the beautiful plates of Mr. Hewitson’s 
‘Exotic Butterflies’ will regret the termination of that work 
with the fifth volume. The entire work comprises 300 plates, 
containing 2113 figures, illustrating not fewer than 1167 new 
species, together with 65 which had been previously figured in 
an unsatisfactory manner. It is to be hoped that the author will 
be spared to complete his separate work on the Lycenide, as well 
as his plates of the ‘‘ obscure Hesperide,” to which he alludes 1 in 
the preface of his completed work. 

The work commenced by Messrs. Felder, which was temporarily 
suspended by the lamented death of the younger author, has 
been continued through the past year by the publication of an 
elaborate set of plates containing an almost infinite profusion of 
figures of Nocturnal Lepidoptera, admirably drawn and coloured. 
The text, it is to be regretted, is unfortunately confined to a mere 
catalogue of the names and localities of the species figured. 

Descriptions of various new species of butterflies, and also of a 
remarkable new Attacus from Australia, have been published by 
Mr. Miskin in our ‘ Transactions.’ 

The beautiful work upon ‘The Butterflies of North America,’ 


ei 

by W. H. Edwards, has reached the fifth part of the Second Series 
(New York, 4to, 1876), containing an extensive series of illustra- 
tions of Colias Philodice, Argynnis inornata and rupestris, and 
Apatura Clyton and Proserpina, the synonym of which latter is 
cleared up by a communication which I was enabled to make to 
him of copies of Mr. Jones’ original figures, from which Fabricius 
drew his descriptions. 

Mr. Herman Strecker continues with unwearied zeal (con- 
sidering the difficulties of his position) his excellent ‘ Lepidoptera 
Rhopaloceres and Heteroceres,’ the last part (No.13) being devoted 
to the illustration of a number of difficult American species of 
Sphingide, admirably lithographed by the author, who has, in his 
usual style, seasoned his text with some sharp critiques of some 
of the Lepidopterous writers of the United States. 

Dr. Rogenhofer has published, in the twenty-fifth volume of 
the ‘ Verhandlungen’ of the Vienna Zool. Bot. Soc., a series ‘of 
descriptions of the larve of various butterflies and other Lepi- 
dopterous insects of Austria. 

The Lepidoptera of Patagonia form the subject of a memoir by 
Dr. Prof. C. Berg in the first volume of the ‘Acta’ of the 
Academy of Cordova, published at Buenos Ayres, and simul- 
taneously in the Moscow ‘ Bulletin’ for 1876 (p. 191). Amongst 
the Diurna one new species is described, Pieris Achamantis, near 
Ilaire and Mceneste. 

In the first volume of the fourth series of the Lille ‘ Memoires,’ 
we find a “Catalogue des Lépidoptéres du Département du Nord, 
par M. G. Le Roi” (omitting, however, all the Micro-Lepidoptera), 
extending to sixty pages. 

Mr. Butler has contributed numerous papers on different 
families of Lepidoptera to the Linnean and Zoological Societies 
and to the different periodicals, amongst which may be especially 
mentioned “A Monograph of the Pierideous Genus 'Teracolus,” 
comprising 129 species, with illustrations of twenty-eight 
species, published in the ‘ Proceedings of the Zoological 
Society’ (1876, p. 126); also ‘‘ Notes on a Small Collection of 
Butterflies from the New Hebrides” (ibid., p. 251); also “ De- 
scriptions of a few Eastern Lepidoptera from the Collection of 
Lieut. H. Roberts” (ibid., p. 308); also ‘Notes on Zygeenide,” in 
which he has corrected numerous errors of Mr. Walker and 
described numerous new species; and his memoir ‘“‘ On the Sub- 


lxix 


families Antichlorine and Chaeideimays? both published in the 
‘Journal of the Linnean Society,’ vol. xii. 

Descriptions of new American species of Noctuide, by H. K. 
Morrison, appear in Proceedings Boston Soc. N. H., xviii. p. 114. 

A valuable “‘ List of the Butterflies of Peru, with Descriptions 
of New Species,” by Mr. Herbert Druce, F.L.S:, &c., appears in 
the ‘Proceedings of the Zoological Society’ (1876, p. 205), with 
two plates. 

Descriptions of new Exotic Butterflies from various parts of 
the New World are given by Weymer, in the Entom. Zeit. of 
Stettin (xxxvi. p. 868). 

A memoir by George Semper on the Philippine Species of the 
Pierideous Genus Tachyris appears in the Ent. Zeitung of Stettin 
(xxxvi. p. 3938). 

Mr. 8. H. Scudder has published a ‘ Report on the Butterflies 
collected on the Yellowstone Expedition ;’ also “ Remarks on the 
old Genus Callidryas,” and ‘‘ Descriptions of some Labradorean 
Butterflies,” in the Proc. Boston Soe. (xvii.); and in his collected 
Entomological Notes, also ‘“‘ Notes on the Butterflies of Cape 
Breton Island (Proc. Boston Soe., xviii. p. 188), and an article on 
the small blue butterflies (Polyommati) of North America. : 

The curious Lepidopterous genus Eumeus, which I placed, in 
the ‘Genera of Diurnal Lepidoptera,’ at the head of the Lycenide 
has formed the subject of a memoir by Mr. 8. H. Scudder, who has 
fortunately been able to obtain the larva and pupa (the former of 
which I had not seen), published in the ‘Memoirs of the Boston 
Society of Natural History’ (vol. i1., pt.iv., No. 2), with figures. 

It will be sufficient for me, in this place, to notice the publica- 
tion by Dr. Boisduval of the first volume of the “ Species Général 
des Lépidoptéres-Heterocéres,” containing the Sphingide, Zy- 
geenide, Castnize, and allied groups. 

Memoirs by Mr. Grote on the North-American Noctue are 
noticed in the ‘Entomologische Zeitung’ of Stettin (xxxvi., 
pp. 97, 131, 345). 

We cannot sufficiently praise the admirable ‘ Monograph of the 
Geometrid Moths, or Phalenide, of the United States,’ published 
by Mr. A. S. Packard, jun, M.D., at Washington, 1876, 4to, 
pp. 606, with thirteen plates (forming the tenth volume of 
Haydon’s Report of the Geological Survey of the Territories). 
An excellent introduction, in which the Bibliographical history, 


oe 

the various anatomical characters of the group, and the classi- 
ficational details are given, is followed by careful descriptions of 
all the species, of which a great portion are represented in the 
elaborate [plates, much care having been taken to ensure the 
identification of many of the species insufficiently described by 
Mr. Walker by carefully prepared drawings of the types in the 
British Museum, made at the expense of the author. Following 
in the steps of Herrich-Schiffer, great attention has been devoted 
to the arrangement of the wing-veins of the different species 
represented in the first seven plates of the work, the remaining 
six plates being occupied with the figures of the perfect insects, as 
crowded as possible. 

The second part of the Micro-Lepidopterous portion of the 
work of H. von Heinemann and Wocke on the Lepidoptera of 
Germany and Switzerland has appeared (Brunswick, 1877, 8vo, 
825 pp. and 102 pp. of tabulation of species). 

Papers by Herr Ritsema and Mr. Dunning on the Genus 
Acentropus have appeared during the year. 

A memoir on new Lepidoptera from South America (Tortricide), 
by Dr. Staudinger, has appeared in the ‘ Verhandlungen’ of the 
Vienna Zool. & Bot. Society (vol. 25). 

A memoiw by P. C. T. Snellen on the Eastern species of 
Pyralide, forming the genus Oligostoma, is published in the 
* Tijdschrift v. Entomologie.’ 


HEMIPTERA. 


An extended memoir on the Hemiptera-Heteroptera of the 
Astrakan district—written in Russian, with characters of new 
species in German(!) and fuller descriptions in Russian—appears 
in the ‘Moscow Bulletin,’ 1875, part 3, occupying thirty pages. 
The inconvenience of such a publication is very great, as, for 
instance, we find the habitat, Sarepta, printed in Roman type 
on one page, whilst in the opposite one it appears as “ Capenta.” 
Fourteen new species and several new genera are described. 

The following part of the same ‘Bulletin’ contains a more 
extended memoir on the Russian Heteroptera, by the same 
author, with a plate. 

Mr. Uhler has published a list of the Hemiptera of the region 
west of the Mississippi River. 

We find in the ‘ Memoires of the Société des Sciences de Lille,’ 


lxxi 


4th ser., tome i., 1876, a second edition of a “Catalogue des 
Hémiptéres du Département du Nord,” par L. Lethierry (Hete- 
-roptera and Homoptera), extending to upwards of 100 pages. 

Dr. Horrath has recently published a “Monograph of the 
Hungarian Species of Lygzide,’ at Budapest, 4to, 109 pages, 
with 1 plate, containing 100 species, of which three are described 
as new, and which are represented by coloured figures in the 
accompanying plate. 

A memoir by Dr. Reuter, on the Hemiptera-Heteroptera of 
Austria, appears in the twenty-fifth volume of the Vienna Zool. 
and Bot., Gesellsch. 

P. R. Uhler has published a list of the Hemiptera and 
Neuroptera from Northern Peru, in the Proceed. Boston 
S. N. H., xvii. p. 282. 

A translation by Ferd. Rieber, of the memoir on the “ Cicadinz 
of Europe,” by Herr Fieber, appears in the ‘Revue et Magazin 
de Zoologie’ for 1876, extending through many numbers. 

We are indebted to the Ray Society for the publication of the 
first portion of Mr. Buckton’s excellent monograph of the British 
Aphidide, forming an octavo volume of 198 pages, with 38 coloured 
and 8 elementary plates. The family is divided into four sub- 
families,—Aphidine, Schizoneurine, Pemphigine, and Cher- 
mesinze,—characterised by the variations of the wing-veins. The 
first of these sub-families is divided into sections, from the 7- or 
6-jointed antenne; those with seven joints forming thirteen 
genera, and those with six joints forming five genera. The 
present volume is confined to the first six genera of the 
Aphidine. An interesting introduction of 100 pages gives a 
general summary of the anatomy and natural history of the 
family, in which it is to be noticed that after stating the different 
opinions on the subject of honey-dew, the author “is very much 
of the opinion that the honey-dew, as found upon leaves, is of 
Aphis origin;” and that “future enquiry will clear up the 
question whether this liquid is identical with that discharged 
‘from the cornicles” (p. 43). It is further to be noticed that, in 
plate B, the rostrum of these insects is represented as having 
“three long sete disengaged from the sheath: these are the 
representatives of the labium and maxille.’ This opinion is 
quite at variance with the generally-adopted view that the 
‘rostral sheath” itself is the representative of the labium, and 


xxii 


that the sete (four, not three, in number) represent the 
mandibles and maxille. 'The genus Syphonophora, being the 
most extensive in the number of its species (thirty-seven being 
described and figured), is preceded by a specific tabulation, which 
is not given in the genera Phorodon, Myzus, Drepanosiphum, 
Amphorophora, and Megoura. It is of course intended to give 
later specific characters and proper bibliographical references 
in an appendix, since the references, e.g., to “ Walk.,” involve a 
search through the whole English entomological literature of the 
last thirty years. 
DIPTERA. 

The following dipterous memoirs appear in the twenty-fifth 
volume of the ‘Verhandlungen’ of the Zool.- Botan. Gesellschaft of 
Vienna for 1875 :— Von Bergenstamm and P. Low, on new Ceci- 
domyie ; Dr. Grzegorzek, on new Mycetophilide ; Dr. Brauer, 
on a new Cistrus, parasitic on the Bonassus americanus, and on 
(istrus Shuckardi and the larve of several other species ; Prof. 
Palin, on Austrian Diptera. 

An excellent series of papérs on the structure of the parts of 
the mouth and other organs of various families of dipterous 
insects, illustrated with highly magnified figures by Mr. Under- 
hall, of Oxford, has appeared in ‘ Science Gossip.’ 

A complete synopsis of the sub-family of the gall-midges (Ceci- 
domyides) is given by Messrs. Von Bergenstamm and Léw in the 
Vienna ‘ Verdhandlungen’ for 1876, comprising a complete biblio- 
graphical list of works on the subject, a list of 463 described spe- 
cies, and of 1438 species of which only the larve have been observed, 
together with a list of the plants attacked by these insects. 

Count C. R. Osten-Sacken has continued his labours on the 
Diptera of North America, by the publication of the second part 
of his ‘‘ Monograph of the Tabanidee of the United States,” in the 
‘Memoirs’ of the Boston Soc. Nat. Hist., vol. i1., pt. 4., no. 4, 
with an appendix to the first part of his monograph: fifty-four 
species are described, of which nineteen are new; and forty-two 
species are recorded which have been described by other authors, 
but which remain unknown, unrecognized or doubtful. A list is 
also given of seventy-four species from Mexico, Central America, 
and the West Indies. Also an article on the North American 
species of Syrphus, and on some Diptera from the Island of 
Guadaloupe (Proc. Boston So¢., iv. N. xviil., part 2).

ENromoniocicaL NoMENCLATURE. 

The rules of zoological, and especially of entomological, 
nomenclature have attracted much attention during the past 
year, both in this country and in North America, where a 
Committee has been formed with a view to laying down some 
fixed principles, to obviate the terrible mischief resulting from 
the constant alteration of names on the ground of ‘ priority.” 
On this subject Mr. Samuel H. Scudder has published a 
** Historical Sketch of the Generic Names proposed for Butter- 
flies, being a Contribution to Systematic Nomenclature,’’-in the 
‘Proceedings of the American Academy of Arts and Sciences, 
New Series, vol. ii., 4to, Boston, 1875, pp. 91 to 293. 


Economic Enromouoey. 


The establishment of a cabinet of specimens, illustrating the 
economic uses and injuries of insects, in one of our national 
museums, is a subject of congratulation to those who look at the 
science beyond the mere collection and description of specimens. 
This has been done in the Branch Museum of the South 
Kensington establishment, at the Bethnal Green Museum, by 
the care of Mr. Andrew Murray, who has for several years 
paid especial attention to this subject, and who has contri- 
buted the first part of a descriptive catalogue of its contents 
(comprising the wingless species of insects), which has been 
published by the Government department of Science and Art. 

The Exhibition in the Jardin of the Tuilleries, in Paris, of a 
very extensive series of illustrations and specimens of Economic 
Hntomology, is especially to be mentioned, being the third of the 
series, and which was entirely formed by the assistance of country 
naturalists and entomologists, none of the leaders of the science 
in France being contributors. 

In the United States, Mr. Charles V. Riley, the State Entomo- 
logist of Missouri, has continued his labours, and has published 
his Eighth Annual Report on the noxious, beneficial, and other 
insects of that State, illustrated—as all his memoirs are—by 
admirable wood engravings; containing the potato-beetle, the 
army-worm, the rocky-mountain locust, the Phylloxera, and 
the singular butterfly whose caterpillar is known as the Yucca 
borer. 

L 


eo 

The ravages of the Phylloxera on vines continue unabated, 
and have become more and more widely spread. Numerous 
notices and papers on the subject have appeared in the various 
horticultural and other journals, including H. V. Haimhoffen’s 
article in the twenty-fifth volume of the Vienna ‘ Verhandlungen,’ 
whilst the different modes adopted for the prevention of the 
disease have been recorded in the ‘Comptes Rendus’ of the 
Académie des Sciences of Paris, and other journals. A most 
lamentable account of the result of the action of these insects in 
the vineries of some parts of France is given by M. Duchartre, of 
the Central Horticultural Society of France (Gard. Chron. 
January 13th, 1877). A summary also of the elaborate report 
made by Professor Mouillefert (who had been delegated by the 
Académie des Sciences to institute a series of experiments on the 
various proposed means of destruction of the Phylloxera) to the 
Académie, extending to 200 pages, is given in the ‘ Gardener's 
Chronicle’ January 20th, 1877 (whilst this Address is passing 
through the press), from which it appears that of all the various 
chemical materials which have been suggested, only sulphur 
compounds have been found at all efficacious. 

A curious memoir by Dr. F. A. W. Thomas on the action of 
the very minute mites of the genus Phytoptus, which he terms 
Acarocecidien, upon the leaves of many different species of trees 
and plants, appears in the thirty-eighth volume of the ‘Nova 
Acta,’ 1876, 4to, with three plates, showing the various modes in 
which the leaves are deformed by these minute creatures. A 
paper on the same subject by Dr. Léw appears in the twenty-fifth 
volume of the Vienna Zool. Bot. Ges. 

It may be in the recollection of some of the members of the 
Society that, at the time of the potato murrain in 1845, amongst 
the various causes of the disease, it was suggested by Mr. Alfred 
Smee (whose death, on the 11th of January, 1877, we have to 
deplore) that it was the result of the attacks of a species of Aphis, 
to which he gave the name of Aphis vastator—an opinion which 
obtained but little support amongst naturalists. Within the last 
few years the microscopical investigations of various fungologists, 
especially of Mr. Worthington G. Smith, have clearly shown 
the disease to result from the attacks of a minute fungus 
belonging to the genus Peronospora. It appears, however, from 
an article in the ‘Gardener’s Chronicle,’ for April 8, 1876, that 


lxxv 


Mr. Smee had made a collection of not fewer than 360 micro- 
scopical slides illustrating the disease on its first outbreak, and on 
these being recently examined by Mr. W.G. Smith it was found that 
a large number of the preparations of the potato Aphis exhibited 
the Peronospora in different stages of growth, and a highly 
magnified figure of the legs of an Aphis is given, showing the 
spawn-threads running through the limb and bursting out in 
parts developing the oogonia and the antheridia of the fungus. 
In this manner, and not by the action of sucking or poisoning the 
juices of the plant by the insertion of the rostrum of the healthy 
Aphis, the disease may be said occasionally to result from the 
presence of that insect.
